Function Documentation

s32 MIOS32_USB_ForceDeviceMode ( void   ) 
Returns:
!= 0 if device mode is enforced in the bootloader config section
s32 MIOS32_USB_ForceSingleUSB ( void   ) 
Returns:
!= 0 if a single USB port has been forced in the bootloader config section
s32 MIOS32_USB_Init ( u32  mode  ) 

Initializes USB interface

Parameters:
[in] mode 
  • if 0, USB peripheral won't be initialized if this has already been done before
  • if 1, USB peripheral re-initialisation will be forced
  • if 2, USB peripheral re-initialisation will be forced, STM32 driver hooks won't be overwritten.
    This mode can be used for a local USB driver which installs it's own hooks during runtime.
    The application can switch back to MIOS32 drivers (e.g. MIOS32_USB_MIDI) by calling MIOS32_USB_Init(1)
Returns:
< 0 if initialisation failed
Note:
Applications shouldn't call this function directly, instead please use MIOS32_COM or MIOS32_MIDI layer functions

Here is the call graph for this function:

s32 MIOS32_USB_IsInitialized ( void   ) 

Allows to query, if the USB interface has already been initialized.
This function is used by the bootloader to avoid a reconnection, it isn't relevant for typical applications!

Returns:
1 if USB already initialized, 0 if not initialized
void OTG_FS_IRQHandler ( void   ) 

This function handles OTG_FS Handler.

Parameters:
None 
Return values:
None 
void USB_IRQHandler ( void   ) 

Interrupt handler for USB

Note:
Applications shouldn't call this function directly, instead please use MIOS32_COM or MIOS32_MIDI layer functions
void USB_LP_CAN1_RX0_IRQHandler ( void   ) 

Interrupt handler for USB

Note:
Applications shouldn't call this function directly, instead please use MIOS32_COM or MIOS32_MIDI layer functions
void USB_OTG_BSP_ConfigVBUS ( USB_OTG_CORE_HANDLE *  pdev  ) 

USB_OTG_BSP_ConfigVBUS Configures the IO for the Vbus and OverCurrent.

Parameters:
