Re: Creating an RPM and Temp Sensor
My last post has not been approved yet, so I cannot edit but I am back with my findings. In my code I use both interrupt 0 and 1, because I measure ignition battery voltage with a frequency up to 2.2kHz. I had no problem measuring battery voltage and at the same time having an RPM of a little over 6...

Re: Creating an RPM and Temp Sensor
Hey there, I am reading the hall effect sensor of my DLE ignition for RPM via a optocoupler (which you would not need on a nitro), and that is working great. I have only tested it on the ground and up to 8800 revs, but I could easily hook up my function generator and try to bump it to 65000rpm to se...
