Hi there,
So it is done that way for portability, The “Dx” labels (like D11, D12, etc.) are macros that correspond to nRF52 GPIO numbers defined in the board variant file (variants/xiao_nrf52840_plus/pins_arduino.h).
For example (approximate, depending on BSP version):
| Dx | nRF GPIO |
|---|---|
| D11 | P0.31 |
| D12 | P0.29 |
| D13 | P0.02 |
| D14 | P0.03 |
| D15 | P0.28 |
| D16 | P0.04 |
You can verify the actual mapping with:
Serial.print("D11 = "); Serial.println(D11);
Be aware of the BSP you use.
