Does Debugger or Visual Micro use Timer0?

I have an arduino sketch that disables Timer0 and uses Timer1 for timing functions.  The sketch does not complete Setup (where the timers are swapped) properly unless I do not enable Timer1 interrupts and leave Timer0 interrupts enabled.

Does Visual Micro or the debugger depend on Timer0 and/or Timer1?

By default Visual Micro uses Hardware Serial which uses the timer.

You can switch over to softwareSerial if you have an FTDI cable or similar and 2 spare digital pins.

This article describes how to configure the project properties for SoftwareSerial

You do not need to include the SoftwareSerial lib in your sketch, Visual Micro will do that automatically.

Thank you.

I do have some FTDI serial devices available.  I will look at the link you provided and see if that will help.

Hi John,

Other users report it works okay. If you don't need break/pause then you only need 1 digital pin (RX). 

Please keep in mind that SoftwareSerial uses interrupts for receive, I am not sure about send but that means you have to use pin(s) that support interrupts.
