Hi,

Does the IDE and bootloader support a USB port that is directly attached to the PIC32 instead of a FTDI chip as on the UNO32 and MAX32 boards?

I am looking at using the UNO32 as a development platform and eventually develop my own variant of the design. But I would most certainly want to forgo the FTDI based USB interface. Except, would that break compatibility with the IDE and bootloader?

Thanks, Adi

As long as the PC sees it as a COMx port, it will work. (Assuming you got the hardware correct.)

If you want it to auto-reset, you need to connect (possibly through a cap) the DTR handshaking line.

You might look into the alternate bootloader contributed by Rich Testardi. https://github.com/chipKIT32/pic32-Arduino-USB-Bootloader
