ATmega168 flash size

[pomprocker]

So before I get in too deep, does anyone have any idea if the mega168 has enough room to hold code to control diff drive movement, pan and tilt servos, 2 small 3DOF arms, and a blackfin camera hooked up to its uart?

Is there a way to add external flash memory if not?

Would I need to increase the clock speed with an external crystal?

Have you considered upgrading the chip to something bigger? Maybe a atmega128 or atmega640 like Admin's axon uses?

Yeah I plan on getting the axon.

But for now I want to stretch the $50 robot to the limits!!

Not to put  a dent in Admin's sales, but I'd like to make more tutorials for the $50 robot upgrades.

Count up the possible number of io ports you would need and they may help answer if the 168 can handle it.

Yeap, it has enough memory and then some. My ERP originally used the ATmega168 before I invented the Axon.

The ATmega168 has 16kb of flash.

My last version of Axon software, with *all* header files and features included, is 16kb (see image). The new beta software is closer to 20kb. But again, thats with *everything* included - most you can just comment out.
