Software that enables you to create your own Arduino based beatmania IIDX controller.

• HID lighting support (that works with btools and ttools).
• GUI configuration tool.
• Multiple input methods (joystick, keyboard, mouse).

• An Arduino Leonardo (technically compatible with any ATmega32U4 based board, but only tested with a Leonardo).
• The Bounce2 library.

Because this code uses LUFA, the process of uploading is a bit more different.

1. Add https://github.com/CrazyRedMachine/Arduino-Lufa/raw/master/package_arduino-lufa_index.json as an Additional Board Manager URL (in File -> Preferences menu)
2. Install LUFA AVR Boards from the Board Manager
3. Select Arduino Leonardo (LUFA) as your board type
4. Hit Upload

NOTE: To upload new code, you need to press reset in the GUI or on your board when the IDE shows PORTS {COM1, COM6, } / {COM1, COM6, } => {} or something similar in the log. (to enable showing this, check File -> Preferences -> Show verbose output during: -> Upload)

Buttons:

• One terminal to GND and the other terminal to the corresponding pin.

LEDs:

• Positive terminal to corresponding pin.
• Negative terminal to GND.

Encoder:

• Connect the encoder's wires to the corresponding pins.
• Set ENCODER_PPR in iidx-controller/config.h to the PPR of your encoder.

Manufacturer name:

• By setting MF_NAME in iidx-controller/config.h, you can change the manufacturer name of your controller.
• You can change this to whatever you'd like, such as your name.

Info:

• Pinouts are available in iidx-controller/config.h, you can edit them there if necessary.
• Leonardo pinout (what the numbers in the codes pinout arrays mean) at the bottom of this page.
• Additional settings can be configured via the GUI, more info here

• Huge thanks to CrazyRedMachine for helping me out when I got stuck, and for their SoundVoltexIO repository.
• John Lluch's Timer interrupt based Encoder library
• The digitalWriteFast library
