AVR-Chat

I have walked through it, both manually and in the simulator, and it 
isn't loading any data.

   As for formatting data, there is extraneous data in the .eeg file 
that *I* didn't place there.  Here is the .eep file data:

:1000000000000000000000000000000102020303E5
:100010000405060608090A0B0D0E10121416181A0C
:100020001D1F2224272C3034373B3E42464A4E5275
:10003000565A5E63676C7075797E82878C9095994D
:100040009EA3A7ACB0B4B9BDC1C5C9CDD1D4D8DBCE
:10005000DFE2E5E8EAEDEFF2585AF7F9FAFCFDFEC7
:03006000FFFFFFA0
:00000001FF


and here is the code which is generating it...obviously there are values 
in here that *I* didn't place here.

;    this table provides the data for the intensity curve needed for
;    xxxxxxxxxxxxxxx.  the data represent the value sin^3 * 255 for
;    each angle from 0 through 90  at .9 degree increments
