Detailed Description

SPI configuration structure.

This structure defines SPI mode, clock, data format, and other controller/peripheral options.

Field Documentation

spi_controller

bool spi_config::spi_controller

true for controller mode, false for peripheral

clock_mode

spi_sclk_mode_en spi_config::clock_mode

Clock polarity and phase configuration

xfer_mode

spi_xfer_mode_en spi_config::xfer_mode

Transfer mode (TX, RX, EEPROM read, etc.)

frame_size

uint32_t spi_config::frame_size

Frame size in bits (valid: 4 to 32)

toggle_peripheral_select

bool spi_config::toggle_peripheral_select

Toggle CS between frames

disable_peripheral_out

bool spi_config::disable_peripheral_out

Disable output in peripheral mode

spi_clk_freq_khz

uint32_t spi_config::spi_clk_freq_khz

Desired SPI clock in kHz

rx_sample_delay

uint32_t spi_config::rx_sample_delay

Delay (in cycles) before sampling RX data
