"Yes, that is right. You only need the mkblctrl_x file (depends on your frame configuration x or cross) .
The original BLCtrl ESCs does not have any Pullup Resistors on the Board. The Pullup is on the Mikrokopter FlightControl. In my case (Quadro X…"
"Hi,you should use 3.2 beta to use them.What kind of Frame are you using (X or Cross) ?How are the ESC's addressed ?Did they match the black numbering order or the red numbering order : http://pixhawk.org/_media/dev/apps/layout.png ?What LED(s) lit…"
at first you should to the basic setup of your Pixhawk.
Frame, Radio Calibration and Sensor calibration.
Then turn the Pixhawk off, eject the microsd card, and put it in the cardreader and stick it into your computer. Go to the card,…"
you are right. If one device on the bus blocks it, the whole system comes down. But luckily i had never this situation. All my past MK's and my current Pixhawk's are rock solid with these ESCs.
But for building a new copter, i don't…"
the. i2c bus is a multi device bus. You can connect multiple devices to the bus. There is a i2c splitter with a 4pin cable in your pixhawk box. This can be used to connect multiple devices to the bus.
In my case i have the GPS/Compass…"
it is only output mode, instead of pwm esc's.
The i2c is open drain, and already pulled high to 3.3v by the pixhawk. There is no need to have a level-shifter with the BL-Ctrls. You can connect them directly to the Pixhawk/PX4.
Mikrokopter UAV are very common in Germany. They use their own Brushless ESCs, controlled with i2c by their own Flightcontrol. From now on, it is easy possible, to convert a Mikrokopter UAV into a fully featured ArduCopter with a Pixhawk or PX4…
"In the video i have used a BlinkM MinM with a small EPP Cube (RG15) as a diffusor glued on it. The BlinkM and the MaxM did work too.
If you need a bright solution, you should use the MaxM if you can place it (size)."
