USB_Stall()
Purpose
Stalls portions of the USB interface: The Endpoints to be stalled are configurable.
Synopsis
Void USB_Stall ( IN char cUSBEndpointStall );
Parameters
cUSBEndpointStall: Input parameter
Specifies which endpoints are to be stalled by this function. The other endpoints
remain in their previous state. This parameter can be the result of an OR operation
between the following values if several endpoints are to be disabled:
ENDPOINT_0
0x01
ENDPOINT_1_IN
0x02
ENDPOINT_2_IN
0x04
ENDPOINT_1_OUT 0x08
Return Codes
None.
Deactivated endpoints will have a STALLED status. If all endpoints are stalled, it will disconnect
the USB interface from the Host.
USB_UnStall()
Purpose
Unstalls portions of the USB interface: The Endpoints to be unstalled are configurable.
Synopsis
Void USB_UnStall ( IN char cUSBEndpointUnStall );
Parameters
cUSBEndpointUnStall: Input parameter
Specifies which endpoints are to be unstalled by this function. The other endpoints
remain in their previous state. This parameter can be the result of an OR operation
between the following values if several endpoints are to be disabled:
ENDPOINT_0
0x01
ENDPOINT_1_IN
0x02
ENDPOINT_2_IN
0x04
ENDPOINT_1_OUT
0x08
Return Codes
None.
All unstalled endpoints will have status = IDLE.
USB_IN_1()
Purpose
Send data to the Host through Endpoint 1 (BULK IN). When the buffer size is bigger
than the Maximum Packet Size (specified by the Descriptor string initialized in the
USB_Init() function), then the API will split the buffer into smaller blocks and transmit
it in pieces.
Synopsis
Void USB_IN_1 ( IN struct USB_t *pUSB );
struct
{
unsigned char *USBData,
unsigned int
USBLen
USB_RC
USBStatus
} USB_t;
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.
