USBStatus: Output parameter
Contains the current status of this transmission, one of the following:
USB_TX_PENDING: Transmission has started, but is not yet complete. On
either a successful completion or a termination due to error, the USBStatus will
change to one of the following:
USB_ACTIVE: Successful data transmission.
USB_SUSPENDED: The HOST has suspended the USB bus, retry later.
USB_STALLED: This Endpoint has been STALLED.
USB_RESET: The HOST has reset the USB bus, retry later.
Return Codes
None.
USB_IN_2()
Purpose
Send data to the Host through Endpoint 2 (INTERRUPT IN).
Synopsis
Void USB_IN_2 ( IN struct USB_t *pUSB );
Parameters
USBData: Input parameter
Specifies the pointer to the data to be transmitted to the Host.
USBLen: Input/Output parameter
On input, specifies the number of bytes to send to the Host. On output, specifies the
current number of bytes sent to the Host.
USBStatus: Output parameter
Contains the current status of this transmission, one of the following:
USB_TX_PENDING: Transmission has started, but is not yet completed. On
either a successful completion or a termination due to error, the USBStatus will
change to one of the following:
USB_ACTIVE: Successful data transmission.
USB_SUSPENDED: The HOST has suspended the USB bus, retry later.
USB_STALLED: This Endpoint has been STALLED.
USB_RESET: The HOST has reset the USB bus, retry later.
Return Codes
None.
USB_OUT_1()
Purpose
Receive a buffer from the Host through Endpoint 1 (BULK OUT). The data may be
received within several packets if the buffer size is greater or equal to the Maximum
Packet Size, specified by the Descriptor String initialized in USB_Init().
Synopsis
Void USB_OUT_2 ( IN struct USB_t *pUSB );
Parameters
USBData: Output parameter
Contains the bytes received from the Host.
USBLen: Input/Output parameter
On input, specifies the maximum number of bytes to receive from the Host. On
output, specifies the current number of bytes received from the Host.
USBStatus: Output parameter
Contains the current status of this reception, one of the following:
USB_RX_PENDING: Reception has started, but is not yet completed. On either
a successful completion or a termination due to error, the USBStatus will change
to one of the following:
USB_ACTIVE: Successful data reception.
USB_SUSPENDED: The HOST has suspended the USB bus, retry later.
USB_STALLED: This Endpoint has been STALLED.
USB_RESET: The HOST has reset the USB bus, retry later.
USB_ERR_OVERFLOW: The HOST has sent too much data.
