DC volts and A/D converter

I'am using a 16F877A for my project...and I need to get the DC voltage from and other circuit (0 to 100 volt dc). This voltage is use for my calculation and results are shown on display.

I have found schematic for voltage 0 to 5 volts. The idea is to bring the 0 to 100 volt to scale 0 to 5 ( only one scale, no pot or resistors with selector).

A schematic that ai heve found is
http://www.electronics-lab.com/proje...14/ilc7107.pdf

But i don' t need the display. I need to get voltage the same way but instead of the ilc7107 it would be with my 16f877a.

Can anyone help me with this.

guidance on pic micro controllers

Hi friends

I am very new to micro controller field, but I have experience in power electronics,

I want to gain practical knowledge in using micros for inverter applications, pls tell me how to start.

Using the above SEARCH function is a good way...maybe a search on POWER INVERTER.
Crazy ain't it?
