Dear all,

at Bochum university, we have developed a CAN bus interfacefor the

Raspberry Pi computer [1]

using the SJA1000 stand-alone CAN controller.

We are using this interface to control the high voltage power supply modules
EHS 8 620p-F and EHS 8 210p-F from ISEG [2] via the crate controller ECH238.

I have programmed a device support for these high voltage modules based

on our Raspberry Pi Can interface.

You can find the sources for the device support as well as the schematic

of our CAN interface on github:

https://github.com/ffeldbauer/epics_RPi_can

I will upgrade this repository with a device support for our Wiener VME

crate, and some custom hardware.

The VME crate has an CAN interface which can be used to read out

voltages, currents, temperature and status of the crate.

Up to now the driver support in EPICS is only synchronous. Is there any

documentation on how to program an

asynchronous driver support? For some other devices we would need an

asynchronous support.

Best regards,
Florian
