USB bus powered PIC32 issues ?

Started by Simon Clubley September 21, 2015
While we are talking about Microchip, has anyone tried using the
PIC32 as a USB bus powered device in your own circuits and did you
have any issues as result ?

It's on my todo list in the upcoming future, so I am trying to find
any possible issues upfront.

I've done some searching online but I keep hitting stuff for the PIC18
or even the PIC24 instead. I have not found anything explicit in the
versions of the PIC32 datasheets/reference manuals I have locally other
than to say bus powered operation is possible.

In case it matters, this is the PDIP based PIC32MX2xx range.

Thanks,

Simon.

DC is DC, so the only possible problem would be if the device doesn't conform to the negotiations expectations of the host. This can be a thing, but I've only seen it as a thing from the POV of the host. -- Les Cargill

Thanks. The negotiations should not be an issue on the device in question; I was just trying to make sure there aren't any physical level issues I'm not aware of.
