PWM using PCA in AT89C51CC01

you first have to know how ADC works..

you can get some basic information about ADC here:
http://www.8051projects.net/adc-interfacing/introduction.php

Now ADC converts analog to an equivalent digital value. This digital value is measure of steps taken by ADC to reach that analog level. each step of adc provides the resolution of that ADC. if ADC is an 8-bit resolution so it has 255 steps, 10bit ADC h... Read Compelte post

MAX192 ADC schematics?

well ..
it is generally preferred not to connect VREF to VDD.

mostly in case of sensitive ADC application u either use two separate power supplies... for Analog and digital sections or simply isolate digital ground from analog ground.

but if it is just an experiment... just add a variable resistor/pot (small value) between VDD and Vref.
u are also supposed to add a zero ohm impedance between your... Read Compelte post

MAX192 ADC schematics?

I'm using a Dallas 8051 (DS89C450) for my microcontroller project and it's working fine with serial and a LCD, but now I want to add a MAX192 seriel ADC to it. I have a rough idea of how to write the software for it, but I'm not sure on how to connect it to my board. (I'm a programmer, not an electrical engineer )

At the moment I use Port1 for the LCD and three pins on P3 to control the LCD. Port ... Read Compelte post
