For more information about the usb_config.c file, please refer to the MCHPFSUSB documentation available in the installation
found at www.microchip.com/mal.
There are two main steps to initializing the firmware. The first is to initialize the USB host stack. This is done via the
USBInitialize() function as seen below:
USBInitialize(0);
The second step that is required for the initialization is for the application to describe the accessory to the Android client
driver so that it can pass this information to the Android device when attached. This is done through the
AndroidAppStart
ANDROID_ACCESSORY_INFORMATION (
accessory. An example is seen below:
//Define all of my string information here
char
char
char
char
char
char
//Pack all of the strings and their lengths into an
//
ANDROID_ACCESSORY_INFORMATION myDeviceInfo =
{
};
int
{
Note that the AndroidAppStarter() function should be called before the Android device is attached. It is recommended
to call this function after initializing the USB Android client driver but before calling the USBTasks() function.
