Lately I had been using a color sensor to read some colors in terms of RGB and XYZ values. The sensor is supplied with a GUI on which I could view the results. The sensor consists of a chip with a microcontroller (i dont know which one) and connects to my PC via a USB. Now I want to access some values from microcontrollers memory to c++ so I could process the values using my own functions. The company has given me 'dll' file for USB and 'header' file for some reasons. In the pathetically written tutorial are some predefined functions that I could use to access the values.
The problem is that I have no experience of how to handle hardware like this using c++ and was wondering if one could give me a hint for how to start using the things I have above.
