Hello, I'm working on a project that requires me to perform communications between a Beaglebone Black and a pc running linux/unix/ubuntu.
We figured out how to communicate over the port manually via terminal commands (after exporting the port through c++) and now I'm trying to get some code written in c++ so that we can get away from bash commands.
#define deviceport "/dev/ttyACM0"
using namespace std;
int main(int argc, char * argv)
for(int i = 1; i <= argc; i++)
file << argv[i] << " ";
file << "\n";
Here's the code I have right now... My problem is that is sort of
works. By that, I mean after I compile and run this code, the beaglebone I have listening for data on that tty port doesn't get the output- until I
echo (somevalue) > /dev/ttyACM0
At which point it promptly sends the data over, and I see the output on the beaglebone as (whatIputin)(whatiechoin) of course there are no spaces or line breaks or anything... but that's not my concern. What I want to know is how I can forgo the echo nonsense, as we need fully automated transmission of information from PC to bone. I'm rather new to c++, so I don't know exactly what to call this problem, otherwise I'd likely have found it on google three hours ago... I would just like to know what I have to do to actually SEND the values, I was going to read the source of echo, however I'm running on a live key, and haven't set up my apt-repositories. I would just run bash from c++ but our project leader believes bash is too insecure.
sorry if my wording/spelling is a bit erratic, I'm frustrated, its 4am, and the laptop I'm using has an annoyingly sensitive touchpad that sends me halfway through a paragraph as i type when my palm brushes over it so that I unknowingly type half of a word in the middle of nowhere. Anyway, if you know how to solve this problem I would greatly appreciate the help. Also, if you do help, please provide an explanation, code I don't understand is as useful to me as the code I already have which is non-functional. If it helps, I have downloaded a library which provides functions for this sort of thing, as well as an example which I have tested and it DOESN'T have the problem my code does, the issue is that I cant tell the difference between what my code is doing and his.
google that, first result should go to the library.
