  1. # orbweaver
  3. This firmware is for a Razer Orbweaver Chroma keypad, modded to replace the stock MCU
  4. with an Elite Pi RP2040 microcontroller. Mod instructions can be found on [geekhack](https://geekhack.org/index.php?topic=119396.0).
  6. The firmware controls a 6x5 key matrix (4x5 keypad + 6 additional keys
  7. on the thumb pad and up to 4 additional keys added by user). It also controls a
  8. IS31FL3731 RGB Matrix controller (on the Chroma model) via I2C interface. This requires
  9. a single I2C Driver with 20 common anode RGB LEDs. I found that the I2C clock speed must
  10. be slowed down to 100 kHz for the IS31 chip to keep up (the default for RP2040 seems to
  11. be 400 kHz unless specified otherwise).  
  13. The default key map (layer 0) is a generic layer based on the original Razer defaults. 
  14. You can change or add layers as needed, and change static colors in keymap.c
  16. Many thanks to bomtarnes, Drashna, Dasky, sigprof, and casuanoob for helpful discussions
  17. and coding suggestions and snippets.
