Finaly those missing parts arrived. chips / boards are now in place (wow they are small :D )
And project can continue. Making code "complete" shouldn't take long now.
Little check (yep i2c bus work fine even between controller and powerbar has about 1m wire. (little offtopic :D I re-check and soldered all connections again when i2c scanner don't find anything at begin :D Then i start to think that, it should find atleast eeprom. And then i see it Wire1. All this time i thought robotank uses sda/scl and not sda1/scl1. But yeah i figured out eventually) :D
