Hi All,I've done this with a couple of drivers already - it's not too hard.
I'm starting to convert our serial drivers: drvAscii, drvSerial, tnetDrv to EPICS R3.14.0beta2.
- replace the OS primitives with EPICS OSI calls, i.e. instead of vxworks semaphores use epicsEvent or epicsMutex; convert vxWorks tasks to epicsThreads() etc. - For VME, use the devLib calls to register addresses and IRQ handlers etc.
I also have a (I guess pretty portable) header for doing endian conversion and I/O calls which I could contribute.
Regards -- Till
Has anyone out there done this already? Does anyone have a recipe book for doing this?
In particular, what do I do with the VxWorks calls? Allan Honey and William Lupton used a "glue" layer to translate
VxWorks calls to solaris calls a while back with an alpha version.
Is this the recommended approach?
Thanks in advance.
