daemonik Posted November 19, 2010 Report Share Posted November 19, 2010 Just finished my first MIDIBOX: a CV Interface with AOUT_NG Module During testing and troubleshooting I may have applied 12V to J5-A6 output-Pin = Gate-Out7 accidentally this pin now outputs 4.85V constantly, also after reloading of the application and MIOS damn... this make me think that the output circuitry of thr respective pin has been blasted!!! is this the likely reason for the unusual output? any chance to fix?? do I need to replace the PIC? All Gate-Outs are connected to +IN of Quad-OpAmps to gain the Gate-Signals to 10V; 2 pos-INs are adjacent to the Vd which is fed by 12V. blast may have occurred through shortening when I probed this IN Could I avoid another blast by putting a resistor between the PIC-OUT-Pin and the OpAmp-In??? and how much ohms should I choose? thanks very much Quote Link to comment Share on other sites More sharing options...
