looking for help. trying to display temperature on lcd - saad...@gmail.com - Jul 27 8:27:02 2009

hello,

i have to make a project for one of my courses in which i read temperature from a thermocouple and display it on an lcd. i am using an Axiom CME11E9-EVBU board and the lcd that came along with it. So far I have managed to write the program and I am getting the temperature readings and display them on my computer monitor. but I am unable to display this to the lcd. i have posted the code that i wrote so far below, if someone could have a look at it and guide me in the right direction?

thanks
