STM32_TFT_8bit

STM32_TFT_8bit copied to clipboard

Hi. can you help me with your lib, i run your examples, but it doesnt work, only white screen, i checked pins, all connected right

It's to know the model number of the chip used for your TFT module that you should do first.

Arduino https://github.com/prenticedavid/MCUFRIEND_kbv/blob/master/examples/LCD_ID_readreg/LCD_ID_readreg.ino

Raspberry Pi https://github.com/nopnop2002/lcd_id

It's the same outward appearance, but mcufriend has a lot of variations. http://domoticx.com/arduino-shield-2-4-tft-lcd-touch/

And Sailor's information makes a mistake in most cases.

i had this output Read Registers on MCUFRIEND UNO shield controllers either read as single 16-bit e.g. the ID is at readReg(0) or as a sequence of 8-bit values in special locations (first is dummy)

but then i tried sketch from another issue and the output is

This is real pfd5408.

reg(0x0000) 54 08 ID: ILI9320, ILI9325, ILI9335, ...

Your LCD is the one I don't know.

Your TFT may be ILI9340.

reg(0x00D3) 00 00 93 40 ILI9341, ILI9488

But it's not support.
