Scheme of the ADC

Icône de l'outil pédagogique Scheme of the connection...

The ADC display is connected to the D port of the micro-controller, which is the only port represented on the scheme below.

 

 

Without entering into details, we can notice that the communication between the micro-controller and the display is operated by mean of a 7-wires bus.

This bus contains 4 data lines (D7,D6,D5,D4) and 3 control lines (E, RS, R/W).

A potentiometer allows to adjust the contrast of the display.
