[Emc-users] Sampler, overflow + header in output
Sampler I found is simple to use then executing it from using a M1xx command, algorithm of shell script below: 1. Disable sampler. 2. Added an extra option to halcmd command read until buffer is "empty", used number of samples zero. Execute with this option to empty buffer. 3. Enable sampler 4. Run halsampler, there is parameter for selected channel and number of samples set then using "M100 Pchannel Qsamples". 5. Disable sampler. In 2. old values are flushed otherwise there may come old values first. Sample data is saved into a file with file ending .csv and it essentially is but with a space as separator, this work great. Think it is a good idea to add emptying of buffer but are a little bit in doubt about best solution? It might be sampling should be done until buffer is empty then sampler is disabled, maybe the best option is as I did? Or any better idea? Even though samples have been flushed there is a overflow message then samples is started, this is an annoyance and should be removed to produce correct message but did not yet figure out how. Shell command "halcmd show pin sampler.n.pin.* " show information about sampler pin(s). In particular type and information about net where it is connected. This printed information I plan to add an option so it will come before sampled values which is very useful then data is saved in a file, will also add either net information or pin as header for columns but are uncertain at this point which is best. Do anybody know if there is any not to hard method to access the information from "halcmd show pin sampler.n.pin.* " from within C code? Or maybe calling the halcmd command from C code is the best solution? Or maye I better look into the halcmd code myself. This extra option to automatically add information about which net the sampled values are connected, anybody else interested?
