LPC55S69-EVK Simultaneous USB Host and Device

[ja2022]

Hello,

I have a question about this dev board and this microcontroller. What I would like to do, is have both a USB device and a USB host on one microcontroller, acting as a "proxy" for the USB device connected to the board.

The user manual mentions that either port can be configured as a host at once in section 6.1, but nothing on using one as a host and one as a device. Is this a possible thing to do with this platform? If not, where else should I look within NXP microcontrollers?

Thank you!

HI

Yes you can have both a USB device and a USB host on one microcontroller.

I suggest you setting different task priority on each task when created. You could take keyboard2mouse sdk example as reference.

Hope this helps,
