Hello everyone.
I'm trying to run the example arduino-lmic/examples/ttn-abp/ttn-abp.ino at master · mcci-catena/arduino-lmic · GitHub to send a "Hello World" via LoRa, but I'm having trouble.
I noticed there's no clock signal and no signals on the MOSI and MISO pins either.
The code isn't allowing communication.
Since I'm using the ATMEGA4809, perhaps the #include <lmic.h> library is assigning pins that aren't designated by the ATMEGA4809. Could someone tell me how to assign the pins correctly for the ATMEGA4809?
NSS 7
SCK 6
MISO 5
MOSI 4
NRESET 40

* This example sends a valid LoRaWAN packet with payload "Hello,
* world!", using frequency and encryption settings matching those of
* the The Things Network.
*
* This uses ABP (Activation-by-personalisation), where a DevAddr and
* Session keys are preconfigured (unlike OTAA, where a DevEUI and
* application key is configured, while the DevAddr and session keys are
* assigned/generated in the over-the-air-activation procedure).
*
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
* violated by this sketch when left running for longer)!
*
* To use this sketch, first register your application and device with
* the things network, to set or generate a DevAddr, NwkSKey and
* AppSKey. Each device should have their own unique values for these
* fields.
*
* Do not forget to define the radio type correctly in
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.
