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 i have found is
**broken link removed**
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.
Tanks
