Embedding WEFT in a Project
OK, so where do we go from here?
I’ve made the WEFT UI Board intentionally easy to repurpose—the OLED, encoder, and breakout board are intentionally not-impossible to remove. Once you’ve found a project that you want to permanently embed WEFT into, feel free to disassemble it and embed the DRV2667 board into something permanent.
For permanent installation, it’s prudent to use as little power as possible. The library’s
setTimeoutPeriod method puts the DRV2667 into low-power mode after a little while, and
sendToStandby immediately goes to the lowest-possible power use. You can wake it up with
wakeFromStandby. You may save even more power by only turning on the DRV2667 when your application is sure that someone is touching the electrode; I’d love to spend some remaining workshop time, if any, experimenting with ways to multiplex a capsense input to the electrode somehow (possibly by using the ground pad as a capsense pin?).
I’m sorry I forgot to add mounting holes!
