Use library without touch sensitive motor faders

[FabiB98]

Hi,
first of all: It is a fantastic library and I am very happy that I found it.
One question regarding the library: Is it possible to use this library without touch sensitive motor faders?
My existing ALPS faders do not have such an "Touch" pin.

Do you have any tipps for me how to proceed? Or would you suggest that I should buy new faders.
(However, I have already 16 faders, therefor I do not really like to throw them away....)

Thanks in advance!
Best regards
Fabian

If you use the latest version, you can set the touch_masks configuration option to all zeros:

Control-Surface-Motor-Fader/Motor-Controller/main.cpp

Line 143 in 7bcd5aa

static constexpr uint8_t touch_masks[] = {1 << PB0, 1 << PB1, 1 << PB2,

However, that's not enough: if the Arduino doesn't know that you're touching it, how does it know when to turn of the motor? In its current form, the software will just work against you when you try to move it, which kind of defeats the purpose.

You could add some logic to enable the controllers only when the reference changes, with some kind of lock-out system, and then detect when the user stops moving the fader by looking at the analog input.

Hi, thanks a lot for your reply!
I see the problem. I thought that there is an easy way to set the program to the above explained behavior.
I had a look to the code and I think that the re-programming expense is quite high.

Maybe I will shift around by introducing an additional push button for every fader. Using a D-FLIPFLOP I will produce a switch behaviour. If I set the Touch pin to VCC I can change the fader position by hand. After that I press the button again and then the PIN will set to LOW --> Motor fader is controlled by command.

Does this make sense for you?
Thanks a lot for your efforts!
