 01 Dec 2009, Stefan Ritt, Info, Redesign of status page links 
|
The custom and alias links in the standard midas status page were shown as HTML
links so far. If there are many links with names having spaces in their names,
it's a bit hard to distinguish between them. Therefore, they are packed now into

04 Dec 2009, Stefan Ritt, Info, Redesign of status page columns
|
Since the column on the main midas status page with fraction of analyzed events is
barely used, I decided to drop it. Anyhow it does not make sense for all slow
control events. If this feature is required in some experiment, I propose to move it

04 Dec 2009, Stefan Ritt, Info, Custom page showing ROOT analyzer output
|
Many midas experiments work with ROOT based analyzers today. One problem there is that the graphical output of the root analyzer can only be seen through
the X server and not through the web. At the MEG experiment, we solved this problem in an elegant way: The ROOT analyzer runs in the background, using
a "virtual" X server called Xvfb. It plots its output (several panels) normally using this X server, then saves this panels every ten seconds into GIF |

04 Dec 2009, Stefan Ritt, Info, New '/Experiment/Menu buttons'
|
The mhttpd program shows some standard buttons in the top row for
starting/stopping runs, accessing the ODB, Alarms, etc. Since not all experiments
make use of all buttons, they have been customized. By default mhttpd creates

A new page has been implemented in mhttpd. This allows web access to all devices from an [URL=http://midas.psi.ch/mscb]MSCB system[/URL] and their variables:

09 Feb 2010, Stefan Ritt, Forum, custom page - flashing filled area
|
One possibility is to use small GIF images for each valve, which have several frames (called 'animated GIF'). Depending on the state you can use a static
GIF or the flashing GIF. An alternate approach is to use a static background image, and display a valve with different color on top of the background in
regular intervals using JavaScript. I tried that with the attached page. Just create a custom page
/Custom/Valve = valve.html
and put all three attachments |

Just some idea:
The ultimate solution to that would be to do that completely JavaScript driven. You load ONCE the list of all

15 Dec 2010, Stefan Ritt, Info, New source file structure of MSCB tree
|
A long planned modification of the source file structure of the MSCB subsystem has been implemented. This is however only for those people who do actively
participate in micro controller programming with MSCB. The idea behind this is tha the central include file [B]mscbemb.h[/B] had a section for each new
project. So whenever a new project was added, this file had to be modified which is clumsy and hard to maintain. Therefore I took the project specific |
