FYI - We have both shared code on this board and Duma's board that are not standard in TOS. I have put references to them in the iBox for this board. You will find some of the code he is using there. He is also using TTM_LRC which you can customize in length to your chart and is standard in TOS. There is a lot going on in Spd's charts. I would recommend starting there to build them.
