Hello all,
I will have a serially connected titrator (USB connected, not automatic) comprised of a burette, mixer and a potentiometer.
I have been given a set of commands (ASCII format, eg. B for filling the burrete, K for starting the mixer...), and I don't really know where to start with the program, hence why nothing is attached.
LabView will be used to control the instrument (filling the burette, controlling the titration and reading the voltage).
My question is, how do I properly communicate with the device? It has no own drivers, I cannot set up any DAQ since I don't have the device with me. I have the base parameters (9600Bd, 8bits, no parity, 1 stop bit) but that is it.
I usually start with the VISA serial, and then I get stuck in the case structure and the VISA writing.
Should I set up more case structures (one for the titration/dosing, the other for the potentiometer)? Do I use the string constants for the commands and leave them in the ASCII? The user of the program won't write any of the commands themselves, the interface is going to be the table E/V with the appropriate buttons (dosage of the solution, mixer control and then the calculations but no assistance required with those)
I have checked out some of the examples LabView provides, but it didn't really help me further (mainly the serial communications)
