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
