Function Documentation
| int tmrStart | ( | unsigned char | tmr, |
| int | dly | ||
| ) |
start the timer tmr for dly centiseconds
Start a timer number tmr for dly/100 seconds.
There are 4 timers numbered from 0 to 3.
After starting a timer a function tmrGet() should be called to know whether it is over or not.
The timer should be over after dly/100 seconds.
