Waveshare RP2040 LoRa

[ChiefBacon]

I found this board recently, and I was wondering if I could use it with Arduino Pico and this library. The board is basically a RPi pico with a SX126x built in, in a smaller form factor. I know that there was a warning for this library about limited RP2040 compatibility, but has anyone tried it? I do not have one of these in my possession yet, but will update once I have one and test with this library.

Using this info rp2040-lora

You should be able to use the library.
Things to find out

1. how is the RF switch controlled? That defines

• RADIO_TXEN (often used to power the RF switch)
• RADIO_RXEN (rare)
• USE_DIO2_ANT_SWITCH (common)
• USE_DIO3_ANT_SWITCH (rare)

2. How is the TCXO controlled? That defines

• USE_DIO3_TCXO

Then setup the initialization structure:

	// Define the HW configuration between MCU and SX126x
	hwConfig.CHIP_TYPE = SX1262_CHIP;		  // Example uses an eByte E22 module with an SX1262
	hwConfig.PIN_LORA_RESET = PIN_LORA_RESET; // LORA RESET
	hwConfig.PIN_LORA_NSS = PIN_LORA_NSS;	  // LORA SPI CS
	hwConfig.PIN_LORA_SCLK = PIN_LORA_SCLK;	  // LORA SPI CLK
	hwConfig.PIN_LORA_MISO = PIN_LORA_MISO;	  // LORA SPI MISO
	hwConfig.PIN_LORA_DIO_1 = PIN_LORA_DIO_1; // LORA DIO_1
	hwConfig.PIN_LORA_BUSY = PIN_LORA_BUSY;	  // LORA SPI BUSY
	hwConfig.PIN_LORA_MOSI = PIN_LORA_MOSI;	  // LORA SPI MOSI
	hwConfig.RADIO_TXEN = RADIO_TXEN;		  // LORA ANTENNA TX ENABLE
	hwConfig.RADIO_RXEN = RADIO_RXEN;		  // LORA ANTENNA RX ENABLE
	hwConfig.USE_DIO2_ANT_SWITCH = true;	  // Example uses an CircuitRocks Alora RFM1262 which uses DIO2 pins as antenna control
	hwConfig.USE_DIO3_TCXO = true;			  // Example uses an CircuitRocks Alora RFM1262 which uses DIO3 to control oscillator voltage
	hwConfig.USE_DIO3_ANT_SWITCH = false;	  // Only Insight ISP4520 module uses DIO3 as antenna control

Thanks for the reply, I suspected that it would work this way and I'll give it a shot when I get the board. I'll report back to here with the results.
