Hi!

I'm computer science student but I have very little knowledge of electronics.

Its possible connect a two-wire device to LPC1769 board?

To be more specific I would like to connect parallax SHT11[1]
to LPC1769 board.
I know that LPC1769 supports UART , I2C and SPI device but I can't found something about two-wire bus.

Thanks for all.

Yes.

This protocol is no 'standard', so it's not direct supported. You have to write (or google) your own driver.

Yes, but where I connect fisically the device? in I2C ports? In SHT11 datashets says : "

Any GPIO pin you want. Reading and writing this pins is job of your driver, so you can use any pin you want.
