Hi Gary,
Thanks for considering my humble controller design for your system.
I'm a little confused on what is working and what is not. Are you getting serial data out of the computer but not recognized by the STAMP? If so, one of the quirks I found with the STAMP processors is that they're not terribly fast, and the serial communication needs to have 2 stop bits in order to have the character strings be recognized reliably. I am driving mine from my Linux system with Predict, but I modified it to force the extra stop bit when opening the serial port. (I also modified it to create the properly formatted az/el string too.) I've just got it spitting out the position every second, and the controller looks for the position to change by more than a click (6 degrees az) before taking action.
So, if the serial port settings can be tweaked, is there a place to set the number of stop bits?
Hope this helps,
Greg KO6TH

I am trying to put together a computer controlled az-el rotator system with BS2 processor control like KO6TH using U-100 rotors. With Orbitron for satellite prediction and Wispdde comunication I do not get data display on the LCD display. The display works for other program titles. I tried Nova (demo) thinking the BS2 needed different input but still nothing to display. I used Free Serial Port Monitor and could see ASCI output that looked like what I wanted with satellite name, AZ and EL with numbers but the values did not match the satellite tracking program, they never changed! This was true with both Orbitron and Nova. I am using Orbitron 3.71, Wispdde 4.2, 4.3.0.7 and 4.3.0.2 modified by AD5JN. I have tried all the Wispdde programs at 1200 and 9600 baud. My radio is a FT726 so there is no CAT control there to confirm operation of other equipment. I have tried BS2 programs off the web from KO6TH and SAEBRTrack with out success. My BS2 is rev G and I am using a SC-IOREL4 relay board to mount the BS2. Demo display and relay programs run fine. I do not understand why the data into the BS2 isn't the same showing on Wisp panel. Any thoughts? Gary AB3ID Snow Hill, MD
