Hi all,
Having just purchased a cybermaster, I was reading around the net a bit
about it. One thing that struck me was the apparently quite limited
amount of memory available for user programs on the cybermaster.
Something on the order of 412 bytes.
This seems quite little. What do you guys/gals think? Has anyone run
into this limit yet?
Of course, both this limit and the firmware-imposed limits, such as no
stack and only 32 variables, could be circumvented by remote-driving the
cybermaster unit from the pc. Run a little task on the cybermaster that
informs the pc of any changes in inputs, and accepts commands from the
pc as to outputs. Then you could run any kind of program on your pc that
would communicate with the cybermaster over the serial port and control
its behaviour. Has that been done before? Would/does it work? Is the
radio connection fast enough for this?
Regards,
Johannes.

I always managed to run into it in my first projects. :-( Since I decided to transfer the real "intelligence" of the bot to the PC, leaving only basic intelligence in the mobile unit, the problems finished... but not only after some struggle.
