Well, I finally got some time to get back to my SX Robotics today. When last I communicated I had setup the SX48 Protoboard with headers and was awaiting the breadboard in a Parallax order and some 8 MHz resonators from Mouser.

Here's what I have on the SX48 Protoboard 

(1) a single row of 16 female headers soldered into RC/RB along the bottom edge of the board

(2) a single row of 18 female headers soldered RD/RE/RTCC/MCLR

(3) a single row of 8 female headers soldered into RA

(4) a single row of 7 male headers soldered to the 4 Vss pins of the Servo connector and the 3 pin Vin/Vdd select for the servo power

(5) a double row of four male headers for the Power and signal lines of the servo

(6) a single row of 4 female headers for the servo data access

(7) a double row of 5 female headers for Vdd and Vss

(8) a small Parallax breadboard we are used to seeing on most of the demo boards, BUT, I had to take a chop saw and remove two rows of holes (the servo connections intrude into where it would otherwise fit unmodified, even if I moved the female headers out one more row I would still lose at least one row of the breadboard) Rotating it the way it would fit unmodified presents pins in a way awkward to wire up for sensors.


I have uploaded two photos, DSCN7599.jpg shows the board mounted on a robot chassis and you can see the whole setup. DSCN7600.jpg is a closuep of the area described in (4) through (7) above.


I also cranked up Jon's program SXBOT.SXB and got it running, I have no IR stuff running yet, thats my next project. But I did get his code running as is, then proceeded to create some subroutines for motion, GoForwardFast, AboutTurn, LeftTurn, etc. The routines make fixed behaviour a snap, its more like script writing than programming. I have uploaded that code, as BBRSXBot.SXB, 

Jon, and Gunter, great work ... everyone else, enjoy. I will post my results when I get the IR avoidance and some line following stuff going.
