I can't believe there's nobody who can help me?
Does anybody think that the schema I posted is the solution for my task?
I want to control the motors via PC and via Buttons.
the buttons shuld by 4-position
- move motor clockwise
- move motor clockwise x-times
- move motor counterclockwise
- move motor counterclockwise x-times
and the comunication between the board with buttons and the board witch controls the motors should be thin, cause the limits of passage way of the cable tunnel.
therefor I thought the best will be to analyze the button position on the board with set of 4 buttons (each with 4-pos.) and put a PIC on the board.
otherwise i will be forced to lead 20-conductor cable trough the passage, and there no space for such thick cable.
all this is to control the windows on car.
I have PC inside and want to make them fully controlable...
when the PC is turned off to control them via buttons and when is turned on to control them via PC.
the doors are dismounted, and I want to close them next week....
therefor I ask you how many-conductor cable will I need for the communication between the board. take on mind the positions of button and the number of buttons. The thinner the cable, the better for me...
Please awnser me the "X-conductor cable question" before I mount the door, cause I will be forced to dismount them again...
