AVR-Chat

Hi all,

I am trying to find the best way to work around a few problems.

I am using the New Japan Radio NJW1157B in a project, it is a no
brainier volume / matrix/ EQ chip.

I want to build more modular code, so to this end I am looking at
writing a device driver (Library) for this chip, so I can say things
like Master_Volume(1); etc and it would bump the master volume by 1 Smile

As this chip works in 16 bit words on SPI, The first byte is a constant
for each instruction, I would like to use in my subroutines the
assembler equivalent of Master_Volume (low) and (high), with the high
byte containing the actual volume for the master Smile

Some of these pairs the second pair is more of a 4bit variable and a few
bits. Can I access these parts as Master_Volume,8 etc ?

Can I assign a new name like Master_Volume.8 = BSW ?

What is the best way to describe this so I can just shunt it out the SPI
port, also can I send an int to the SPI port and have CVAVR break it
into 2 8 bit values, to send and receive back my 2 8 bit variables ?
