Flora: More than 8 capacitive buttons?

Post by MrJimmo »

Hi there.

Main Question:
I saw the Plush Game Controller project (https://learn.adafruit.com/plush-game-c ... r/overview) and that has all the features I want to leverage, except I want 16 'buttons'.

Any examples of using Flora with 16 (or more?) capacitive touch 'buttons'? Not sure if I will need more than 16, but if there's something that allows for arbitrary number, I'd pursue that angle.


The basics of the project:
Create a mostly flat, flexible remote control that will lay on the arm of a recliner. This is for someone with advanced Parkinson's and very limited hand movement.
It's why I want to stay capacitive with a flexible construction, as I think that's the best ergonomic option.

I have my design for button layout, functionality, and all the IR Remote code working in an unrelated project using ESP8266 (simple web-based remote, so no physical buttons in that case) and I'll be referring to the Flora TV-B Gone project for that piece of the puzzle if needed.

So I'm really just down to figuring out how to get more than 8 cap. touch spots wired up to the Flora.

I'm not stuck on using the Flora, but those 2 projects look like they cover all I'm looking for. I'm open to other suggestions, if something else is even easier.

Suggestions, comments much appreciated.

Thanks! :o)

This board has 12 capacitive touch pins: https://www.adafruit.com/product/1982
It connects to the processor via i2c and is addressable so you can have up to 4 of them on the bus. That would give you as many as 48 cap-touch pins.

Virtually all microcontroller boards (including the Flora) support i2c, so you have lots of options.

Awesome! That (I2C) will be something completely new for me to learn.

Thank you! :)
