[riot-devel] Release 2018.04 planning

[Kaspar Schleiser]

Hey fellow RIOTers,

here are the dates for release 2018.04:

- feature freeze for high impact features will be on the 02.04.2018
- final feature freeze will be two weeks later, on the 16.04.2018
- final release date will be once all tests run through successfully

Happy hacking!
Kaspar

Re: [riot-devel] SPI on Arduino Zero for AT86RF233

[Tobias Guggemos]

Hey,

thanks, GPIO_MUX_C was the missing puzzle.

There is still a bug when receiving frames, but at least I can now initialize 
it correctly.

Thanks

Tobias

Betreff: Re: [riot-devel] SPI on Arduino Zero for AT86RF233

 

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  = >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.

Hey,

I’m trying to use the AT86RF233 with the Arduino M0 Pro (using the Arduino Zero 
configuration).

Using the default SPI configuration (and pins) didn’t 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 didn’t 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  = >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  = >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
#define AT86RF2XX_PARAM_SPI_CLK (SPI_CLK_5MHZ)
#endif
#ifndef AT86RF2XX_PARAM_CS
#define AT86RF2XX_PARAM_CS  ARDUINO_PIN_10
#endif
#ifndef AT86RF2XX_PARAM_INT
#define AT86RF2XX_PARAM_INT ARDUINO_PIN_7
#endif
#ifndef AT86RF2XX_PARAM_SLEEP
#define AT86RF2XX_PARAM_SLEEP   ARDUINO_PIN_8
#endif
#ifndef AT86RF2XX_PARAM_RESET
#define AT86RF2XX_PARAM_RESET   ARDUINO_PIN_9
#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, \
 .reset_pin = AT86RF2XX_PARAM_RESET}

 

Thanks 

Tobias
