GUI for smarthome project

[amico]

Hello all

i am building a smart home project using

a microchip pic16f877 and digital sensors with RS232 user interface,

thus, I want to create a gui using visual basic 2008

can someone please tell me how to connect

a command in the gui (lets say pressing a button to get temp measurement)

to a function in the PIC code

and getting back the information to the GUI.

Thanks,

amico

what RS 232 interface are you using ??

Normally a MAX 232 is used to interfaces a PIC and a PC, since the PIC operates on a 5 V level, the RS 232 needs bot +12 and -12 V levels, with the MAX 232 the interfacing becomes easy as +12 and -12 Volts are generated internally by the MAX.

What language are you using assembly or C? with C you can use the printf commands to send commands/data to the PC.
