Самодельная клавиатура с интерфейсом ps/2. Собрана на Attiny2313A и сдвиговых регистрах 74HC595 и 74HC165.
Прошивка Attiny базируется на библиотеке ps2dev
Простое описание данных для протокола PS/2.
Если что-то не работает, попробуйте старую прошивку из моей же статьи на хабре: https://habr.com/ru/articles/693784/ Например, эмулятор PS/2 клавиатуры для Спектрума, почему-то, не заводится с последней версией прошивки, но, завелся с версией из статьи. Собирали на стриме здесь: https://www.youtube.com/watch?v=hVR3ve-gX_8
Прошивка компилируется средой Arduino IDE,
Прошивается с помощью progisp172 программатором через порт "РПрог" для программирования на плате клавиатуры,
Fuse-биты для Attiny2313A: Low: E2, High: DF, Ext: FF, Lock: FF
Имейте ввиду, клавиатура не настраивается под ваш PC или контроллер автоматически, придется играться с таймингами в исходнике.
Для PC используйте значения:
#define BYTEWAIT 1000
#define CLK_FULL 40
#define CLK_HALF 20
#define TIMEOUT 30Для работы с esp32 и библиотекой FabGL используйте
#define BYTEWAIT 500
#define CLK_FULL 10
#define CLK_HALF 5
#define TIMEOUT 50Parts

Questions
How big is the Keyb PCB?
It measures 174 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyb use?
115 parts, built around the ATTINY2313-20PU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Keyb KiCad files?
From the coprolitebbs/ps2-keyboard repository on GitHub, at the commit this page was made from: the board is hardware/kicad_project/keyb.kicad_pcb and its schematic hardware/kicad_project/Butts 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
