Experimental Physics and Industrial Control System

Hey Peter,
to access the GPIOs from EPICS you need to write a device support
module using the C-libraries.
Unfortunately there is no good documentation on this topic for
beginners that I know of...
I could provide you my device support for reading out DS18S20
Dallas-1-Wire Temperature sensors using the Pi as a starting
point.
Best regards,
Florian

Hello all...
We are exploring the idea of using Raspberry Pi for basic
digital IO tasks. The idea
is that we could avoid deploying other
IOCs and possibly wasting many other
IOC ports.
I have EPICS running on a Raspberry Pi with a test
record DB (soft records only) and it is successfully communicating
across the network. I know how to directly access the GPIO pins
while on the Pi (through C libraries etc.), but I do not know the
first thing about how to get to
those pins through EPICS.
Any advice or direction would be much appreciated. I am relatively new to EPICS development but am
experienced with with maintenance of EPICS
records and the like.
Regards
Peter
