Detailed Description
Function Documentation
◆ TEMPLATE_Control()
|
static |
TEMPLATE_Control Manage the CDC class requests.
- Parameters
-
Cmd Command code Buf Buffer containing command data (request parameters) Len 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 130 of file usbd_cdc_if_template.c.
◆ TEMPLATE_DeInit()
|
static |
TEMPLATE_DeInit 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 113 of file usbd_cdc_if_template.c.
◆ TEMPLATE_Init()
|
static |
TEMPLATE_Init Initializes 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 99 of file usbd_cdc_if_template.c.
◆ TEMPLATE_Receive()
|
static |
TEMPLATE_Receive 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 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
