Experimental Physics and Industrial Control System
Hi All,
I have one question and one bug (? ) report
1. Question: in IOC Application Deveoper's Guide (Rel 3.13.0.beta4)
wrote about I/O Event Scanning, but on dbScan.c (useing SCAN_IO_EVENT)
faild.
The reason is: piosl is initialized as NULL, and never updated. Where
is my failure ?
2. Useing waveform record with a very slow hardware, I used double
buffering and cahngeing the buffer pointer when the data is ready.
On medm display I have seen only every second buffer. In an other
situation (also with the modified bptr) the old medm display displays
wrong data but if I restart or starting a new, the correct data is
comeing. useing buffer copy instaed of bptr changeing helps, but
it costs memory and cpu time...
any idea ?
