Hi all,
I making a project wich uses a ADC0804 to read one resistive touch. Is working fine, but have one problema.
The resistive touch only suply in analog input 0v to 2.5v, but I reading only 0 to 80H (0 to 128), not 0 to 255, and this was complicating my conversion to prosition.
I haver leave the pin vref/2 NC. How i inform to ADC0804 wich is to last voltage is 2.5v and not 5v ?
Ty a lot
