Hi Mark, David, etc.:

Those modules seem amazing. Do you know any analog I/O modules accept external trigger, i.e. it has an TTL trigger input?

Thanks,

Yong

Hi David,

The high level EPICS software already exists in this file, which works on both Linux and Windows.

https://github.com/epics-modules/measComp/blob/master/measCompApp/src/drvMultiFunction.cpp

The low-level Linux driver for the USB-1608G-2A0, written by Warren Jasper, also already exists:

https://github.com/wjasper/Linux_Drivers/blob/master/USB/mcc-libusb/usb-1608G.c

All that needs to be done is to write the “glue layer”, which is the derived class mcBoard_USB-1608G.cpp, in this directory:

https://github.com/epics-modules/measComp/tree/master/measCompApp/cbw_linuxSrc

There are lots of examples, including the mcBoard_E-1608.cpp that can be used as a starting point.

Anyone implemented support for these device under Linux? measComp module looked real promising until read that only certain modules are supported under Linux, and this one is not one of them.
