Thermometer with PIC

Hi all.
I try to make a thermometer using pic16f690 and temp. sensor TC77, but i can`t write the code .I`m new in assembly programing and this is my first project. Have somebody any code about this or similar, or maybe some code how SPI mode actually work?

Here -> **broken link removed** you can find some SPI code examples in C.

That`s great. Thank you so much .
