Hi all.....I'm trying to interface an 8-bit ADC circuit to a proton development board via a I2C IC (PCF 8574P)....but all i'm getting on the LCD is 11111111 regardless of what the input is....i know for certain that the ADC works as i'm getting the correct value on the LCD when i connect the ADC directly to the proton board....i've checked to make sure the all appropriate pins have been grounded.....the proton board uses a 16F877A Pic....does anyone have any suggestions? thank you for your time.
