i2c_master_config Struct Reference

Configuration structure for the I2C Master device.

This is the configuration structure for the I2C Master device. It is used as an argument for i2c_master_init to provide the desired configurations for the module. The structure should be initialized using the i2c_master_get_config_defaults.
