keyboard and mouse to the 4D display

[ninja]

I am solving a way to connect a keyboard and mouse to a 4D display. I have a GEN4-ULCD-43D-CLB. There is some mention on the 4D forum that it is possible, but nothing too concrete.

The 4D system does have tx/rx, but it also has an I2C MASTER. One possibility is to connect a PS/2 keyboard and a PS/2 mouse to a small Microchip MCU and connect it as a slave via I2C to the 4D system. I haven't tried connecting a USB keyboard and a USB mouse, and I think it won't be possible without a USB master circuit.
I am sending a PM.

I have self-developed an 8x8 keyboard with i2c interface. Let me know if you are interested.
