Hi, i have to develop a configuration control for a microcontroller. For this i developd GUI using VC++ and µc controller programs are written in Keil. I have to send data from GUI to µc programs which are written in keil, where both programs are running on same pc.But i am not able to make communication between VC and µc, and i got an idea that can i write keil programs in VC, then i did that but vc is not supportng data types of keil, is it possible to write c51 in vc compiler? Thanking you
