This is more complicated than the Artificial Intelligence Module I did at University few years ago.....:ermm:

@ Craig - No issue, Im just finding it frustrating that I cant grasp this.

@ Gail - I was waiting for a MCM 😉

Ok, so offset = 00000000 as you stated.

Then Bits 1-3 of byte 0 is what? 3,0,0 or 0,0,0 ?

It will probably help if I knew what you mean by 0x30? Is it related to 30000800?

(might sound stupid to you - sorry)
