Dear all,
I’m a complete newbie in this community. As a postdoc, I’m responsible of building a off-computer control system. I decided to use BeagleBone as the central controller. But since I have other academic jobs, I wish I could finish the project quick and dirty. So maybe I need some specific guidance on it.
Now for the first version of the system, my idea is just have two buttons appearing the touch screen and when I press either of the buttons, the BBB will send out a string through the serial port. I have another device waiting for the string command to trigger some control, so the rest is already ready.
I think this is rather easy, isn’t it? But I spent about a whole day today trying to figure out how to send the string out, and still cannot be successful. Not to mention the touchscreen part. I have experience in Matlab and LabVIEW programming, a little C experience, no Javascript or Python, and now I have a BBB, a 7-inch touch screen, a USB cable, and a 5V 3A power supply. I can make the serial port with connectors to the board with no difficulty. I have tried to boot the board with the 5 power supply and the LCD screen hooked up, and I could see the operating system. So could anyone tell me how to step into this field with a relatively quicker method? Thanks!
Sincerely,
Henry
