Hardware designs by Michael Schwingen, michael at schwingen dot org

This is a GPIB interface that is attached to the GPIO connector of a Raspberry Pi, using the Linux GPIB driver package.

It is similar to the existing elektronomikon Raspberry Pi GPIB Shield and other GPIB shields for the Raspberry Pi.

However, all existing designs I could find either directly connected the GPIB bus to the Raspberry Pi's GPIO pins, or used SN7516x bus drivers. Both may expose the GPIO pins to voltages that are higher than the allowed 3.3V - the risk may not be high, but I did not want this for reliable long-term operation.
