I have some of these old foldable Palm keyboards and trying oconvert it into a "normal" USB-keyboard.
I allready "decoded" the keymatrix at the internal connectors
I now want to use a teensy board (because it's capable to be a USB device for the PC) to convert the key input-matrix tu standard keycode output at the USB port.
So every time to inputs are connected I have e "key pressed" event, which then should result in a keycode send to the usb output
So some questions came up (because I'm really new to HW programing):
- can I mix digital and analog pins for the matrix (e.g. A11 and D01 is keycode for "A", but D01 and D02 is keycode "B")?
-and is the teensy capable to send "keycodes" instead of letter? (with the teenyduino I have to choose a keyboard layout, when using it as a kbd emulation, but usually the OS defines the layout and the kbd istself delivers keycodes IIRC).
Pictures to follow..
