NEW PRODUCT! E1115 PS/2 Keyboard to TTL Serial Converter
NEW PRODUCT! E1115 PS/2 Keyboard to TTL Serial Converter – The E1115 PS/2 Keyboard to ASCII Converter is a single chip solution dedicated to producing a single TTL ASCII character on the “press” of a keystroke. It is designed to offload the process intensive complex keyboard decoding of PS/2, allowing the host microcontroller to better allocate its resources. The output is a selectable TTL serial or a clocked serial data with interrupt signal.
Plug in a PS/2 Keyboard in one end, and you can type away, with 57.6K or 115.2Kbaud (pin-selectable) TTL spit out of the TX pin. This can make adding a UI much easier for many projects where you can’t sit around and wait for the interrupts from the keyboard port. Please note that we’ve tested it and it works great with our PS/2 keyboard but it does not work with our PS/2 Magstripe reader or the PS/2 Touchpad.
Comes as a ready-to-go pre-soldered and tested module.

So, I was thinking about a very small serial terminal, like a vt100/220 small board/sheild type product. I don’t know enough on how to do it. But it would…
have Serial/console out to, say, a raspberry pi. It would have a single USB power in, it would have either a usb for the keyboard or a PS/2 connector. it would have a simple VGA out to hook up to a monitor. Oh, and it would cost about $29.
Where, oh, where could a hacker be that could make such a device. I know where to sell it, AdaFruit!
“Other control keys such as Alt, Ctrl, NumLock, and ScrollLock have no effect on the keys although outputs are produced.”
When will these keys be implemented?
Graham from Ditital-DIY.COM made his own using the free program Swordfish Basic and probably less than a $2 Microchip Pic.
“It looks like he is using a 18F2520 microchip, but you could use any 18F PIC”. I’m wondering if you can get CTRL functionality with his chip. All you really need is a Pikit 2 or Pikit 3 to program a Pic and there is a cheap version of the Pikit 2 being sold.
