i want connect an ADC0804 output to my PIC18LF4620, the problem is, before connect to the PIC ports the voltage is 5V, but when i connect to PIC PORT, the voltage is 0v. why?? i'm suing two different board one is ADC0824 board another is PIC board, i had ground them together but with different VDD supply source.
