For further info, having downloaded the trail xc8 pro & built to hex using it (it took a while to get V7 running again, as soon as I tried to change the path in compiler options this just caused flowcode to ...

Re: Timing problems pic16f887

Hi, thanks for keeping going with this one!

Now I know how to set the intosc - thanks to the forum pointing me in the direction of the intosc helper tool! I've tried the 1on 1off programme at various frequencies, with the cycle time as follows:
31000hz = 4.03s
125000 hz = 2.44s
1000000hz = 2.06s ...

We've decided to drop from the original 4Mhz external timing crystal to a 32.768 KHz crystal as this reduced the quiescent current from 2.5mA to under 1mA. Having just copied the ...
