 The callbacks implementation uses the Timer driver. To handle the change from 100 to 1000 ms, the timer period is changed and a new timer callback is used. The hex and binary values of the I/O expander pins are displayed as a printf message over the Universal Asynchronous Receiver and Transmitter (UART).
