I want to make a program that can read the data sent through the serial port of Arduino. Is it possible to implement this function in Visual C++?
I have just tried the regular ways that VC++ reads data from COM4. However, I encountered quite a lot of errors and finally got meaningless data. And I cannot find any documents covering this topic.
Yes, it is possible. If you could post some actual information, rather 'quite a lot of errors' and 'meaningless data', we might be able to help.
If you haven't already done so (and if not, why not?), read this: http://arduino.cc/forum/index.php/topic,97455.0.html
