Hi.

This sample uses CY8CKIT-044.

I created a stopwatch timer using segmented LEDs.

The LED display is based on the sample in "TSoC CY8C4146LQI-S433 基板 7SEG LED サンプル ".

Start and stop of the stopwatch timer are judged by interrupt from SW2 of CY8CKIT-044.

The LED time is updated every 100 msec.

State Machine of the stopwatch timer is as shown in the figure.

#define STANBY_MODE     0   /* initial state 7SEG LED "0000" */

#define COUNT_STOP_MODE 1   /* Count stop */

#define COUNT_UP_MODE   2   /* Count up */

Thanks,

Asanuma
