# 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
|
||||
|
||||
Many thanks to bomtarnes, Drashna, Dasky, sigprof, and casuanoob for helpful discussions
|
||||
and coding suggestions and snippets.

|
||||
|
||||
## Bootloader
|
||||
|
||||
Enter the bootloader in 2 ways:
|
||||
|
||||
* Press and hold the upper left hand key on the main keyboard while you plug in the USB.
|
||||
* Press and release both reset buttons on the top of the RP2040 inside the modded unit.
