@brief I2C master bus specific configurations

Fields

i2c_port: i2c_port_num_t

< I2C port number, -1 for auto selecting

sda_io_num: gpio_num_t

< GPIO number of I2C SDA signal, pulled-up internally

scl_io_num: gpio_num_t

< GPIO number of I2C SCL signal, pulled-up internally

clk_source: i2c_clock_source_t

< Clock source of I2C master bus, channels in the same group must use the same clock source

glitch_ignore_cnt: u8

< If the glitch period on the line is less than this value, it can be filtered out, typically value is 7 (unit: I2C module clock cycle)

intr_priority: c_int

< I2C interrupt priority, if set to 0, driver will select the default priority (1,2,3).

trans_queue_depth: usize

< Depth of internal transfer queue, increase this value can support more transfers pending in the background, only valid in asynchronous transaction. (Typically max_device_num * per_transaction)

flags: i2c_master_bus_config_t__bindgen_ty_1

< I2C master config flags
