Desk of Ladyada - I2C keyboards, encoders and potentiometers... oh my!
We're on a bit of a tear, playing with mechanical interface elements like mechanical keyswitches and now rotary encoders. This week we finished our 4-key I2C breakout, we had a yucky edge-case condition in our firmware where an GPIO IRQ could come in while we were handling one already, which caused a lockup. We also finished a very old project to make an I2C rotary encoder, while we were in the seesaw code we extended the code to support up to 16 encoders on arbitrary pins, we're planning on making a 4-encoder I2C breakout with NeoPixels. We also got our prototypes back for some more…
