Set Address Of USB Device In LPC1768

Naveed Ahmed

Hi,

i am working with USB Device. Please guide me how can i set the address of device in LPC1768. As i have read about the Set Address command of SIE. it consist of 8 bits. first 7 bits (0-6) have DEV_ADDR and Last Bit DEV_EN. According to the manual that The device will respond to packets for function address 0x00, endpoint 0 (default endpoint).

The main confusion is that 0x00 is default and used the endpoint0 but in my case i am using isochronous endpoints and used 6 and 7 physical endpoints.

Will Device remains same for the endpoint 0 (default endpoint) and isochronous endpoints in my case(6 and 7)? if not then how to calculate the address of USB Device.

Please guide me.
Thanks in advance.

    For setting the device address that was your question you can take a look into LPC17xx USB Driver that can be found by installing LPC1700_DFP in file c:\Keil\ARM\Pack\Keil\LPC1700_DFP\2.2.0\RTE_Driver\USBD_LPC17xx.c in function named USBD_DeviceSetAddress.
