Need advice on ProAtom 24 seiral communication
« on: July 09, 2007, 12:46:16 PM »
I am looking to use the BasicAtom Pro24 as a sub system for a more advanced robot, its basic job will to be taking in input from 4-6 sensors and making motors adjusting of some sort.  The other thing I was looking at for this, is communication to the main CPU.  I was planning to do this via Serial, but there are problems:

1.  The basic stamp has to sit and wait for a communication.

2.  While waiting, it does nothing else.  This would result in robotic failure :(

So I was browsing other basic options. and saw the basic atom pro 24m..

it claims to have a buffered serial communication system.. 

which would basically allow it to recieve serial data while not listening, correct?

Could someone explain what it means by buffered?

robotboy, most microcontrollers with hardware serial communications (like pic, avr, and stamps) have a buffer that recieves a character and holds it on memory while you decide what to do with it.

I don't know with basic stamps, but with "normal" microcontrollers, there are interrupts that trigger when a serial commmunication is detected and also they have special registers for that, so in your code you ask "Is there data in the buffer?" and it will return either a 0 or 1.

Look in the PBASIC reference if there is an interruption for serial communications or at least a command that will let you check if there is data available.

Thats what I had thought, but I read about the basic stamps that they had nothing like that, so I was unsure. 

Appreciate the response,

Cheers

Just send your serial data continuously so the robot wont have to wait?

Or have your robot use the last serial command until it recieves a new one.
