Hi,
Not sure it will help but I recently tried to use a Semtech LoRa radio with an
Arduino Zero and using a second SPI (for the radio) was working with the
following configuration:
{
.dev = &SERCOM1->SPI,
.miso_pin = GPIO_PIN(PA, 19),
.mosi_pin = GPIO_PIN(PA, 16),
.clk_pin = GPIO_PIN(PA, 17),
.miso_mux = GPIO_MUX_C,
.mosi_mux = GPIO_MUX_C,
.clk_mux = GPIO_MUX_C,
.miso_pad = SPI_PAD_MISO_3,
.mosi_pad = SPI_PAD_MOSI_0_SCK_1
}
in the driver params, I had this line for the SPI:
#define SX127X_PARAM_SPI (SPI_DEV(1))
Let us know if it works for you.
