Support for adafruit_feather_rp2040_rfm9x
Closed this issue · 4 comments
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.
