Hello everyone, I am trying to figure out how to use the Touch Pads on the MSP430F5529 micro-controller to get the user to set time, The problem Statement is as Follows:
When the program starts, it will start displaying time starting from 00:00:00.
Pressing touch sensitive PAD4 causes the program to enter time adjustment mode, and while in time adjustment mode:
- Seconds will be immediately set to zero
- Touching PAD1 increases the hours (from 0 to 23, and then back to zero again)
- Touching PAD2 increases the minutes (from 0 to 59, and then back to 0 again)
- Touching PAD4 again will cause the program to run normally, displaying the current time that was entered by the user.

Any Help is greatly appreciated.
