The remainder of postbag #32, which turned into a bit of an epic. The capacitive touch switch modules were so flaky, they kept me guessing for far too long.

How to turn on toggle mode in ttp226
I have done all possible connections, read data sheet many times, but nowhere toggle Is written.
Ttp226 has too many options to select, but how to use it in toggle Mode. I don't want to use arduino only to toggle output, which is working.

Please tell me that how to do jumper setting for on and off switch in
ttp226 ? like one touch light on and again touch light off
Thank you for the "Single Touch switch" heads up. Nice!! But my keypads work very well and don't have the holes soldered.
So, easy way to get solder out of plated through holes. Soldering iron on one side of the board, suck from the other side.
I'm looking for a capacitive touch switch that toggles between either 3 or 4 states with just one button. Any idea if this component exists or how to search it?
Another thing after some thinking about the C-coupling and those traces you mentioned-
these things may be made for mounting in a much more shielded environment than floating about -nakedin 'capacitive' air and hands! I NEED TO FIND YOUR UPDATE VIDEO(S)!I find that desoldering wick will suck it right out of those holes–another alternative–wet the solder and thump/slap the PCB to knock out the solder with inertia–may need tor heat after this to smooth.. Filled-in holes: Probably due to a solder-wave swipe?? I agree with the "BAD" verdict.
The TTP226 is really frustrating, it has some intense problems too.
Use solder wick instead of horrible sucker.
you are supposed to use the back for touch. That way the connections are pointing the right way when mounting in a box.
You have large western digits, not china digits
Maybe it needs a 3D printed spacer grid thing between all the buttons, so you get a bit of a raised edge and to isolate the buttons from each other. Ordered the one with 16 buttons just now. I'd like to control the Ikea Trafdi smart lights with it and a Pi Zero W. Should be fun. 🙂
Did you ever get hold of a TTP226? I would love to see your tests on that. I've just ordered a few from China and would be happy to post you one when they arrive in a thousand years (I'm in UK too). Also, I'm intrigued by the brief mention in this video about matrix mode, I'd love to see your investigations into that.
