usbd core module
Function Documentation
| static int8_t CDC_Control_FS | ( | uint8_t | cmd, |
| uint8_t * | pbuf, | ||
| uint16_t | length | ||
| ) | [static] |
CDC_Control_FS 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 169 of file usbd_cdc_if.cpp.
| static int8_t CDC_DeInit_FS | ( | void | ) | [static] |
CDC_DeInit_FS DeInitializes the CDC media low layer.
- Parameters:
-
None
- Return values:
-
Result of the operation: USBD_OK if all operations are OK else USBD_FAIL
Definition at line 154 of file usbd_cdc_if.cpp.
| static int8_t CDC_Init_FS | ( | void | ) | [static] |
CDC_Init_FS Initializes the CDC media low layer over the FS USB IP.
- Parameters:
-
None
- Return values:
-
Result of the operation: USBD_OK if all operations are OK else USBD_FAIL
Definition at line 138 of file usbd_cdc_if.cpp.
| static int8_t CDC_Receive_FS | ( | uint8_t * | Buf, |
| uint32_t * | Len | ||
| ) | [static] |
CDC_Receive_FS Data received over USB OUT endpoint are sent over CDC interface through this function.
- Note:
- This function will block any OUT packet reception on USB endpoint untill 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_FAIL
Definition at line 250 of file usbd_cdc_if.cpp.
| uint8_t CDC_Transmit_FS | ( | uint8_t * | Buf, |
| uint16_t | Len | ||
| ) |
CDC_Transmit_FS Data send over USB IN endpoint are sent over CDC interface through this function.
- Note:
- Parameters:
-
Buf,: Buffer of data to be send Len,: Number of data to be send (in bytes)
- Return values:
-
Result of the operation: USBD_OK if all operations are OK else USBD_FAIL or USBD_BUSY
Definition at line 270 of file usbd_cdc_if.cpp.
