I have created a GPIO component, and I have MQX-Lite running. I can use the GPIO APIs to set and clear the outputs. Now, if I try to enable events on a pin, it just says they aren't supported, yet the pins have keyboard interrupts attached to them. If I try to use the IRQ module, it only recognizes the port I pins. Is there a preferred way of using keyboard interrupts with MQX-Lite?
