Hi,
I have a problem getting some pins on the arduino Mega board I'm using to simply toggle on-off.
I set them as outputs and use the "SET" and "RESET" commands to toggle the pins.
But for some reason I get strange results on some of the pins and/or no output on some of them.
Here is the pins I have problem with, and their results from a quick test program I wrote to debug the issue:
PinB.4 Toggles every second loop.
PinH.6 Does not output (stays low).
PinH.5 Does not output (stays low).
PinH.4 Does not output (stays low).
PinH.3 Toggles fine.
PinG.5 Toggles every second loop
PinC.5 Does not output (stays low).
PinC.7 Toggles fine.
PinA.6 Does not output (stays low).
PinA.4 Does not output (stays low).
PinA.2 Does not output (stays low).
PinA.0 Toggles fine.
The program just toggles these pins every 1 second, so the result can be seen with some LEDs.
Any suggestions? I'm using Bascom 2.0.7.7
