chipKIT Project 5: Digital stopwatch on seven segment LED display
A stopwatch is a timepiece that measures the amount of time elapsed between the time when it is started and the time it is stopped. Stopwatch is useful in many activities, including sports, games, and cooking, for timing events. We are going to construct a digital stopwatch using the chipKIT Uno32 board and the SPI7SEGDISP8.56-1R display module. The stopwatch will have the time resolution of 1/10th of a second or 100 milliseconds, and maximum measurable interval of 99 minutes, after which the stopwatch rolls over to zero again. More details on the MAX7219-based serial seven segment display interface can be found here.
