It's not the worst place to discuss the PropBOE...
I understand the Propeller Proto Boards can directly replace the BOE on the BOE Bot. (more or less).
Has anyone tried this? could be a simple way to start learning Spin, if you allready own the boebot.
I just could not wait for the PropBOE, so I went ahead and made my own versions in the mean time..
Still I do Look forward to a more "Professional" version from Parallax though...
Mine just don't loudly proclaim the Professional quality of the BOEBOT,
They just sort of whimper and moan about the tragic lack of craftsmanship I've given them...(sigh..)
Anyways, what was You wanting to discuss about the Prop Bot? anything in particular?
Or like me, You just want them to hurry things up some??
When the Propeller Spin Stamp came out, I made a Propeller BoeBot using that on my BOE along with an xBee AppMod. BoeBotBasic was originally developed on that setup. Sometime later, I revised my Propeller BoeBot using a Proto Board instead and included an xBee, SD card, HM55B compass, and a PING))) and its servo bracket. The version of BoeBotBasic in the Obex is for that Propeller BoeBot.
I put 1K resistors in the servo control leads and the IR detector and PING))) outputs. I modified the IR LED resistor values for the 3.3V output of the Prop. The compass is interfaced through an I2C I/O Expander to avoid dedicating any more I/O pins to it. I left the normal Proto Board accessory kit stuff in place, so the VGA / keyboard / mouse I/O works.
There are pictures and a bit more of a description in the old Projects forum here.
The PropBOE is a very good thing. When I first got a BasicStamp BOE, I found that one could easily overload it with tasks that would slow down its ability to move. Why so? One processor has to handle all and everything, so the PWM output often had to wait for something else to finish before it could send more output.
With the Propeller on board, you can keep the motors turning while sensors and navigation are handled independently. That is a huge advantage.
I still love the BasicStamp for bench testing senors and small tasks, but the Propeller is really a superior device for 'the complete robot'.
