Hey,
Im trying to use the AT86RF233 with the Arduino M0 Pro (using the Arduino
Zero configuration).
Using the default SPI configuration (and pins) didnt work, why I tried to
change the SPI to the Arduino_Pins 11,12,13 in order to have CS (PIN 10)
using the same SERCOM as the other SPI pins.
However, I didnt get it to work and it seems that using SPI with SERCOM1
does not initialize.
Is there anything I did completely wrong or is it just a stupid idea to
connect the AT86RF233 with an Arduino M0?
SPI Config in arduino/periph_conf.h:
static const spi_conf_t spi_config[] = {
{
.dev = &SERCOM4->SPI,
.miso_pin = ARDUINO_PIN_ICSP_MISO,
.mosi_pin = ARUDINO_PIN_ICSP_MOSI,
.clk_pin = ARUDINO_PIN_ICSP_CLK,
.miso_mux = GPIO_MUX_D,
.mosi_mux = GPIO_MUX_D,
.clk_mux = GPIO_MUX_D,
.miso_pad = SPI_PAD_MISO_0,
.mosi_pad = SPI_PAD_MOSI_2_SCK_3
}
,
{
.dev = &SERCOM1->SPI,
.miso_pin = ARDUINO_PIN_12,
.mosi_pin = ARDUINO_PIN_11,
.clk_pin = ARDUINO_PIN_13,
.miso_mux = GPIO_MUX_D,
.mosi_mux = GPIO_MUX_D,
.clk_mux = GPIO_MUX_D,
.miso_pad = SPI_PAD_MISO_3,
.mosi_pad = SPI_PAD_MOSI_0_SCK_1
}
};
at86rf2xx_params.h:
#ifndef AT86RF2XX_PARAM_SPI
#define AT86RF2XX_PARAM_SPI (SPI_DEV(1))
#endif
#ifndef AT86RF2XX_PARAM_SPI_CLK

#ifndef AT86RF2XX_PARAM_RESET

#endif
#define AT86RF2XX_PARAMS_BOARD {.spi = AT86RF2XX_PARAM_SPI, \
.spi_clk = AT86RF2XX_PARAM_SPI_CLK, \
.cs_pin = AT86RF2XX_PARAM_CS, \
.int_pin = AT86RF2XX_PARAM_INT, \
.sleep_pin = AT86RF2XX_PARAM_SLEEP, \
