Writing custom USB HID EP0 handler for LPC1754

IanCraig — Mon, 18 Dec 2017 15:25:54 GMT

I'm currently coding a project using the LPC1754 that is required to interface to our existing host software that uses EP0 to send custom commands to the processor. To accomplish this I need to modify the existing HID EP0 handler.

Looking at the the USB driver in LPCOpen 2.10 this is only provided as a library and the existing documentation for this library has no detail on how to write custom handlers, the section on customisation has no detail only a placeholder of "TBD".

Is there updated documentation on how to do this or source code for the USB library available to guide me on how to write custom handlers.

Thanks

Hi,

Please refer the application note AN10866 software about USB EP0 control.

The AN10866 is LPC1700 secondary USB bootloader application.

More detailed info, please check here.

Wish it helps.

best regards,

Mike
