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.

I have a proform too. So far all controls work but I'd be interest in adding an Rpi to handle the controls and broadcast power via Ant+ to interact with 3rd party training software. I will start poking around inside to see what I can find and report back.

Thanks kilomotor,
I would be very interested in the signals generated to the lower control board when you change the incline or shift the gears while in manual mode.
 
Hi - any assistance appreciated. I have a Proform Tour de France PFEVEX71516. After being switched off for 2 years the screen rolls between white and striped. It briefly loaded the software but now just loops. When first switched on it makes the start up noise.
