@evvaldis, when I connect using the st-link is is saying no target. I switched the middle ports for the cable around and connected through the i2c. Is there any quick walk through you can give me?

i have this MPU http://www.ebay.de/itm/MPU6050-Senso...item43bc3560c4

just tried my board but it is behaving strange, just moving arround and after some time it stops and the LED starts blinking. so i2c error?
i can measure any pullups on sda and scl, could that be the reason?
the fetdrivers also get warm. how can that happen? 330ohm resistor should limit the current.

Hi all..
STM has very bad I2C. Me and my friend are working on software I2C implementation.
I hope new FW will be available within next week. Thank you for your patience.

Is this order of operations correct:

Populate pcb - connect 11.1 battery power - led light on? - connect stlink or other via swd and transfer over kws file- then upload gui via swd - remove battery and connect motor and mpu - connect battery
