I am using basic visa read and write example to control my temperature controller actually it works perfect but I want something else. First, I am reading temperature value continuously and it can be read on read string section but I want to but numeric indicator to see the temperature value is that possible? And what function I have to use for it? Actually I used scan from string to do it but I have not checked yet it is working or not?
Second, I have to set temperature sometimes on the controller actually I can do it writing tset=025.0 to set temperature 25 F, it is working when I write this command to panel(string to write), but I want to make like numeric controller or something like that instead of writing command for every setting is that possible. I want to increase or decrease temperature by pushing increase or decrease button instead of writing tset=0.250/r. Could you help me about that?
Third, I want to run some parts of program continuously some part when I want to run, is that possible, now I did while loop and my example working continuously. I want that because when I set temperature that does not have to run continuously because this is one time command to read temperature value this section run continuously because temperature on the experimental set up is changing an I have to see this changing, for example I set temperature 100 F and than controller heat up device 100 F but this command is one time command, but reading temperature command should work continuously because temperature is changing and I need to read temperature for each 60 sec and I can do that part.
