[Jeff Ridgway]

Hello RTLinux community, I am new to RTLinux and am considering using it for a fast, medium-high volume data acquisition and control project. I have used QNX before for a fairly slow A/D and serial data acquisition (maximum sample rate 4Hz). Now I'm working in the "big leagues" on a project which needs a multi-tasking operating system which will digitize and process data coming in at a rate of 50 kHz (20 micro-second samples), from as many as 19 channels. RTLinux is a bone fide competitor to QNX because of its open-source philosophy. However I know virtually nothing about how I go about digitizing and processing data with it, including writing data acquisition drivers and processing code. I've also had Tcl/Tk recommended as a GUI and scripting tool. I have the Mandrake Linux version installed on my PC and am ready to write a prototype GUI and data acquisition system, in order to demonstrate feasibility and calculate operating speeds etc.. Any detailed advice which someone can give me to get me started in the right direction will be very appreciated. Thanks, Jeff Ridgway _________________ Jeffrey Ridgway, PhD Information Systems Laboratories 7047 Carroll Road San Diego, CA  92121 858.535.9680 [EMAIL PROTECTED] http://www.islinc.com
