Hello all, I've been using ML to communicate with meters and motors through serial ports. The goal is to take serial data from a meter into ML, perform some operations on it, and shoot a command out to a motor drive. The issue that comes into play is getting the serial data in. fscanf() works just fine, but if the meter isn't sending data at the same rate that I'm polling the buffer then I either get old data or a timeout.
Is it possible to set up a real-time scan such that as soon as data comes in it passes it through (like a callback) and otherwise it just waits? It would be especially great if the software could run normally while scanning as well, rather than just not having a timeout and still stalling out the rest of the software.
I'll keep looking, but I hope someone has an idea!
