writing a C++ code for reading data from uC using USB

I am doing the project to make a microcontroller communicate with PC.
I am facing the problem writing the C++ code for command button to ask uC to display the data in my label.
How to write the code for C++ to get the data from the microcontroller?

i'm using a C8051F320-dk which already have a USB connector and a RTC.

my data will be the date, and time provided from the RTC. please help.

thanks in advance Posted in: #Coffee Room
