I am helping a guy with his Microsquirt, and we want to use the spare ADC's (6-7) for a sensor input ,but for some reason it will not read the full scale, ADC7 will read around 15, then when we start the motor it will read 1023 ( the input voltage does not change ) we have measured the input voltage on both sides of the input resistor and all looks fine.
ADC6 stays at 3 and never moves.
Its like the Processor has the two adc ports initialized to low or something.
I use the same setup on the Micro Module with no problems .
We have flashed both standard 2.89, and extra code with no luck, since i dont mess with the Microsquirt that much (I usually use the Module) im not sure if there is something im missing or what .
ADC7 and ADC6 problem

Re: ADC7 and ADC6 problem
The first thing to check is that you have a V2.0 board (green). Then you need to check the settings for knock and 2nd ego and baro correction because these are used on ADC6, 7 and if the settings conflict that could cause a problem. If you have and msq that works on the module with 2.89 code, then it should also work on microsquirt - they are electrically identical and the sw is identical.
