A Teensy-powered firmware for a custom SDVX controller. Features include a HID lighting system for use with games that support it, reactive lighting that can be enabled, and optimized USB dataflow for faster response time. Can use any RGB LEDs that support the FastLed library, or single-color LEDs with direct write.

This program uses a modified set of the Teensy Core Libraries for 3.2. See the teensy lib repo.

There are a variety of options that can be manipulated both in the code and by using the controller itself.

By defining the DEBUG macro in sdvx.h the Teensy will send information over the emulated Serial. Use the Teensy toolchain to read the output.

All mappings are editable in sdvx.h. Changing the mappings according to the structure will edit all references. This allows the controller to also emulate an IIDX ASC with little modification.

Defining USE_FASTLED will enable the system to write the LED output to FastLED supported addressable LEDs. This allows you to define custom colors as well as use RGB output over HID where supported. (Note that this will require some modification of the HID report descriptors as well as setup of the FastLED library)

In addition to the compile time options, the controller can be switched to a reactive LED mode by pressing all four BT buttons and START. This sets the first bit on the EEPROM, so it holds over reboots. The button combo can be set by modifying sdvx.h.

The software is considered "feature-complete" however additional features should be added. This is the roadmap for development

• Better FastLED support
• More LED options, including dimming and RGB
• Dynamic setup (including automatic descriptor generation)
