Initialization and de-initializations functions.
===============================================================================
##### Initialization and de-initialization functions #####
===============================================================================
[..] This subsection provides a set of functions allowing to initialize and
de-initialize the USBx peripheral:
(+) User must implement hal_usb_msp_init() function in which he configures
all related peripherals resources (GPIO, DMA, IT and NVIC ).
(+) Call the function hal_usb_init() to configure the selected device with
the selected configuration:
(++) Data Size
(++) Clock Polarity
(++) Audio Frequency
(+) Call the function hal_usb_deinit() to restore the default configuration
of the selected USBx peripheral.
◆ hal_usb_deinit()
De-initialize the USB peripheral.
- Parameters
-
[in] | p_usb | Pointer to an USB handle which contains the configuration information for the specified USB module. |
- Return values
-
◆ hal_usb_init()
Initialize the USB according to the specified parameters in the usb_init_t and initialize the associated handle.
- Parameters
-
[in] | p_usb | Pointer to an USB handle which contains the configuration information for the specified USB module. |
- Return values
-
◆ hal_usb_msp_deinit()
De-initialize the USB MSP.
- Note
- This function should not be modified. When the callback is needed, the hal_usb_msp_deinit can be implemented in the user file.
- Parameters
-
[in] | p_usb | Pointer to an USB handle which contains the configuration information for the specified USB module. |
◆ hal_usb_msp_init()
Initialize the USB MSP.
- Note
- This function should not be modified. When the callback is needed, the hal_usb_msp_deinit can be implemented in the user file.
- Parameters
-
[in] | p_usb | Pointer to an USB handle which contains the configuration information for the specified USB module. |
