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. -- Simon Clubley, clubley@remove_me.eisner.decus.org-Earth.UFP Microsoft: Bringing you 1980s technology to a 21st century world

This can be a thing, but I've only seen it as a thing from the POV of the host. -- Les Cargill

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.> This can be a thing, but I've only seen it as a thing from > the POV of the host. >Thanks, Simon. -- Simon Clubley, clubley@remove_me.eisner.decus.org-Earth.UFP Microsoft: Bringing you 1980s technology to a 21st century world
