#WII U DRIVER CONTROLLER CODE#
The gamepad is a HID device, a USB HID Report Descriptor must be written and stored in your code In our example, we need to use this function to handle two special requests, you'll see it later This makes sure your device and computer are in a "reset" state to start off.Ī request handler function must be implemented, even if you don't perform real actions in it, you must implement it yourself. It's almost a standard practice to fake disconnect, wait a few milliseconds, and reconnect to the computer, during starting the code. You must initialize V-USB, and then enable interrupts in the AVR Then your project must implement the some functions. Make sure that "usbdrv/usbdrv.h" is able to find "usbconfig.h", if it's not able to, use the use "-I" to your makefile or edit "usbdrv/usbdrv.h" to change the file path to "usbconfig.h" (to "./usbconfig.h")
Use "#include" statements to include "usbconfig.h" and then "usbdrv/usbdrv.h" Inside the folder "usbdrv", there is a "usbconfig-prototype.h", copy that file into your main project directory, and rename it to "usbconfig.h"Įdit "usbconfig.h", this will be explained in detail later In your project manager or makefile, include "usbdrv.c" and "usbdrvasm.S", such that the object file that's generated will become linked into your project Make sure you've defined the processor and clock speed correctly (V-USB only supports certain clock speeds)Ĭopy the folder "usbdrv" from the downloaded package into your project folder In my project source code, it's already included.

Please visit the download section of V-USB's website to obtain a copy of the latest version. The files provided by V-USB will be compiled into our program in order to create a USB device with our ATmega328P V-USB uses a set of hardware and some very special assembly programming techniques to bit-bang the non-return-to-zero (NRZ) binary code that USB uses to communicate.
"V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip." However, it does not have built-in USB, which is a problem that we are going to solve using V-USB.
This microcontroller has enough memory resources and a built-in TWI/I2C peripheral to accomplish our goals. For the microcontroller, we'll be using a ATmega328P.
