Dragino shield V1.3 : Pin mapping

[urs8000]

for the documentation // Pin mapping for Dragino Board Version 1.3 (open J_DIO5) const lmic_pinmap lmic_pins = { .nss = 10, .rxtx = LMIC_UNUSED_PIN, .rst = 9, .dio = {2, 6, 7}, // Specify pin numbers for DIO0, 1, 2 // connected to D2, D6, D7 }; not tested with LoRa/GPS shield!

ANY INFO: Dragino Board Version 1.4 ? Thanks

[henri98]

The pin mapping for dragino board version 1.4 are the same.

[MatGit5]

I can confirm it works with Dragino Board Version 1.4

may i ask it will also work with the Arduino Mega 2560 ? i did try since 2 days an i am not sure i am sending data.....gateway is recieving nothing at all. i dont have an UNO or an Feather...... Do you know there are special needs for the Mega ? Thank you so much for your help

[Roberto6969]

Actually not - it works fine with 2560 Core also: https://www.aliexpress.com/item/Mega2560-CORE-mini-2560-Arduino-compatible-3-3V-5V-for-Arduino-mega-2560/32603415477.html Just be carefull with pin mappings - there is many more pins on 2560

[Sasch600xt]

well....i am not a pro right now. "Just be carefull with pin mappings - there is many more pins on 2560"

ummm......i have no idea how to do the pin mapping..... I know i am asking for very much, but could one of you maybe have a look at the Arduino Mega pinout and tell me what to do ?

I think we talking about this section : `// Pin mapping const lmic_pinmap lmic_pins = { .nss = 10, .rxtx = LMIC_UNUSED_PIN, .rst = 9, .dio = {2, 6, 7}, };

by the way, it is a Dragino Shield

Thank you so much for your help ! Sascha`

[Roberto6969]

Here is my mappings: const lmic_pinmap lmic_pins = { .nss = 53, // 10 Connected to pin D10 .rxtx = LMIC_UNUSED_PIN, // 0 For placeholder only, Do not connected on RFM92/RFM95 .rst = 30, // 9 Needed on RFM92/RFM95? (probably not) .dio = {5, 6, 7}, // Specify pin numbers for RFM95 DIO0, 1, 2

In my case i use only RFM95 module (not Dragino) connected directly to 2560 Core. Used pins between RFM95 and 2560 Core are: RFM95 - 2560 Core name and pin number

MISO - PB3 22
MOSI - PB2 21
SCK - PB1 20
NSS - PB0 19
RESET - RESET 30 DIO0 - PE3 5
DIO1 - PH3 15
DIO2 - PH4 16

If you use Dragino this will help you: http://wiki.dragino.com/index.php?title=Lora_Shield

Can anyone tell me what the dragino pin mappings are with Leonardo?

I tried the following and almost bricked my leonardo.

const lmic_pinmap lmic_pins = { .nss = 10, .rxtx = LMIC_UNUSED_PIN, .rst = 9, .dio = {2, 6, 7}, };

[matthijskooijman]

@mantoles, the Leonardo should have the same pin numbers for digital I/O as the Uno, so that pin mapping should be correct. However, the Leonardo does not have SPI pins available on digital pin 11/12/13, only on the 2x3pin ICSP connector. I haven't checked the dragino board, but if that board assumes SPI on 11/12/13 and does not have the 2x3 pin connector, you'll have to reroute the SPI connections somehow (i.e. add wires, maybe cut pins or traces on the Dragino).

[mantoles]

@matthijskooijman Much appreciate your response. Now it makes more sense. The leonardo has the 2x3 ISP connector so it should be connected to the spi bus directly.

Good morning, I am using an Arduino Mega 2560 board with a LoRa Shield having the RFM95W radio module. However I use LMIC to send my data to a Dragino LPS8N gateway. And when I upload my program to the Arduino board nothing happens and I get the error displayed on the serial monitor: Arduino\libraries\LMIC-Arduino\src\lmic\radio.c:689

I thought at first it was a pin mapping problem but I still have the same problem. Help me please. Here is my test code on arduino:
