Code:

int main(){      stdio_init_all();       // For printing to serial over USB       spi_init(SPI_PORT, 1000000);      spi_set_format(SPI_PORT, 8, SPI_CPOL_1 , SPI_CPHA_1, SPI_MSB_FIRST);      gpio_set_function(MISO, GPIO_FUNC_SPI);      gpio_set_function(SCLK, GPIO_FUNC_SPI);      gpio_set_function(MOSI, GPIO_FUNC_SPI);      gpio_set_function(CS, GPIO_FUNC_SPI);      spi_set_slave(SPI_PORT, true);      while(true)      {            uint8_t read_command[4];            spi_read_blocking(SPI_PORT, 0, read_command, 4);                                    printf("Data read: %c%c%c%c \r\n", read_command[0], read_command[1], read_command[2], read_command[3]);      }}
