MSDTasks Function
C
BYTE MSDTasks();
Description

This function runs the MSD class state machines and all of its sub-systems. This function should be called periodically once the device is in the configured state in order to keep the MSD state machine going. 

Typical Usage:

Copy Code
void main(void)
{
    USBDeviceInit();
    while(1)
    {
        USBDeviceTasks();
        if((USBGetDeviceState() < CONFIGURED_STATE) ||
           (USBIsDeviceSuspended() == TRUE))
        {
            //Either the device is not configured or we are suspended
            //  so we don't want to do execute any application code
            continue;   //go back to the top of the while loop
        }
        else
        {
            //Keep the MSD state machine going
            MSDTasks();

            //Run application code.
