writing examples in asm
-----------------------

These sources provide some useful for routines for use in asm projects
with goldroad ARM assembler.

Specifically, there are three useful functions...there usage
should be pretty obvious from the source

dmaMemCpy
---------     
is a memcpy() style function for transporting data with DMA


draw_string  
-----------
is a simple writing function to print a string to the screen
you provide a pointer to the string in r0, and the screen coordinates in r1,r2
the strings must be terminated will a $FF byte.

draw_string2  
------------
is a slightly more advanced function which can display the value of a memory
variable, whos address you supply in r3 when the function is called.
the format string should use a C(ish) format string,

e.g. " value appears here: %b " %b means byte, %w means word, %d means long word
