Using 3 picaxe chips together

Hi there,

I am thinking to have 3 picaxe chips on my robot, one being a 28x2 which will have all the sensors attached and will hold the main programme, and the other two being a smaller variety picaxe chip.

The purpose is so i can have 3 different events happening at the same time (Light, Movement and sound)
im thinking ...
LED -on a small chip
Motors -on a Small Chip
Sound -on the 28x2 (because i think the different sound commands will take the bigger memory capacity).

I am mulling over ways for the best ways for the chips to trigger events to (talk to) each other.  I have a bad habit of over engineering things like this so thought it best to ask you guys, who are in the know.
My first thought was to put an LDR on the Analogue inputs of the smaller chips and a led on a pwmout of the main chip and use the brightness to give different values to the inputs of the smaller chips and therefore triggering different events.  Then i thought  i could do the same sort of coded trigger type thing using 3 or 4 digital inputs. eg...input 1 =1, 2=0, 3=1 (101). If trigger code =101 goto flash programme.

Any of you guys done something similar or have a better suggestion?

Send serial data. Serout and serin.

nice one…something else

nice one…something else for me to read up on and get my head around.

i looked at the link telefox gave me (cheers) but i think i need to start a little more simplified then that.
i’ll take a look at the picaxe website, but if you have any useful links you can recommend much appreciated.

Thanks
