3/9/2024 0 Comments Arduino mega 2560 spi pinoutI have done the Pin mapping below following the board branch shown here ’s%20manual.pdf:īut I still have the same error. Now it no longer puts \LMIC-Arduino\src\lmic\radio.c:689 but rather \MCCI_LoRaWAN_LMIC_library\src\lmic\oslmic.c:53. Sorry, that’s when I had the old version of LMIC. Or an Uno, which won’t have the space to run the LMIC but you can at least run the diagnostic library. If another SPI device won’t work, then I’d suspect the Mega or the other device. ![]() It that’s not able to talk to the radio I’d unplug the shield, try another SPI device to test that on the Mega and if that works, use jumper cables to link the shield to the Arduino. The thing to try after checking the pin matching when you plug it in if that doesn’t make it work is to scroll up this thread to the very top and use library to run some diagnostics.
