Waveshare 3.2inch rpi lcd for the Raspberry

[videobuff]

Is there any support for this display coming up ? http://www.wvshare.com/product/3.2inch-RPi-LCD-B.htm I have btw the previous version (without the B). Erik

[notro]

It doesn't say which LCD controller the display uses on that page.

I see the display comes with an image. Isn't that good enough? If they use FBTFT on that image, see if you find a module starting with fb_ in /sys/module

LCD shields for the Pi is popping up all over the place now. Seven months ago it was only a handful: https://github.com/notro/fbtft/wiki/Raspberry-Pi-Display-shield-comparison

[ghost]

I have also the old one, but wasnt succesfull getting it to work - to be honest, havnt spent a lot of time. Is it a ssd1289, at least the driver is named that way, probably I have used wrong kernel parameters for the module.

BTW, this is what the manufacturer supplied:

PIN NO. SYMBOL DESCRIPTION 1, 17 3.3V Power positive (3.3V power input) 2, 4 5V Power positive (5V power input) 11 TP_IRQ Touch screen interrupt, low level while the touch screen detects touching 12 KEY1 Key 13 KEY2 Key 15 KEY3 Key 19 LCD_SI/TP_SI SPI data input of LCD/touch screen 21 LCD_SO/TP_SO SPI data output of LCD/touch screen 23 LCD_SCK/TP_SCK SPI clock of LCD/touch screen 24 LCD_CS LCD chip selection, low active 26 TP_CS Touch screen chip selection, low active

Any help whould be appreciated. Thx, Florian

[notro]

Since there is no DC/RS pin I assume it's using the 3-wire SPI mode, which on this controller means 9-bit SPI. From the top of my head:

sudo modprobe fbtft_device custom name=fb_ssd1289 speed=8000000 buswidth=9 width=XX height=XX

If the width/height of your display differs from 240x320, you have to provide your own init= sequence. The default one assumes this. Panels differ, so you might have to provide one anyway.

https://github.com/notro/fbtft/wiki/fbtft_device

Didnt work, but I have done a little more research on these piece of hardware. It is an exact copy of valdodov's circuit and was delivered with the precompiled kernel/modules/configs from his web site.

There was already a ticket in Mai #115 on that matter, is there any chance to get it working ?

Thx, Florian

[balkian]

I can't get it to work either. Unfortunately, my display didn't come with an image.

Cheers.

[notro]

It is an exact copy of valdodov's circuit ... is there any chance to get it working ?

No plans to support that circuit.

[that-scientist]

I found a custom raspberrian image for this display on a dutch website here: http://eckstein-shop.de/Plug-and-Play-32-inch-Touch-Screen-TFT-LCD-for-Raspberry-Pi-A-/-B-/-B-_1 NOTE: the archive is password protected (dick move). I've posted on their site to ask for the password. UPDATE: password for archive is "eckstein", will now see if this is the image we seek.

I also emailed the manufacturer, will post again if either of these leads work.

[that-scientist]

Manufacturer refuses to offer any help:

"It seems like the picture is ours.........

If the reseller bought the LCD from us then resell to you, then they must have the CD, as we have CD for each of this LCD screen. We don't have links for download, all the contents for the LCD are contained in the CD, it should be the resellers problems who did not send the user guide CD to the package.

You can image that if all of the reseller, to whom we have already provided the CD for the products, then they don't send it to customers, then how can we provide the direct services to customers?

Thank you for your understand. Johanna Liang ~O(∩_∩)O~

[ant42]

Any news on this topic? I am currently also using one of those displays with the image supplied by eckstein. Although this seems to work fine so far, I would prefer to switch to a more open solution (for more recent kernels, etc).

[balkian]

I copied configuration of the module from that image. It should work but I haven't had the time to try it yet:

[imaginal]

I also have Waveshare 3.2inch RPi LCD (B) V3 connected to Raspberry Pi Model B+ http://www.wvshare.com/product/3.2inch-RPi-LCD-B.htm http://www.amazon.com/Waveshare-Raspberry-Resistive-Interface-Rapsberry-pi/dp/B00N0SNVQE

I have found that the initialization string is very close to fb_ili9340 driver, so after few days of testing I found this configuration is pretty stable

1. Use FBTFT drivers built into the kernel

sudo REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update
sudo reboot

2. After rebooting, check that SPI was created

# dmesg | grep spi
 Linux version 3.12.25+ (pi@raspi2) (gcc version 4.8.3 20140106 (prerelease) (crosstool-NG linaro-1.13.1-4.8-2014.01 - Linaro GCC 2013.11) ) #1 PREEMPT Sat Aug 2 19:08:33 CEST 2014

3. Add to /boot/cmdline.txt (in one line)

fbtft_device.custom
fbtft_device.name=fb_ili9340
fbtft_device.gpios=dc:22,reset:27
fbtft_device.bgr=1
fbtft_device.speed=48000000

4. To enable console on boot add to /boot/cmdline.txt

fbcon=map:10
fbcon=font:ProFont6x11
logo.nologo

5. Also may be useful to add

dma.dmachans=0x7f35
console=tty1
consoleblank=0
fbtft_device.fps=50
fbtft_device.rotate=270

[Talabo]

I've managed to make this work. But has anyone figured out how to make Waveshare 3.2inch RPi LCD work in GUI (startx)? As long as I have a HDMI connected I can see the GUI from an extra screen.

[imaginal]

you want to use them separately or simultaneously? maybe fbcp will help https://github.com/notro/fbtft-spindle/wiki/FBTFT-image#fbcp---framebuffer-copy

[Talabo]

I treid fbcp. It copies the big screen (connected through HDMI) which is hanging, into the Waveshare 3.2inch RPi LCD (B) V3. So both screens seems like they hang.

But this is how it's to me.

Normally after making the Waveshare 3.2inch RPi LCD (B) V3-screen work, raspbian runs fine with the little screen. As I only boot into console/terminal. But if I'm going to GUI (startx) the tiny screen hangs.

While booting with an extra screen connected on the HDMI-plug. The extra screen hangs, and the tiny one works fine and mentioned.

When I do the "startx"-command, the HDMI-plugged screen is the one working good in GUI. While the tiny screen hangs.

I wanted to make it so that the tiny screen is standalone and possible to run into GUI (startx). I see the use of fbcp, but it's not for my use.

What I want to do, is to make the tiny screen run fine in GUI (startx). And I'm wondering if you have managed to do that :)

Than you for your time :)

[Kingurus]

I have a 3.2inch RPi LCD (B) V3 from waveshare. It came with their DVK512 which includes a CD with an SD image that makes X work on the LCD. Image is Linux raspberrypi 3.12.25+ with (I guess) their custom command: LCD32-SYS-SHOW-V3 which reboots with x on LCD.

[Talabo]

You say the Image is Linux raspberrypi 3.12.25+, so not raspbian customized?

Hmm, do you by any chance have the possibility to upload this anywhere?

[Kingurus]

It is too big to upload... It must be available somewhere already. Check this out : http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=89127

[Talabo]

Thank you! Found this link which have .pdf and the software. So no need for downloading a whole new image into the rasp. pi. Will try this when I have time.

[faithoflifedev]

I got my Waveshare 3.2inch LCD working great using the instructions above provided by "imaginal". I now want to be able to turn off the backlight. Has anyone been able to do this? Is the functionality supported?

[andrealvarez]

Does anyone know how can i turn off the backlight? for the Waveshare 3.2inch LCD

I have been googling everywhere and i cant seem to find it...

[andrealvarez]

Notro nevermind im going to buy adafruits one and return this chinese one... Thanks :)

[lunarcms]

Hiya all.

I have a WaveShare SpotPear V4 LCD with a Raspbian image (unfortunately with loads of excess baggage included, the image is just over 4GB).

I should be able to get it onto the web shortly (give me a few days), I also plan on stripping it back to a very minimal Raspbian with OpenBox and a few utils such as SSH if anybody is interested?

[PathicEnyrgis]

@lunarcms I am very interested, I received my waveshare today and need to use it for first test of my pi b+, I do not have an hdmi monitor.

3.5in rpi LCD (A). Current name of image on the disk: LCD35-14120 So from the instructions on the disc. I believe it is rasbian with display drivers. Now how bad is the bloatware?

I need to format the sd-noob card ( only 4gig card I have) Is it worth losing the noob software and images?

[alpha-ninja]

Could someone look into why drivers built into the kernel is the only way that seems to work?

[gadget9503]

would love to make Kodi 14.1 work with this display have tried different configs but all give me some kind of error ie-can't find file, can't find dir, debends on xbmc-deb, no make etc, any help would be great.

Mike

[alpha-ninja]

Okay, I've fiddled around with this stuff. In /etc/modules I have: fbtft_device custom name=fb_ili9340 speed=48000000 gpios=dc:22,reset:27 bgr=1 rotate=270

I added to /boot/cmdline.txt: fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo

The console on startup works just fine, but for some reason, I can't find out how to launch framebuffer applications on the tft display.

I tried su -l pi -c "env FRAMEBUFFER=/dev/fb1 startx &", but that resulted in the tft display being cleared and X starting on the HDMI display.

Any ideas?

If Raspian, you need to change fbdev option in /usr/share/X11/xorg.conf.d/99-fbturbo.conf

"I should be able to get it onto the web shortly (give me a few days), I also plan on stripping it back to a very minimal Raspbian with OpenBox and a few utils such as SSH if anybody is interested?"

@lunarcms, that would be wonderful. I had a pretty rough time with setting up a 4" Waveshare display because I only had a 4 GB Micro SD and the manufacturer probably had expended all the available space. Have you set something like that up? I couldn't find drivers or a kernel to make the screen work. Doesn't feel right to have an outdated Raspbian (well, the GUI) with a load of junk installed.

EDIT: Wait, by "V4" did you mean 4 inch or is that unrelated, haha?

[that-scientist]

That would be super. I would like to use this for a touch screen tool, so a simple distro would help!

I recently bought the lcd from this site "https://www.crazypi.com/raspberry-pi-products/Raspberry-Pi-Accessories/32-TOUCH-DISPLAY-RASPBERRY-PI".I got a DVD which contain the image file.I am using a B+ board.I burned the image to sd card.But when i power on the board by plugging the display,LCD is completly blank,no backlight ?Please help.I connected a keyboard with raspberry pi through USB port.When i pressed caps lock in keyboard the caps lock light glowed in keyboard.So i think Pi is booting correctly.But LCD is blank.How to check wheather the problem is with SD card,Pi or LCD ?????

[notro]

Please contact the seller. They know their display and image.

[CasperHedegaard]

Maybe the images for the Odroid which supports the LCD can help?

Any one has success with Waveshare 3.2inch V4 on Raspberry Pi 2 Model B? I tried with image on CD came with it, but no success. It just show Multi Colored Big Block on the screen that cover 90% of screen. And there no response from raspi at all.

Also Tried with Fresh new image of Raspbian 2015-2-16 and running: sudo REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update sudo reboot

Get exact same Multi Colored block on initial screen, same as I get with Image from CD.

Any help?

[gadget9503]

sounds like it is booting in hdmi mode.  try pluging a monitor in the hdmi port and rebooting.

Yes, I did that. It was connected with Hdmi, as it was showing that on monitor. Noticed this is the very first thing usually show on monitor for few second befit continue with boot. But not it look like stuck on intial screen and won't continue.

Anyone got it working with splash screen on boot? I tried to follow instruction from https://github.com/notro/fbtft/wiki/Bootsplash

But seems something missing as it does not work for me. Any help?

[notro]

initramfs is done differently with the current Device Tree kernels. I haven't had time to look into it. There's something in this thread: http://www.raspberrypi.org/forums/viewtopic.php?p=685709&sid=61c7334eb300ad23c03fb28f94e37d7c#p685709 If you make it work and have the time, please update the fbtft bootsplash wiki page.

[Vineetsai]

Notro, I'm not very much experience with RPi, new learner here. If you can point me to some source I can definitely try. Above link has some info but not able to make out much sense out of it as I'm not even sure what initramfs does and why it used other than is loaded initially during boot sequence.

Any pointer would be helpful for me to look for solution.

On Side note: I tried to do BRANH=builtin rpi-update expecting with get kernel with built into it and that might help, but that also got my LCD screen to go back to white blank and when check on hdmi output it stuck with initial Rainbow screen and no progress with boot.

[notro]

BRANCH=builtin is deprecated. I haven't got time to make it anymore. As soon as we get a SPI DMA driver in the official kernel release, I will stop releasing the BRANCH=master kernel also.

initramfs is loaded very early in the boot process, and at that point you can load the fbtft drivers and plymouth will also start if enabled.

Divide your work into steps, first find out how to make and load an initramfs, then when it works, start filling it. I use google when I don't know how to do something. Usually I get multiple takes an the problem.

I bought the v4 version (http://www.aliexpress.com/item/3-2-LCD-Touch-Screen-Display-Monitor-Case-Heatsinks-for-Raspberry-Pi-B/32235705777.html) and managed to get it working on a pi1 model B with raspbian installed. Does anyone have a GPIO script to control the buttons ? Basically i want to turn the display on/off by pressing a button. I found this: http://www.circuitbasics.com/raspberry-pi-touchscreen-calibration-screen-rotation/#comment-145 but i cant find any command to turn the screen on/off to use it.

[maty87]

Hi when doin the 1st step Touchscreen Setup and Configuration

1. First we need to configure the fbturbo video driver to output the display of the Raspberry Pi to the SPI bus instead of the HDMI bus. At the command prompt, enter: sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf

I get it come up but its empty nothing in it atall

[maty87]

I followed these steps but on reboot it just hung on the following screen

rebuilding rasbian now all I know about my screen is as it says on back 4INCH RPI LCD(A) WAVESHARE SPOTPARE

I kbow the screen works with the supplied image but don't wanna use theres cus i wanna use mine so i can chose to boot rasp or openelec

[maty87]

heres a script of the info I see from the given image from following the guide steps could it be possible to just copy these into the original official rasb image

step1 file is empty

step 2 GNU nano 2.2.6 File: /etc/modprobe.d/raspi-blacklist.conf

blacklist spi and i2c by default (many users don't need them)

#blacklist spi-bcm2708 #blacklist i2c-bcm2708 blacklist snd-soc-pcm512x blacklist snd-soc-wm8804

step 3 not done as screen working

ste 4 file is empty

step 5 GNU nano 2.2.6 File: /boot/cmdline.txt

Any ideas ?

[starwolf73]

Hi, I also have the same issues but just found out the drivers and manual on the Wiki http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B)

At work, so I will try to test it on the week-end.

This is was i found too... but no luck... the same as described... hanging at booting at:

using Raspian Image from 05.05.2015..

[starwolf73]

I little workout around but it WORK fine on Pi 1 & Pi2!

Since I had a few extra MicroSD card, I install a fresh Raspbian from Feb (3.18.5-v7+ ) on one and install the drivers has suggest in http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B). It WORK! Speed is great and touch work very good without any calibration. I will have more time to play with it on Sunday and see if we do a upgrade it break the drivers.

[Vineetsai]

Does new rasbian release in May include fbtft with kernel? Or it still need to build module and include with kernel manually?

I was able to run also the latest Raspbian image (May) and it work well. Just make sure to block the bootloader update before any apt-get upgrade. See the Wiki for more info since I'm away from home for now.

[Vineetsai]

So new release still need to follow all steps from wiki including installing driver? As I thought drive is included with kernel and will be part of kernel modules, is that not correct?

Well, I'm still new to raspi. I do know that my LCD work fine for now with a fresh image and drivers installation. If I have the time this week, I'll try to go a little deeper and understand what the script is doing and post my research.

[Big111156]

not one of described Solutions worked for me.... so i think either this Display is defective or not compatible with my Raspberry Pi B (no + or 2)

:-(

[starwolf73]

@Big111156 Did you try with a fresh Raspbian image (3.18)? And did you install the driver with the command LCD32-show? Also you may want to check to turn on DEVICE-TREE and SPI option in RASPI-CONFIG?

Hi everyone, so I've been fighting with my new screen for a few days now and after reading all the posts I could find, and banging my head on the keyboard I finally tried this: http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B) (posted by starwolf73 above) I followed the instruction on the site and it just works perfectly.. no calibration, no problems. Also when I tried to download the package from the above site it was taking a year (20k/s), so I found this as a mirror, and it seems to be much faster: https://ecksteinimg.de/Datasheet/LCD-show.tar.gz

Hope this helps some of you, cheers..

[ieidsath]

Hello, just wanted to share the setup I have for running the Waveshare 3.2" V4 display on a Raspberry Pi model B rev. 1 using Arch Linux.

Took me a couple of days to figure it out, but after piecing together information from various posts (many thanks to notro, Hexxeh, Imaginal, the tutorial at http://www.circuitbasics.com/setup-lcd-touchscreen-raspberry-pi, and the Waveshare wiki), I hacked together a working setup.

Step 1) Install rpi-update and firmware

With root permissions:

pacman -S wget
wget https://raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update -O /usr/bin/rpi-update
chmod +x /usr/bin/rpi-update

Then I install the builtin branch for notro's rpi-firmware:†

REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update

Step 2) Configuring modules

I would recommend doing the following by SSHing into the device. You'll be copying large amounts of text and if nothing is displayed on bootup you can recover easily.

With root permissions:

Insert the following line in /boot/config.txt to enable SPI:

dtparam=spi=on

Edit /etc/modules-load.d/raspberrypi.conf and insert the following modules for SPI, display, and touchscreen drivers:†

spi_bcm2708
fbtft_device
ads7846_device

Create the file /etc/modprobe.d/fbtft.conf. Copy the line in, but pay close attention to the gpio pins:‡

options fbtft_device name=waveshare32b width=320 height=240 gpios=dc:22,reset:21 bgr=1 speed=48000000 buswidth=8 rotate=270 init=-1,0xCB,0x39,0x2C,0x00,0x34,0x02,-1,0xCF,0x00,0XC1,0X30,-1,0xE8,0x85,0x00,0x78,-1,0xEA,0x00,0x00,-1,0xED,0x64,0x03,0X12,0X81,-1,0xF7,0x20,-1,0xC0,0x23,-1,0xC1,0x10,-1,0xC5,0x3e,0x28,-1,0xC7,0x86,-1,0x36,0x28,-1,0x3A,0x55,-1,0xB1,0x00,0x18,-1,0xB6,0x08,0x82,0x27,-1,0xF2,0x00,-1,0x26,0x01,-1,0xE0,0x0F,0x31,0x2B,0x0C,0x0E,0x08,0x4E,0xF1,0x37,0x07,0x10,0x03,0x0E,0x09,0x00,-1,0XE1,0x00,0x0E,0x14,0x03,0x11,0x07,0x31,0xC1,0x48,0x08,0x0F,0x0C,0x31,0x36,0x0F,-1,0x11,-2,120,-1,0x29,-1,0x2c,-3

Step 3) Bootup commands

Back up /boot/cmdline.txt to your home folder if you need to restore it later.

cp /boot/cmdline.txt ~/cmdline.txt.bak

Erase everything in /boot/cmdline.txt and copy this line:

root=/dev/mmcblk0p2 rw rootwait selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=ttyAMA0,115200 elevator=noop fbtft_device.custom fbtft_device.name=waveshare32b fbtft_device.gpios=dc:22,reset:21 fbtft_device.bgr=1 fbtft_device.speed=48000000 fbtft_device.fps=50 fbtft_device.rotate=270 dma.dmachans=0x7f35 console=ttyAMA0,115200 fbcon=map:10 fbcon=font:VGA8x8 console=tty1 consoleblank=0

(This will boot into the command line on the Waveshare display. If you want the command line on your primary display with HDMI or NTSC, remove "fbcon=map:10 fbcon=font:VGA8x8". Booting fbcon this way is deprecated in future releases.)

Step 4) Reboot

That's it! The display should work and you should see the command line on it now.

† The builtin branch is deprecated, but I got a square display with unused white bars on the side when I set it up with the newer kernel. I haven't figured out a solution yet. Keep in mind that fbtft_device, ads7846_device, and fbcon might not work the same way in newer releases. ‡ The Raspberry Pi Rev. 1 models A and B have a slightly different pinout for GPIO. GPIO21 was changed to GPIO27 in all future revisions, so change the reset pin accordingly.

[joelstitch]

I have a WaveShare 3.5 RPI LCD (A) (http://www.wvshare.com/product/3.5inch-RPi-LCD-A.htm) and cannot get it to work following this guide. I have Kali Linux installed with TFT made specifically for the Raspberry Pi (including A). I followed ieidsath guide and first /boot/config.txt and /boot/cmdline.txt did not exist (don't know if that has anything to do with it not working). Besides that I followed the instructions and it still shows the display on the HDMI and none on the LCD screen.

[Sergehog101]

Hi All,

I have purchased one of these Spotpear V4 boards to run on a Pi2 B. After contacting the supplier here is the link for a image configured for the display. http://www.spotpear.com/download/image/RPi-2.4inch_3.2inch-LCD-150602.7z Or http://www.spotpear.com/download/image/ for alternate displays. installing this image on a sd card I can confirm all works correctly including the touch screen on my Pi2. Hope this helps.

[zheli]

@ieidsath thx for the info on rev 1! Finally figure out why it didn't work on my board :smiley:

[AaronPelzer]

@Sergehog101 you are the insanity saver!! Been figuring this for days -

[ayasystems]

Could you talk as more about this image??

What is the SO based? Debian? Version kernel?

Did you try to make a dist-upgrade ? Is it working after upgrade ?

[mrwolf81]

for all of you trying to get the following screen to work on pi B rev1 http://www.waveshare.com/3.2inch-rpi-lcd-b.htm you need to download the image from the website, install/write to SD card, then sudo nano /etc/modules and change this bit: gpios=dc:22,reset:27 to gpios=dc:22,reset:21 and your screen will work ...and work in startx i don't think anyone has been paying any attention to the pin-outs of their screens and the pin-outs of the gpio's on their versions of the raspi! if it doesn't match the code... it ain't gonna work!

[dhineshc]

Hi notro, I am using chromium OS in raspberry pi 3 board with waveshare 3.2 inch TFT display. Chromium OS has Linux kernel 4.4, FBTFT drivers are built part of kernel. I followed the overlay procedure with the waveshare dtb, but on boot up, it gets stuck with the following kernel messages. Any solution ??

[notro]

Use a HDMI monitor to see if there are more messages. FBTFT won't display panic messages.

[fbettag]

Allright, the only thing y'all need to do is follow the dts/dtb instructions here: https://github.com/swkim01/waveshare-dtoverlays

Basically copy the dtb file to your /boot/overlay/, add dtoverlay=waveshare35a to config.txt, reboot. Done :)

[aoyawale]

@fbettag does that include the raspberry 3? I just got this LCD and tried to do what is on waveshare page http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B) but, I get a kernel panic when It reboots.

[fbettag]

yes should work for rpi1-3. I had it plugged on my 2 and 3, dunno where my 1 is

[aoyawale]

just tried it and all I get is a block screen during boot. It shows a bit of the booting process then goes blank.

[fbettag]

well if it shows your cli during boot then it works, you're just suffering some misconfiguration. Xorg and fbcp setup properly?

[aoyawale]

where can I find how to configure those? I appreciate the help.

[fbettag]

maybe my blogpost helps http://uberblo.gs/2016/12/kali-on-the-raspberrypi-with-3-5inch-lcd

[mrwolf81]

dhineshc

Change your pinouts references Dc = 22 Reset = 25 on pi3 i think And make sure you've checked the information others have posted on this. Send more screen shots of all the info during boot

[mrwolf81]

Sorry correction DC = 22 (GPIO 25) RESET = 21 (GPIO 9) Do not use 27 as reset, that is the I²C id for the eeprom

Sudo nano /etc/modules Change fbtft_device name=waveshare32b gpios=dc:22,reset:27 speed=48000000

To this fbtft_device name=waveshare32b gpios=dc:22,reset:21 speed=48000000

The below is how i set mine up, just changed the gpios to match pinouts of the screen & pi Www.circuitbasics.com/setup-lcd-touchscreen-raspberry-pi/

Hi, I try to replace my squeeezeboxplayer using raspeberry pi 3, picore player (tinycore linux) and my waveshare 3.5. I tried all procedure I known but I still have a white screen (the HDMI is working correctly). do you have a procedure for tiny core ( kernel 4.4.39) that I could use without having X11 installed? thanks for your help
