9.5 Timer Demo
This sample program simulates a darkroom timer. The board starts after reset flashing all LEDs.
After first key press of SW1, the board starts counting up expose times in unit of minutes (binary output
format). Pressing SW1 a second time selects the shown elapse time and starts the counting.
After the selected time is finished, the LEDs flash 20 times to display the elapse time and stop mode is
entered. Pressing SW1 releases stop mode.
To run the Timer demo please set the configuration of switch SW3 and connectors CN1, CN2 and
