I know this question maybe outside the realm of this forum, but I couldn't think of anyplace else to ask. This is more of a PC/Microcontroller question.
My new motherboard has an SMBus interface on it which is essentially i2C. You can connect i2C/SMBus compatible sensors and they can be read by a program like Mother Board Manager.
It should be easy to use this I2c bus to communicate with a microcontroller. I was thinking of passing information to the computer, or passing computer status information to the uC to display on an LCD.
Unfortunately how to access the SMBus from a programming language like Visual Basic is just about impossible to find. It may also be that I'm a complete noob to Windows programming as well. There's a device driver already installed for it, but how do I access the device driver?
Anyone know what it would take to access the SMBus on the PC side?
