[B]oseji sent in his project about using the MSP430F2013 as a simple timer display. He uses a SN74HC595 as an i/o expander to two seven segment digital displays for displaying time. Two pushbuttons are provided for user interaction and for setting the timer. At the moment times can be set between 1minute to 3o minutes. His future enhancements include integrating an RTC for displaying time.
SourceCode
Schematic – Included in above schematic.
Update – [B]oseji was having problems with a lot of noise from the pushbutton. He came up with a way of debouncing the button in the forums. Also, code on his blog has been updated with this new feature. Thanks [B]oseji!
