An MSP430 Based Clock

Recommended Posts

impleAvr alerted us about his simple MSP430 based clock. The clock uses a MSP430G2231 controller which comes packaged with the LaunchPad. Since the 4 digit 7 Segment display needs a total of 32 lines for control and the controller has only 10 lines, he uses multiplexing to turn on required segments. Taking advantage of our persistence of vision or POV, the code cheats our eyes in seeing the full time.
