Hi Sven,I received the HP HIL identification modules now, and did a quick prototype. It
seems to work. With my HP9000/3xx systems it looks like BASIC/WS is only accepting
keycode set 1 (ITF Keyboard) but not the PC like Keycode set 3. Haven't tried
with with my PA-RISC 9000/715 yet.
My current code (which isn't really finished yet) is here:
I didn't receive the Arduino pro micro yet, so i used the ATmega 2560 Arduino
for now which doesn't fit into the original housing.
A converter with less hardware seems to be possible with STM32 and a software
HIL implementation. These uC's run up to 72MHz internal clock, which i think
would be sufficient to sample the HIL data in an Interrupt routine.
