Has anyone of you tried to use this nice 16 key touchpad?
I ordered a few samples, as I want to use them in my new home, mainly for selecting lighting “scenes” in different rooms.
Originally, the header pins are sticking out on the front side, making it difficult to integrate this in a flat surface.
On this unit, I have removed the plastic spacer and bent the pins up, so that they can be connected under the surface where it’s mounted.
You can see on the panel that it has SCL and SDO pins. Sounds good!
So, I want to connect this touchpad with 3 wires (incl. GND) to the room’s Particle (Photon). 5V power supply comes from the 5V power bus which runs through the rooms.
I have googled around and found a few interesting Arduino sketches to start from:
- Arduino forum: LINK
This link also contains the links to a datasheet.
- Tutorial: LINK
This guy has a Github repository for his project: LINK
- A very complicated (Israeli) approach: LINK
This guy has a story about several (contradictory) datasheets…
I want to try to port some of these approaches, but if someone has already developed some sketch or ported one, I’d like to try it out first…
