interfacing mcs51 sht75

I just bought a expensive SHT75 from my country, but i am poor in 8051 assembly language and need some guide to write the code.

i can understand and write some simple code like running leds,displaying a LCD.But when come to this sensor, how to read the signal,send and display the reading in LCD. How to do it?

I had read the datasheet of SHT75,but not so clear about it.

Anybody can guide me please?With the code or some reading sources.

If you can deal with C-code here is one example:
Code:
This application note gives an example for microcontroller C code. It includes code for:
• Readout of Humidity (RH) or Temperature (T) from SHTxx with basic error handling
• Calculation of RH linearization and temperature compensation
• Access to status register
• Dewpoint calculation from RH and T
• UART handling (to send the final data away, e.g. to a PC)
