Embedded Game Controller library

A static library for embedded devices to interact with Game Controllers over USB (and, in the future, bluetooth). When Embedded Game Controller is too long to write, you are welcome to use the EGC acronym.

Features

Supported USB game controllers

Device Name	Vendor Name	Vendor ID	Product ID
PlayStation 3 Controller	Sony Corp.	054c	0268
DualShock 4 [CUH-ZCT1x]	Sony Corp.	054c	05c4
DualShock 4 [CUH-ZCT2x]	Sony Corp.	054c	09cc
Generic PC controller	Dragonrise	0079	0006

• DS3 and DS4 support includes LEDs, rumble, and the accelerometer
• DS4's touchpad is used to emulate the Wiimote IR Camera pointer
• Both controllers emulate a Wiimote with the Nunchuk and Classic Controller extensions connected. Press L1+L3 to switch between them
• Three IR pointer emulation modes: direct (touchpad, only for DS4), analog axis relative (move the pointer with the right analog) and analog axis absolute (the pointer is moved proportionally to the right analog starting from the center). Press R1+R3 to switch between them

Supported target platforms

EGC can be built on the following platforms:

• Nintendo Wii
• Nintendo Wii's Starlet processor (cIOS)
• Linux with libusb

Compilation

Nintendo Wii

1) Install devkitPPC

• Download and install devkitPPC
• Make sure to install the devkitppc-cmake package when using pacman

3) Build libembedded-game-controller.a

1. mkdir build && cd build
2. Configure it with CMake:   cmake CMAKE_TOOLCHAIN_FILE="$DEVKITPRO/cmake/Wii.cmake" -DBUILD_EXAMPLE=ON ..
3. make (or ninja if configured with -G Ninja)
4. libembedded-game-controller.a will be generated

I recommend passing -DCMAKE_COLOR_DIAGNOSTICS:BOOL=TRUE, especially when using Ninja.

For the Wii's Starlet processor

1) Install devkitARM

• Download and install devkitARM
• Make sure to install the devkitarm-cmake package when using pacman

3) Build libembedded-game-controller.a

1. mkdir build && cd build
2. Configure it with CMake. Two options:
    a. arm-none-eabi-cmake ..
    b. cmake -DCMAKE_TOOLCHAIN_FILE:FILEPATH=$DEVKITPRO/cmake/devkitARM.cmake ..
3. make (or ninja if configured with -G Ninja)
4. libembedded-game-controller.a will be generated

I recommend passing -DCMAKE_COLOR_DIAGNOSTICS:BOOL=TRUE, especially when using Ninja.
