Some help on touch sensors PLZ!

Hello everybody

Happy new year first of all

I have finished my LC with the PANASONIC MF’s

The problem: I need touch sensors. But I am no sure for the connection. The one pin of the switch will end up in the last DINX4 but the other pin sould it be ground or +5v?

Maybe I am totaly wrong

So please advise

Since the touch function works by grounding when you touch it which gives a difference in potential, I would say, you have to connect them to ground. I don’t know about you should connect it over a resistor.

Please search the archives… I think I once have seen a post, concerning this.

the panasonic mf’s dont have a touch track, u need to use buttons connected as norm to din, then just set em as mios emulated touchtracks…

From lc_io_table.inc:

     ;; 16th shift register
      ;;      button                  LED
      db      ID_FADER_TOUCH_CHN1,      ID_IGNORE            ; (no LED supported by host)
      db      ID_FADER_TOUCH_CHN2,      ID_IGNORE            ; (no LED supported by host)
