PIC18F2553 ADC and VREF
Posted: Sat Mar 30, 2019 7:30 pm
Hello Ben. I have the zipped patches in my FC7 file but still having an issue specifically with analog3 on the pic18f2553. I have a temp sensor connected to AN3, and I have a voltage emanating from the pin. The voltage should be .7v and it is actually around 3.5v
I'm not sure but it looks to me like the Vref pin is switched on and I have settings indicating it should be off. I have tried a few tricks but have not succeeded in getting rid of this voltage.
I have a jpeg of the details attachedm- Can you confirm that the FC7 is handling the vref stuff correctly for me?
