Here at FRIB, we use a device named the "NetBurner" for communicating with I2C. Works well with a simple C program that allows a Telnet or HTTP connection on one side, and the I2C connection on the other.
Nice little product, but is short on memory.

Subject: Device Support for I2C and GPIO
Hey all,
for the adjustment and feedback loop of one of our power supplies, we need digital potenitometers and ADCs.
Both have a I2C interface. So our idea was to connect them to one I2C interface of a Beaglebone Black.
Does anyone have already a device support for I2C?
If not:
My idea would be to use the asyn package and write an asynPortDriver with an asynOctet interface, so one could use for instance streamDevice to implement the communication with the ADC or digipoti.
Also I have written a simple device support to use the GPIOs of a Beaglebone Black and Raspberry Pi via the /sys/class/gpio interface.
I would like to upload the sources to github. Is it possible to upload it to the "epics-modules" group?
Best regards,
Florian
