Hello,
I have a Pro-Form Le Tour de France exercise bike. The console buttons have stopped working, and I have been unable to diagnose the issue. The console button matrix is decoded through a pair of hc165 parallel to serial shift registers. It appears that the clock input to these devices is only about 75mV. The clock signal comes from a Renasas R5F212DASNFP MCU. If I can't fix the console, my backup plan is to replace the console with a raspberry pi. Does anybody have any info on the interface to the control board? It needs to control the incline and the magnetic resistance of the flywheel.
