Hi Towlerg,

As I wrote, indeed, I think it would be better to do less in the low priority, but still, in theory, the problem remains, even when doing very little in the low prio interrupt. only...

As said before, you should indeed charge something. I am using with great pleasure your software and I think it is good for everybody that the software has a great future.

The diode is only to seperate the 5Volt part where some sensors and displays are attached from the 5Volt of the PIC..

This will be killed in my next test with the empty pcb..

This is good to hear. I will first make the transition to the 18F47k40 to make my life easy and when everything is in place, I will transfer to the Q-series.

I can imagine that all the work is...

I did not realise it is soo different but I am beginning to understnd that... That is for sure not what I am looking for at this moment :)
