Hardware Abstraction Layer
USB Core - software/LPCUSBLib/Drivers/USB/USB.h

Detailed Description

Hardware Abstraction Layer for LPC architecture.

Modules

 Hardware Abstraction Layer LPC17XX
 
 Hardware Abstraction Layer LPC18XX
 

Functions

void HAL_USBInit (uint8_t corenum)
 This function is called by void USB_Init(void) to do the initialization for chip's USB core. Normally, this function will do the following:
 
void HAL_USBDeInit (uint8_t corenum, uint8_t mode)
 This function usage is opposite to HAL_USBInit.
 
void HAL_EnableUSBInterrupt (uint8_t corenum)
 This function used to enable USB interrupt.
 
void HAL_DisableUSBInterrupt (uint8_t corenum)
 This function usage is opposite to HAL_EnableUSBInterrupt.
 
void HAL_USBConnect (uint8_t corenum, uint32_t con)
 This function is used in device mode to pull up resistor on USB pin D+ Normally, this function is called when every setup or initial are done.
 

Variables

uint8_t USBPortNum
 

Function Documentation

void HAL_DisableUSBInterrupt ( uint8_t  corenum)

This function usage is opposite to HAL_EnableUSBInterrupt.

Parameters
corenum: USB port number
Returns
Nothing
void HAL_EnableUSBInterrupt ( uint8_t  corenum)

This function used to enable USB interrupt.

Parameters
corenum: USB port number
Returns
Nothing
void HAL_USBConnect ( uint8_t  corenum,
uint32_t  con 
)

This function is used in device mode to pull up resistor on USB pin D+ Normally, this function is called when every setup or initial are done.

This function is used in device mode to pull up resistor on USB pin D+ Normally, this function is called when every setup or initial are done.

Parameters
corenum: USB port number
con: connect or disconect
Returns
Nothing
void HAL_USBDeInit ( uint8_t  corenum,
uint8_t  mode 
)

This function usage is opposite to HAL_USBInit.

Parameters
corenum: USB port number
mode: USB mode
Returns
Nothing
void HAL_USBInit ( uint8_t  corenum)

This function is called by void USB_Init(void) to do the initialization for chip's USB core. Normally, this function will do the following:

These macros used to declare a variable in a defined section (ex: USB RAM section).

  • Configure USB pins
  • Setup USB core clock
  • Call HAL_RESET to setup needed USB operating registers, set device address 0 if running device mode
    Parameters
    corenum: USB port number
    Returns
    Nothing
