Field Documentation

ten_bit_addr

bool i2c_controller_config_t::ten_bit_addr

true = 10-bit addressing

speed

i2c_speed_en i2c_controller_config_t::speed

Bus speed

enable_bus_clear

bool i2c_controller_config_t::enable_bus_clear

Enable bus clear

clear_stuck_sda

bool i2c_controller_config_t::clear_stuck_sda

If SDA is detected as stuck automatically try and recover

scl_stuck_timeout_ms

uint32_t i2c_controller_config_t::scl_stuck_timeout_ms

SCL stuck-low timeout (loop count), set to 0 if not desired

sda_stuck_timeout_ms

uint32_t i2c_controller_config_t::sda_stuck_timeout_ms

SDA stuck-low timeout (loop count), set to 0 if not desired
