SetStallEP
void(*void USBD_HW_API::SetStallEP)(USBD_HANDLE_T hUsb, uint32_t EPNum)
Function to STALL selected USB endpoint.
Generates STALL signalling for requested endpoint.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number as per USB specification. ie. An EP1_IN is represented by 0x81
number.
Returns:
Nothing.
ClrStallEP
void(*void USBD_HW_API::ClrStallEP)(USBD_HANDLE_T hUsb, uint32_t EPNum)
Function to clear STALL state for the requested endpoint.
This function clears STALL state for the requested endpoint.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number as per USB specification. ie. An EP1_IN is represented by 0x81
number.
Returns:
Nothing.
SetTestMode
ErrorCode_t(*ErrorCode_t USBD_HW_API::SetTestMode)(USBD_HANDLE_T hUsb, uint8_t mode)
Function to set high speed USB device controller in requested test mode.
USB-IF requires the high speed device to be put in various test modes for electrical testing. This USB
device stack calls this function whenever it receives USB_REQUEST_CLEAR_FEATURE request for
USB_FEATURE_TEST_MODE. Users can put the device in test mode by directly calling this function.
Returns ERR_USBD_INVALID_REQ when device controller is full-speed only.
Parameters:
1. hUsb = Handle to the USB device stack.
2. mode = Test mode defined in USB 2.0 electrical testing specification.
Returns:
Returns ErrorCode_t type to indicate success or error condition.
Return values:
1. LPC_OK(0) = - On success
2. ERR_USBD_INVALID_REQ(0x00040001) = - Invalid test mode or Device controller is full-speed
only.
