Figure 5-1 shows the main function code for the IO expander. The main function initializes the peripherals and then enters a loop to handle received I2C communication.
Figure 5-2 shows the main function code for the controller. The main function initializes the peripherals, sends the I2C command to set the IO direction, and enters a loop that toggles the output pins on the IO expander.
