I think I answered my own question by reading the ELECTRICAL CHARACTERISTICS in the data sheet... A minimum delta between the two is needed for the ADC to function properly (3.0 V) .. Thanks

Weird Problem with ADC

I am using a PIC 18LF2553 for a small project and am trying to sample a pressure sensor. My goal is to set -Vref to 2.0 V and Vdd at 3.0 V to increase my ADC resolution where I need it. I wrote a small piece of test code to test if my hardware is right and I have a weird problem. I am doing three 12...

Just wondering one thing, my interrupt routine will only execute like once in three days just to read which mode i want it to be in. That is why it did not matter how long it was. That routine pretty much terminates whatever other subroutine the pic is in and changes which subroutine it gets stuck i...

Will do.. I added the little led part to see if i ever even get into the interrupt. the delay and everything was just a test. I sent it one byte to see if i got that led to blink, notifying me of the jump, but i will read that article you wrote and see if I can get it to work. The timer registers ar...

need help with interrupt

Can someone please help me with this simple Rx data interrupt. I cannot get it to work no matter what I do. I am using a 18f2553 with a microchip USB bootloader. I have tried it without the bootloader and it still does not work. The code will not jump into this ISR. I have all the variables defined,...
