Neil,

I was able to interface my assembly language program to the C program, but I would prefer to interface the assembly language program using a known value in memory such as Delay_time. I will try this using your example Blink(Delay_time). The manual is kind of vague on this subject. I learn by playing with example code and trying to understand what it does. There are many times when I need to use assembly because of timing constraints, but at the same time I would also like the power of a higher level language such as C.
