I have been trying to test the CubeCell on a Battery Monitor. I have GPIO5 set up as a trigger so at various points in the code I can trigger a high or a low in order to log the power usage and get an idea what is being used during the various cycles.
On starup I have
that works and I have confirmed that the trigger on the scope is low, Then at the start of the chosen routine I do a digitalWrite(GPIO6, HIGH);
The scope is set to start recording on the rising edge.
At the end of the routine I do a
This should trigger the scope to stop recording however GPIO6 is not going low.
I also tried this on GPIO5 and had the same issue.
it seems that once the GPIO goes high its it will not go low again.
Weirdly if i do put the scope on that pin I see it attempt to drop but quicly returns to 3.3v as if its being pulled back up.
