LCD_C, 4-Mux example, display a string "123456" on LCD if breakpoint. Displays "Ue9A68" if program is run all the way. This examples shows how to config LCD in 4-Mux mode with DriverLib functions. The internal voltage is sourced to v2 through v4 and v5 is connected to ground. Charge pump is enabled.

It uses LCD pin L0~L21 and L26~L43 as segment pins. f(LCD) = 32768Hz/((1+1)*2^4) = 1024Hz, ACLK = ~32768Hz, MCLK = SMCLK = default DCODIV ~1MHz.

This example uses the following peripherals and I/O signals on MSP-EXP430FR6989. You must review these and change as needed for your own board:

• LCD
• GPIO Port peripheral (for LCD pins)
