Capacitive Touch Hypercube Keyboard
Capacitive touch keyboard designed to be integrated into Hypercube
- The touch chip to be used is TTP229. They can read 16 keys. Need at least 4 chips to encode the full keypad.
- Changing the design to add more keys is an option.
- Adding a USB serial is an option.
- The board will have serial, I2C and SPI interface.
- Connecting a real keyboard is always better - but at times there just isn't enough space to cram everything into one compact piece of technology.
- One Hypercube accommodate 12 boards, so if there is space, this keyboard is added as needed.
- This board is intended to be released in KiCAD under open source license along with all the multi-tasking software needed to drive it.
- Have a look here for example of working multi-tasking software
