[oopic] Re: OOPic-R limits?

I'm not sure an Oopic is best used for LOTS of servos. I have an
SSC32 I'm using in conjunction with two Oopic Rs in a 'Johnny 5' type
bot, with almost all the servos hooked to the SSC32, and I still run
up dangerously close to the 'magic 86'. I do have several (4+)
sensors etc. that the Oopics run too.
I swapped out the standard EEPROM for a 256k one so I can write some
humongous code (that being apparently the best way to utilize the
EEPROM). I'm not an 'efficient' coder, I'm sure there are better ways
to get the most out of the hardware, but I still bludgeon thru.
Since I have probably more hardware than would be necessary for a
more efficient programmer, I haven't needed to tweak the code to use
every last bit. Still, I've found that maxxing out the hardware seems
to produce (for me, at least) unpredictable results.
In general, I think going to about 85% of capacity is the best I can
expect. That also leaves some wiggle room for final tweaking.
Also sure one of the Oopic gurus here can give you a more precise
recommendation.
Twelve servos! Wow... that's around 60 bytes already. Good luck!
