no0ne / ps2pico Goto Github PK

Anyway we can get a clear schematic diagram showing all the connections and parts used.

For whatever reason I can't tell by your pictures the layout of the circuit.

Thank you

can i use the sparkfun bi directional logic converter for this project instead of the transistor/diode/resistor converter.

Hi,
I have a question - will the "ps2pico-XT.uf2" firmware work on this adapter with a logic converter board?

Hi.

I have assembled the ps2pico and have a question about it. I took the version which is for PS/2 Keyboards

I currently have the whole thing put together on a breadboard. It didn't work initially. After some tests, I figured out to remove the Zener diode between GPIO14 and Ground. The other one from GPIO17 to Ground is still in place.

After removing it, everything worked immediately. Now I'm concerned that I might face issues with overvoltage later on.

In the picture, you can see my wild setup. 😉
Inside the rectangle is the Zener diode from GPIO 17 to Ground, and where the arrow is pointing, I removed it.

On the VBUS, there is pretty much exactly 5 volts. If I measure GPIO 14 to Ground or even GPIO 17, it's 0.5?!?! Whether the Zener diode is connected or not. Maybe I'm doing something wrong or I assembled it incorrectly. The Zener diodes are 3.6V 5W.
When I place a 10K resistor between GPIO 14 and Ground, everything still works.

Should I just leave it or is something "wrong", even though it works without the diode?
Thanks in advance!
