Touchpad TTP229 dummy value

#1 Post by Dick60 » 03 Nov 2018, 08:55

Still struggling getting my touchpad working. I created 2 divices:
1: device PPT229 touchpad called 'keypad', the value field is called 'ScanCode'

2: a virtual device called 'dumkeypad' , the value filed (the first one of the 4 available) is called 'Dumkeyfield'.

to copy the the value of the 'ScanCode' is done by a rule:

On keypad#ScanCode Do
If [keypad#ScanCode] = 1.00
TaskValueSet 2,1,[keypad#ScanCode]
If [keypad#ScanCode] = 5.00
TaskValueSet 2,1,[keypad#ScanCode]
Endif
Endon

But the value of the pushed button is visible in the value field ScanCode but not transferred to the Dummy field Dumkeyfield.

What is wrong?
Pls advise.

Hi Thomas, I used SCl GPIO16 and SDO GPIO14. i found out that the keypad works fine, with the latest rom but the rules do not work in the latest roms. I my opinion all should work with the rew release of the final of the upcomming Rom. I am prepared :D
