Use library with Arduino RP2040 Connect #24

Hi,

I'm building a robot using an Arduino RP2040 Connect. I want to control the robot using ELRS. I've uploaded the basic_crsf example to the board, it compiles just fine but I'm not seeing a signal. I'm not sure whether I'm using the right RX and TX pins on the board.

I see in the code you can select Serial1 or Serial2 but I'm not sure what they refer to. The Arduino pinout only lists one RX and TX so I tried that first but I also see that on the Pi Pico pinout there are other pins for other serial ports so I tried connecting to the equivalents of those pins.

Is there something else that I'm missing?

Thanks

Which board ID are you using? Looking at the pinout, try board ID 4 (you may need to modify some things in board defs to disable the led functionality), and wire it up to TX and RX pins on the Arduino Nano Connect RP2040
