interface I2C to PC to read output

[kcthomas]

i have an IC that has both an I2C and a SMBus output (16 bits). I would like to interface it to a PC to read and analyze the data. what is the best way to do this?

 

[Mark R]

Connect it to an microcontroller that has I2C and serial-ports and have the controller run translation software to transfer messages across the interface.

You can buy these ready programmed - check out the BL233

what about this

what kind of software/drivers would i have to use/write in order interface? all i need is the digital bits

If you have the I/O available, just feed the TTL into a parallel port on the PC and read the bits directly & translate them as necessary in the PC software.

If you're a bit shy on I/O from the MCU, then drop in a mux chip.

There are some I2C interfaces for PCs as well. Check out Circuit Cellar ( http://www.circuitcellar.com ).

Good Luck
