Although I do agree that the direct USB to PS/2 in the 6 or 12 pin configuration Pmod would be pretty cool to have.
Thanks,
JColvinHi JC,
Ever given any more thought to this idea?
PS/2 keyboards are becoming ever-increasingly difficult to find new.
It would be great to be able to plug a new USB keyboard in to a PMOD and just treat it as a PS/2 model from my code.
Alternatively, would you consider releasing the PIC24 code you used on the NEXYS 3/4 boards to do the USB>PS/2 conversion so that users could build their own without having to re-invent the wheel?
Best Wishes,
Leslie

Hi Kaitlyn,
If I understand correctly, you want to use the Nexys 4 or 3 USB port with PS2 signals.
No, my request has nothing to do with the Nexys3 or 4, I don't have either.
I would like to see a PMOD board which takes a USB Keyboard/mouse input, and converts that to PS/2 compatible signals on the normal 6/12 PMOD style header pins.
Basically, the same USB HID circuitry which already appears on the NEXYS3/4 boards, but on a PMOD board. Shouldn't be too difficult.
I would like to be able to use a USB Mouse/Keyboard on other PMOD equipped FPGA boards which *don't* have the USB HID circuitry. Nexys2 for example.
Hope that's a bit clearer
Cheers,
Leslie

Hi JC,
Thanks for your response.
Sorry, should have been more specific.
I was thinking of a PMOD board which basically incorporates the USB HID circuitry as implemented on the NEXYS 3 and 4 boards with a PIC24FJ192 .
>Are you wanting to use the older PS/2 communication style rather than trying to work with USB
Exactly. There is a great deal of code projects out there written to take PS/2 Mouse/Keyboard signals.
Such a PMOD board would allow those projects to be used "as-is" without having to implement USB in the FPGA.
Kind regards,
Leslie

Hi Digilent staff, and fellow forum members,
Just wondering if you guys had considered making a USB HID -> PS/2 PMOD board?
I was thinking of something like the circuit on the Nexys 3,4 boards which
uses a PIC to convert a USB keyboard to PS/2 compatible signals.Would be handy for using newer USB keyboards/mice on PMOD socket equipped FPGA boards.
PS/2 devices are becoming harder to find brand new.
I (for one) would be interested in a few.
Kind regards,
Leslie
USB HID -> PS/2 PMOD board ?
in Add-on Boards

Hi JC, et al.
Any progress on a USB HID PMOD board?
Surely I'm not the only one who would like to use a USB keyboard, but talk to it in PS/2 protocol on boards that don't have the PIC fitted.
You've already developed the firmware and circuitry using the PIC chip, so it shouldn't be too difficult?
Cheers,
Leslie
