Dear William, I think we still need some experts like you to guide us on to be on the right track. Because the deeper we go in, the more difficulties we are likely to encounter. And sometimes we have to step back, and start from the fundamentals. Because the coding is not that easily picked up from sideways.
For example, now I'm facing two difficulties: 1) I need my BBB to communicate with a device that has a Serial-USB chip, which means that the only physical connector is USB. Is it possible to use a USB cable to connect the BBB to that device and use serial command to communicate? Does BBB need to install any drivers to recognize this serial-USB chip? 2) When coding the GUI program, I need multi thread functions. For example, some of the buttons doesn't work when I press one of the buttons ---- becasue the sub function when the button is pressed is being called, and the whole program is waiting for it to finish. But I need to have at least an emergency stop button. I don't know what is the easiest way of doing so. Please, if you would, share some of your ideas. Anything would be appreciated. Thanks!
