3 Design Steps

  1. Configure the controller and peripheral I2C instance, GPIO pins, GPIO switches, and GPIO LEDs in SysConfig.
  2. Set I2C clock speed in SysConfig. Default is 400kHz for LaunchPad™ development kits with external pullups.
  3. Define the required I2C packet for proper communication.
  4. Create a demonstration that toggles IO expander outputs and an input from a switch that toggles an LED on the controller.
