This board is for demonstrating how to use the Texas Instruments MSP430G2xxx microcontroller. The board has four pushbutton switches, four LEDs, two slide switches, two trimpots, +5V regulator for a 16x2 LCD, trimpot for LCD contrast, and backlight switch for LCD. It works with the MSP-EXP430G2ET Launchpad available from Texas Instruments for US $9.99 plus shipping. It also works with the now-obsolete MSP-EXP430G2 Launchpad.

It comes with software for:

Program 1 - Controls the LEDs. Displays a 4-bit binary counter.

Program 2 - Pushbutton switches control the corresponding LEDs. When the switch is pressed the LED is on. When the switch is released the LED is off.

Program 3 - Debounce the switches and toggle the respective LEDs

Program 4 - Debounce pushbutton switch pb1. When pb1 is pressed, roll the LEDs.

Program 5 - This shows why you need to debounce switches.

Program 6 - Demonstrate the 16x2 LCD including hex to BCD conversion

Program 7 - Reads Pot 1 and Pot 2 with the ADC (12-bit) and displays the hex values on the LCD.

Program 8 - Reads Pot 1 and Pot 2 with the ADC (12-bit) and displays the hex values on the LCD. Does some simple filtering.
