Great FAQ!!!
Some suggestions:
x27.html :
You might add that any and all BCD variables must be dealt with straight
assembly, but then tell them how easy it is.
I just added something in the "I will still need to use some assembly
language somewhere, won't I?" section about BCD. I didn't have any
examples of using assembly language to access special machine features,
as one might do on any processor. BCD handling is a good one. I included
some example code - a normal routine for binary->BCD conversion, and a
little inlined one for adding. The conversion routine is pasted in from
my own software. The addition routine is unchecked!
x81.html:
You need to replace "do" with "to" in the title.
Done.
Great work (and thanks for the pwm example).
We should really build a library of source code like this, as the wheel
keeps getting reinvented far too often.
I've seen a few nice examples of something in this area recently.
Someone showed me a routine for setting an FLL to any frequency. You
wouldn't really use this routine in a real embedded program, as its
generality makes it too big. However, reading through it is the best way
I have found to figure out what to put in the registers to achieve the
specific FLL frequencies I actually want.
