# Technomancy Atreus This is a plugin for [Kaleidoscope][fw], that adds hardware support for the [Atreus][atreus]. Supports both the pre- and post-2016 variants with an A* MCU, the hand-wired variant from [FalbaTech][falba] with a Teensy2, and the legacy teensy2 variant too. To select which one to build for, you can either use the Arduino IDE, and select the appropriate Pinout and CPU, or, if using `kaleidoscope-builder`, you can add a `LOCAL_CFLAGS` setting to your Makefile For the post-2016 variant (the default, also used by the handwired variant from FalbaTech), if you want to explicitly select it, add `-DKALEIDOSCOPE_HARDWARE_ATREUS_PINOUT_ASTAR=1`. For the pre-2016 variant, add `-DKALEIDOSCOPE_HARDWARE_ATREUS_PINOUT_ASTAR_DOWN`. For the legacy teensy2 variant, add `-DKALEIDOSCOPE_HARDWARE_ATREUS_PINOUT_LEGACY_TEENSY2=1`. To be able to flash the firmware, one will need the [Teensy Loader CLI][teensy_cli] tool in addition to Arduino, if using a Teensy. If using an A* MCU, the additional tool is not required.
