Labcentre Proteus Simulation software question

Thanks. Do you know any way where I can provide a minimum 0.5V and then increment 1.22mV on top. I have tried a few ways but couldn't do it precisely.

You could use one of the 12-bit DAC's, which gives 1.221mV steps.

A second PIC in the the .dsn with a couple buttons to control it should work.

Here's an example that gives two 12-bit analog voltages using a DAC.
A Virtual Terminal is used to set the voltages.
