Good morning.
I ´m working with nrf51-dk, sdk 9.0.0 and softdevice 110.
I have done a proyect without softdevice, only uart and master spi (mode 0) and works perfect.
Here code of the spi_init
void spi_master_inicio(void){
spi_master_config_t configuracion_SPI = SPI_MASTER_INIT_DEFAULT;
//Configuramos SPI
configuracion_SPI.SPI_Freq = SPI_FREQUENCY_FREQUENCY_K125;
configuracion_SPI.SPI_Pin_SCK = pin_clk; //12
configuracion_SPI.SPI_Pin_MISO = pin_miso; //17
configuracion_SPI.SPI_Pin_MOSI = pin_mosi; //15
configuracion_SPI.SPI_Pin_SS = pin_ss; //20
//modo 0
configuracion_SPI.SPI_CONFIG_CPOL = SPI_CONFIG_CPOL_ActiveHigh; // 0
configuracion_SPI.SPI_CONFIG_CPHA = SPI_CONFIG_CPHA_Leading; // 0
configuracion_SPI.SPI_CONFIG_ORDER = SPI_CONFIG_ORDER_MsbFirst;
//Inicializa la comunicacion SPI
uint32_t err_code = spi_master_open(SPI_MASTER_0, &configuracion_SPI);
if (err_code != NRF_SUCCESS){
printf("Error al abrir la conexion \n\r");
}
//Registramos el controlador de eventos relacionado con la comunicacion SPI
spi_master_evt_handler_reg(SPI_MASTER_0, controlador_evento_SPI);
}
The problem is when I add the spi to a BLE proyect, with pins (12, 17, 15, 20) doesn´t work but if I change pins to (1, 3, 5, 6) works, but i can´t use this pins because I use the analog pins to the accelerometer.
I read this, this and lf similar posts in forum, but i don´t understand why with ones pins works and with others no. My question is if softdevice has some pins blocks, i read "S110 SoftDevice Specification v2.0" and says that application has full access.
Thank you.
