(Picbasic Pro Compiler) Distinct management of two servos per timer(s) of 12F675?

[Acetronics2]

Hi,

I have a big problem with your program ...

What is it intended to do ??? ( Which inputs give which Outputs ??? ) or explain what you try to drive.

Understand by that there's a problem related to input signals use ...

try to write it down clearly on a paper ... there's some " overkill " in your program ... and it can be much, much, much simplified ...

Hi Alan.
Thanks for your interest in my question.

This is a system used in RC sailing to control the genoa of a radio-controlled sailboat.

The sail is controlled by two winches.

The RC Transmitter has :
1) a three-position switch which determines the side on which the sail will be set (port or starboard).
If the switch is in the middle position, the two winches each take up a specific end-of-travel position to make it easier to move the sail from one side of the boat to the other.
2) A potentiometer that adjusts the tension of the sail's sheet.


Finally, a small configuration jumper allows 4 different winch positioning configurations depending on how the sheeting circuits have been designed in the boat.

A more detailed explanation can be found in the appendix.

Note: In fact, the logic of my programme seems OK and the different servo winch positions obtained are correct. I just have a little instability in the positioning of the servos, which 'wiggle' a bit.
