Hi all,
I want to interface the Arduino to an Amiga 500 keyboard. However, the question might be more general:
The Amiga's keyboard interface consits of Clock and Data lines, where a handshake signal is expected from the Arduino via Data. This probably means Data is bidirectional. Would it be a good approach to connect Data directly to an input line, and via diode and resistor to an output line from the Arduino?
I've thus far tried to use a single line, directly connected, switching from Input to Output state, and may have fried something (don't know). Anyway, it didn't work. My next try should be successful, if all has survided my attempts to kill it.
2nd: There's a hardware reference manual, mentioning Clock is an active low signal. Does this mean a '1' is represented by 0V and a '0' by 5V? Or did I got this completely wrong?
Please bear with a beginner :-).
Thanks,
