RP2040-LoRa Development kit

[ObiLeek]

I've been puzzling for a few days how to make this development kit work with this library. Here is the link to the wiki: https://www.waveshare.com/wiki/RP2040-LoRa

I'm trying the sample examples with a modified pinout:

#define NSS_PIN 13 // SPI Chip Selection (low active)
#define DIO1_PIN 16 // SX1262 interrupt output pin or special function pin
#define RESET_PIN 23 // Reset pin, low active
#define BUSY_PIN 18 // SX1262 BUSY Pin

But it just won't and won't work, I keep getting an error:
failed, code -2

I would suggest to fill in the "module not working" template. In there, you will find a link to RadioLib Troubleshooting Guide, which I believe will help you greatly ;)

That was the first thing I did, but to no success.

That was the first thing I did, but to no success.

If you filled the template in, can you post it here, that's the first step in getting some meaningful assistance.

Similar to #729, for this module you have to use hardware device SPI1 (instead of the default SPI0) and configure the pins for SPI1 accordingly.

Ah, that's where that nugget of information had disappeared to, thanks for finding it.

Thank you, that was exactly right. In my particular case, like this:

Module* mod
MbedSPI SPI1(24, 15, 14);

void setup() {
      mod = new Module(LORA_CS, LORA_DIO1, LORA_RST, LORA_BUSY, SPI1);
}

In my specific case with this modul LINK, tcxoVoltage had to be set to zero.
