Communication PIC to PIC?

[peterdeco1]

Very crude but it works. A while back I had to send 1 of 8 numbers to a slave PIC. I used SOUND command on master & COUNT command on slave. First number was near 100HZ, 2 was 200HZ, etc. Worked perfectly. Count command was limited to 100ms and allowed fast response. Count command needs a "window" like IF PULSESRECEIVED > 8 and < 12 THEN LET X = 0. Hope this helps.

for your math you can't use float directly like that.

0.5 * x ===> still the same if you divide by 2

If x=1.5 ===> you should multiply by 10 then read IF x=15 depending of the previous math...

Well you should think integer than float.
