Examples of using interrupts in Kreyos Meteor
This is how to set up and use interrupts for each of the four buttons, as well as pin P1.2, used for receiving serial communication.
The buttons toggle the backlight on and off, and the P1.2 interrupt copies P1.2 state, for rising and falling edges, to P1.1, thereby acting as a serial port echo, working up to about 19200 bps.
