Any strange behaviour, crashing issues etc, post them here! Problems compiling the firmware should go in the General support section rather than here

Hi,

among different issues I noticed bad behaviour of tachometer. Most of the time it works ok but sometimes needle goes down for short while then works ok for some time. It seems problem is more visible during acceleration mid-high rpm (above 3000). On high RPM like 5000-6000 it goes down to 0 and stays there. More duration more chance of problems,

So I started to make tests using ArduStim and oscilloscope and found tach out signal in unstable indeed when FIXED is used:
