Hello, I am developing EPICS driver for reading and writing port. It is working fine with SCAN is not set to I/O Intr. If i set SCAN to .1 second.... 1 second etc.. I is working fine. But if i set SCAN = I/O Intr and monitor with >>camonitor PORT_READ it gives out put PORT_READ <undefined> 0 UDF INVALID and even is changing port value doesn't read value. The .db file content of longin record is as below record (longin,"PORT_READ") { field(DESC, "New Variable") field(DTYP, "asynInt32") field(INP, "@asyn($(PORT),0) read") field(SCAN, "I/O Intr") } I would like to know how to configure interrupt as it is working perfect with if SCAN sets to different value then I/O Intr. Here "read" i am using as asyn reason in driver for reading. Thanks Vishnu Catch India as it happens with the Rediff News App. To download it for FREE, click here
