Hi,
This might be a out of way question, but still...... Actually few days back I saw a project which was a "Variable Constant Current Source" & the designer had controlled the Output Current value through PIC16F877A. The analog circuit is connected with uC through three pins AN0, AN1 & RC1/T1OSI/CCP2. The system also detects shortciruiting of the output, for this i think he has used AN0 & AN1. And for controlling Output Current value he has produced analog voltage from RC1/T1OSI/CCP2. Is this possible? is it possible to generate a analog output voltage from RC1/T1OSI/CCP2 proportional to internal digital value.
Thanks a lot.
regards,
Garg
