Arduino Board as HP-IL device?

[charger73]

Hi all

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.

This all with a standalone, batteries driven system..

Please see the attached source code and the schematic plan for this little project.

This makes a lot of fun, you have to try it :-)

Best regards
