Stable ADC readings

[mazoul72]

Hello,
First many thanks to your answers .

OK, please answer the following question:

Q1: The Resistor attached to the button are built-in the remote/Steering and you can't modify anything in right?

A1:_Yes , it is too little inside because it is cms components .

Q2: You have a 10K pull-up On RA0, and another on RA1... true?

A2: Yes , it is an omission but it is 10Komhs for test ( 3.96 Volts with no action)

Q3: If so, assuming you don't push on any button, Between GND and RA0 AND between GND and RA1 with your multimeter you should read something like 1.4Volt RIGHT?

A3: No , i read 3.96 Volts on 10K resistors and RA0,RA1.

So , (3902/(3902+10000))*5 = 1.403 .
i will verify if there is another resistors but i see 3902 ohms (i am sure) , perhaps an error . I will tell you about.

I don't understand : TRISB = ((DCD i) << (ADCChannel*3)) ^255



Best regards
