Detailed Description

This file contains all the specific code for the usb_core example.

Contents

The code can be roughly broken down as follows:

• Configuration functions
  • VBus_Configure
  • PIO configurations in start of main
• Interrupt handlers
  • ISR_Vbus
• Callback functions
  • USBDCallbacks_RequestReceived
• The main function, which implements the program behaviour

int main

(

void

)

Initializes the system, connects the USB and waits indefinitely.
