made somthing whit a arduino can do type abc etc not even working as good as your cool keyboard :) realy love it be cool if can use it like old acorn keyboards whit words under the keys hold button then 1 then prints PRINT for example
wich are the key specs of the microcontrolers you would need for this jobs? i was looking fowards to build one for high-performance gaming, but i couldn't find much information over how to build one, and i fear that the teensy wouldn't do it
As far as creating this project with another MCU, you'd need to make sure it has enough I/O pins to cover the columns and rows of the key-matrix. The MCU will also need to have a fast enough clock to bit-bang the PS/2 protocol. And the MCU should tolerate 5v logic (or at the very least, a logic level shifter for the PS/2 clock & data lines). At a glance, the Teensy 4.0 may work fine in this project so long as you have a logic level shifter from 3.3v to 5v and vice-versa between the MCU and Host.
Thanks, also@@HuffmanCS would a MCU like the AT90USB82 or AT90USB162 do the trick? in this case is specially to try to find a cheaper option to a tensy
Yes! As a matter of fact, the AT90USB82/162 MCU even contains built-in hardware to specifically help with implementing the PS/2 protocol. (Although I assume you're aware it is a SMD and contains the AVR architecture, so ensure you're equipped for that should you use it!)
Good effort... now, you could have had that easier: just exchange the USB plug for a PS/2 plug on the keyboard. Instructions for that can be found all over the internet.

Thank you so much, your video helped a lot to create your project and debug it!
Thanks for sharing…
keep continuing this
Good Job !!
Really good. I am waiting your new videos
I loved it and I'd love to continue seeing videos of your journey.
