Switch Interface/ Motor Controller for Auto Drivers Power Window Control

INTRODUCTION
This idea is for the automotive industry. It serves as a
switch interface / motor controller for the driver’s side
power window control.
Using a PIC12C508 and an external comparator, one
could monitor the switches and control the motor necessary
for the operation of the driver’s power window.
Three switch inputs are required: 1) UP, 2) DOWN,
3) EXPRESS. Two outputs are required: drive_down
and drive_up. One interrupt or exception input is
required:Q rotor_stalled. Very simply:
if up,
then drive;
if down,
then drive_down;
if express,
then drive_down till not_stalled.
