Simulation RA4

Hi,
I want to know why in the simulation if I sent:

output_A(0b111111);

Proteus simulation gives me high impedance in the pin RA4.

The silly thing is that the basic analog simulator on Proteus is very good. Where is has problems is in complex digital parts. Simple things like a transistor output, it'll usually get right.

There is a separate issue, down to how you use it, that it will automatically make connections to things like power pins, and then not show these. If you look at their examples, they deliberately put labelled pins showing these connections, while 'casual' users tend to omit these. Hence people following the circuit that results then omit these connections.

For what most people want a simulator for, it's digital handling of parts like the PIC's, is 'inadequate'. MPLAB is far more accurate, but harder to use.

I hate it, and believe it causes more problems than it ever solves, but don't expect basic things like this to not work.

Best Wishes
