Detailed Description

USB driver for MIOS32

Uses LPCUSB driver from Bertrik Sikken (bertrik@sikken.nl) which is installed under $MIOS32_PATH/drivers/LPC17xx/usbstack -> http://sourceforge.net/projects/lpcusb

Applications shouldn't call these functions directly, instead please use MIOS32_COM or MIOS32_MIDI layer functions

Function Documentation

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

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 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
