Support for adafruit_feather_rp2040_rfm9x

[mdede439]

Adafruit recently developed and released a new RP2040 board with a LoRa module installed. It is different than the standard RP204 with an externally attached LoRa module. Is there an easy way to modify the definition of "-DPICO_BOARD=adafruit_feather_rp2040" to the newer board?

When I use the otaa_temperature_led example it fails to initialize the the lorawan.
I get this error;

Pico LoRaWAN - OTAA - Temperature + LED

Initilizating LoRaWAN ... failed!!!

I am pretty sure it is because of the design differences in the two boards.

I was able to get the new Adafruit RP2040_RFM95 board to work by modifying just the GPIO pins used for the LoRa module. I thought there would be more to it!

const struct lorawan_sx1276_settings sx1276_settings = { .spi = { // .inst = PICO_DEFAULT_SPI_INSTANCE, .mosi = 15, .miso = 8, .sck = 14, .nss = 16 }, .reset = 17, .dio0 = 21, .dio1 = 22 };

@mdede439 great work!

Have you asked Adafruit if they plan to add a .h here for the board in the pico-sdk? https://github.com/raspberrypi/pico-sdk/tree/develop/src/boards/include/boards

I have not done this but will open a new question in their forum.
