CMM2 Waveshare board version 5.06.00RC2
The following program works correctly when used with COUNT 4 (pin 24) but fails when using the FAST COUNT pin (18)
pwm 1,stop
setpin 18,CIN ' the fast count pin
print pin(18)
pwm 1,1000,50
pause 10
print pin(18)
>RUN
8510
8520
' the 85xx is immaterial, it just keeps increment every time the program is run
' that is, the counter is not being reset by a new SETPIN 18,CIN statement
'- the count does not even clear after a power reset!
>RUN
8530
8540
' changing to use COUNT 4 pin (24)
pwm 1,stop
setpin 24,CIN '
print pin(24)
pwm 1,1000,50
pause 10
print pin(24)
>RUN
0
10
>RUN
0
10
' works as I would expect.
Firmware is 5.06.00RC2. Also tested on an E100 running 5.05.03 using COUNT on GPIO 34 and works fine there.
Doug.
Edit: Forgot to mention - using a link from PWM to COUNT input for the tests.

Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.
