Bruce,
That's a great idea but... i'm not so familiar with those timer... For sure you can count with it... no problem with this part. The part i can't figure...

Let's say we want to count/sec... how to if F84a have only one timer module???

i can figure it easy with F628

1. timer0 to count input pulse
2. timer1 to get count/sec


but i figure we can do with F84a as follow

1. timer0 to count pulse
2. main loop must:
  • 1.display last counter value, as long 1 sec delay is not finished
    2.reload timer0 count to display
    3. redo main loop.

let's say we have 3 X 7 segments and we display on each about 5msec = 15 msec. this loop must be done 1Sec/15mSec = 66 times. I am wrong or close... i figure it make sense ...

regards
