Notes

• For Arduino Leonardo boards (authentic or clones)
• Does not require external power to the Arduino board
• Modified for 1000Hz polling rate
• Supports HID (default) and Reactive light control
• leoo supports up to 9 buttons (pop'n music, DanceDanceRevolution, and StepMania)
• leovxhq supports up to 7 buttons and 2 high-quality (50+ ppr/pulses per revolution) encoders (SOUND VOLTEX and K-Shoot MANIA)
• This is a personal fork; see the main iivx project for more use-cases, information, and support
• Add system button or change code before uploading to change light control (see leoo.ino or leovxhq.ino)
• As of 2022, the main iivx project points at more up-to-date projects here, and these may be more appealing than this fork

How To Use

• Download the code archive and extract it
• Acquire Arduino IDE (must be version 1.6.8 or newer) and start it
• Select Arduino Leonardo as your board in Arduino IDE (Tools -> Board)
• Select the COM Port that your board is using (Tools -> Port)
• Select the sketch you want (File -> Open -> either iivx-master/leoo/leoo.ino or iivx-master/leovxhq/leovxhq.ino)
• Upload the sketch to your board (Sketch -> Upload)
• Disconnect the board from your computer and implement it into your controller
• Connect the completed controller to the computer being used for games
• Bind controls for the games you want to play

Assumptions

• One board for SOUND VOLTEX and/or K-Shoot MANIA with 7 buttons, 7 lights, and 2 encoders
• One board for DanceDanceRevolution and/or StepMania with no lights and only 4 panels/buttons (if lights or additional buttons are needed, follow the pins for pop'n music)
• One board for pop'n music with 9 buttons and lights

Tested On

• bemanitools 4.21 (SDVX 3 & 4, pop'n 23, DDR 2014)
• SpiceTools (a few releases in 2019; SDVX 3 & 4)
• StepMania 5 (DDR pad)

Pins

• There are 3 separate GND pins that all function as ground
• All Buttons share a GND pin
• All Lights share a GND pin
• Lights require resistors, and some pre-assembled arcade button kits come with resistors soldered on already (check inside plastic light housing)
