help finishing temperature sensor using asm code, please and thank you

hi wondering if anyone can help me out with this, ive got the lcd displaying information, but i want it to display the temperature using the lm35 and adc0804 as well, using asm code. Basically i need to get the current reading from the lm35 and convert them in the adc0804 and then display that reading in degrees on the lcd display. I have found some similar projects like this but they were written in C. any help needed, thanks in advance
