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