This attempts to make it a bit easier by presenting the output in two arrays (buttons and axes). A maximum of 4 axes and 12 buttons is supported. +The opcode uses evdev so only works on Linux. + + +## Requirements + - Csound development libraries + - Cmake 3.8 or later + + +## Building +Create a build directory at the top of the source tree, execute *cmake ..*, *make* and optionally *make install* as root.
