Arduino Board as HP-IL device?

Finally here is a stable “sketch” version for the Arduino Mega -> “IL Drive Emulator”

The transfer speed is around 1050 Byte/s with a HP71. (Or around 700 Byte/s with a HP75)

Other goodie :-)
It’s possible to change dynamically the current lif/dat file on the sd card. You just have to send this IL commands:
“UNL LAD01 DDL0B UNL” on a IL controller.

For example with a HP71: “: “SEND UNL LISTEN 1 DDL 11 UNL” – this will take the next file in the directory. So, your SD card can be loaded with hundreds of LIF files.

Perhaps you might consider implementing some device dependant commands to list the images on the media and also select an image by name.
