Function Documentation

CDC_Control_HS()

int8_t CDC_Control_HS ( uint8_t cmd, uint8_t * pbuf, uint16_t length )

static

Manage the CDC class requests.

Parameters

cmd	Command code
pbuf	Buffer containing command data (request parameters)
length	Number of data to be sent (in bytes)

Return values

Result

of the operation: USBD_OK if all operations are OK else USBD_FAIL

Definition at line 190 of file usbd_cdc_if.c.

CDC_DeInit_HS()

int8_t CDC_DeInit_HS ( void )

static

DeInitializes the CDC media low layer.

Parameters

None

Return values

USBD_OK

if all operations are OK else USBD_FAIL

Definition at line 175 of file usbd_cdc_if.c.

References g_usb_terminal_connected, and USBD_OK.

CDC_Init_HS()

int8_t CDC_Init_HS ( void )

static

Initializes the CDC media low layer over the USB HS IP.

Return values

USBD_OK

if all operations are OK else USBD_FAIL

Definition at line 160 of file usbd_cdc_if.c.

CDC_Receive_HS()

int8_t CDC_Receive_HS ( uint8_t * Buf, uint32_t * Len )

static

Data received over USB OUT endpoint are sent over CDC interface through this function.

Note

This function will issue a NAK packet on any OUT packet received on USB endpoint until exiting this function. If you exit this function before transfer is complete on CDC interface (ie. using DMA controller) it will result in receiving more data while previous ones are still not sent.

Parameters

Buf	Buffer of data to be received
Len	Number of data received (in bytes)

Return values

Result

of the operation: USBD_OK if all operations are OK else USBD_FAILL

CDC_TransmitCplt_HS()

int8_t CDC_TransmitCplt_HS ( uint8_t * Buf, uint32_t * Len, uint8_t epnum )

static

CDC_TransmitCplt_HS Data transmitted callback.

Note

This function is IN transfer complete callback used to inform user that the submitted Data is successfully sent over USB.

Parameters

Buf	Buffer of data to be received
Len	Number of data received (in bytes)

Return values

Result

of the operation: USBD_OK if all operations are OK else USBD_FAIL

Definition at line 313 of file usbd_cdc_if.c.

is_bootloader_cmd()

bool is_bootloader_cmd ( const uint8_t * b, uint32_t n )

static
