  1. Dear All, I'm new to this forum and I'm really glad I became a member. I am currently in the phase of designing a simple program which can control all the DAQmx channels using a configuration file (.ini) which is capable of change voltage range during mid-simulation. At the moment my .ini file reads as follows: [AO Channel 1] Name = T2 Physical Channel = cDAQ1Mod1/ao0 Max Value = 10 Min Value = 0 [AO Channel 2] Name = T3 Physical Channel = cDAQ1Mod1/ao1 Max Value = 10 Min Value = 0 [AO Channel 1] Name = T2 Physical Channel = cDAQ1Mod1/ao0 Max Value = 5 Min Value = 0 [AO Channel 2] Name = T3 Physical Channel = cDAQ1Mod1/ao1 Max Value = 10 Min Value = 0 My LabVIEW VI for the .ini script is attached. I'm relatively new to using configuration file functions and I don't really understand where "Get Key Names" section should be wired to. I have placed a constant on it for now which reads the "AO Channel 1" but how can I get it to read all the channels in the .ini file. I am welcome to all suggestions here, I just want to make sure that I don't cause any problems to any of the channels and use best practice methods. All constructive criticism welcome! Thank you. Read Configuration (INI) File (1).vi
  2. What is the standard, or is there one, for storing configuration data that will be used to initialize I/O channels and GUI "stuff"? Example Part 1: Executable needs to read from a file some UI initialization Info: [GUI] type = touchscreen size = 800x600 InstrumentName = GS342 Language = Englusskie Example part 2: We need to know what class of I/O to use for each channel: [GS342.CH1] ID = MicroFlex ComPort = Com1 PropotionalBand1 = .35 ProportionalBand2 = .67 [GS342.CH2] ID = USB-TCAI Node = 0 InPort = 0 OutPort1 = 0 OutPort2 = 0 Slope = 3894 Offset = 49920 [And on and on...] The "ID" tells me which class to use for that channel and the rest of the stuff has to go into that classes vi set somewhere. My question is: Is there a better way to do this? Remember, users need to be able to change these values and I want them to be readable for troubleshooting. Also, is it best to have a library of all possible values and read them into a typedef cluster or should I read them as an array of Name/Val pairs and then pull them out in the class vi that needs them? I cannot just white them into each class because they change (Proportional Bands need to be tweaked, etc...) I also would like to keep the property options somewhat standardized (ID, Max, Min, Pb, Com, etc...) so when I create new I/O classes I can just unbundle the options I need. Thanks, Jeremy
  3. Opening and closing config files as a binary file but using the config VI’s to sort and Perce them. I was told this can be done any one know how?
