All devices connected to the I

transmitter or slave receiver. Because the processors do not have I
controller on-chip, the I
GPIO controller (GPIO6 and GPIO7), and this component depends on functionality
provided by the GPIO driver.
The GPIO software driver is used to toggle two pins on the GPIO controller, which
represent the SDA and SCL lines of an I
