API details

Global variables/contants

Procedures

• usb_send_one_byte(byte in data)

  This procedure will send one byte, with the contend specified by the data input 
  parameter, normally not called by the end user
  
  

• usb_stall_ep0()

  No documentation found

• usb_prime_epx_out( byte in end_point, byte in size )

  No documentation found

• usb_send_empty_data_pkt()

  This procedure sends an empty USB packet, normally not called by the end user
  
  

• usb_send_status_ack()

  This procedure sends an USB acknowledge packet, normally not called by the end user
  
  

• usb_send_data_chunk()

  This procedure sends the content of the USB delivery buffer in the USB SIE
  
  

• usb_send_data(byte in endpoint, byte in data[], byte in byte_cnt, bit in is_new_sequence )

  This procedure will send the content of an array to the USB end point. The endpoint 
  input parameter contains the the enpoint number, data[] is the content to be send,
  byte_cnt the number of bytes to be send, and is_new_sequence determines if the data
  tranmission is starting with USB packet o (if set to true), otherwise the USB packet 
  is toggled before transmission.
  
  

• usb_configure_endpoints()

  This procedure will setup and initalize the USB endpoints, 
  normally not called by the end user
  
  

• usb_prime_ep0_out()

  No documentation found

Private

• _usb_copy_array_to_ram(word in dst, byte in data[], byte in num_bytes )

  Internal memory copy procedure
  This function copies the content from a source array towards the specified
  destination memory location. The function copies num_bytes bytes
