Due:  End of Lab Session (11.11.2013)

Requirement:  Bread Board, Jump Wires, MSP430, LEDs, Keypad and work with your lab partner on the code

The goal of this assignment is to gain more experience programming MSP430 functionality in C-language, and practice using the integrated debugger in the CCS IDE.

Keypad & Represent with LEDs

Connect keypad to Port 1. Each time a key is pressed, the program has to recognize which key was pressed and represent its value in binary through Port 2 LEDs. The keypad needs to be decoded by scanning the four rows (or equivalently each of the four columns) looking for a button that is pressed (low signal). Your program only needs to behave properly when a single button is pushed. For details of keypad decoding, see the note slides.

Make sure that for keys:

A - D => Display correct binary representations
# = E => Pound Key will have the E-value
* = F => Asterisk Key will have the F-value
0 key => Lights up the zero-key LED as shown below

See how it works
