Migrating USB from 17xx to 18xx

james3434 — Thu, 02 Mar 2017 12:23:36 GMT

Hi,

We are considering migrating from a LPC1758 to LPC1827 and I am trying to find an example USB device project for the 18xx series, does such a thing exist?

All the examples I found seem to use the USB ROM API which doesn't seem suitable for us (we are not using a standard USB class).

Thanks

Hi Jeremy

Those examples are for the 17xx series, for which we already have a working solution. The 18xx USB peripheral looks to be very different so I don't think the demos are compatible (please correct me if I'm wrong).

Are there any similar demos available targeting the 18xx devices?

Thanks
