Given: 1. a reversing loop, isolated on both rails on each leg 2. current detection prior to entry of each leg 3. photo-detection at both sides of each isolation of the loop's legs 4. a DCC++ booster connected to the reversing loopas per David Bodnar design 5. A running program in the Pro Mini (attached): this uses current detection on its input at pin A0 to detect shorts and shut the booster. This program will need to be adapted to allow for the booster to change its phase (reversing polarity). This reversing will be made dependent upon detection of a train about to enter the loop. EDIT: pin 1: RPWM pin 2: LPWM pin 3: R_EN pin 4: L_EN pin 5: R_IS (right current sense) pin 6: L_IS pin 7: Vcc pin 8: GND Here is the schematic: Question: what needs to be changed on this wiring to get the DCC signal reversed?
