Hi! So I've received the batteries and I was able to calibrate. It was not so easy. it's like the serial conection is not so clean and the connection failed. I had to unplug the ftdi and power supply many times. WriteInstincts.ino didn't work to calibrate by typing "c" so I did the calibration within Nybble.ino Now it's ok, calibration reacts, and I was able to set the offsets and save them. Now I'm trying to play with remote control but no reaction. But that's another story :-) I will check the steps after calibration in detail in the documentation.

@Boris Jülich ok thanks. It's quite similar yes. I'm waiting for the batteries then I will continue the tests and diagnostic.

I ordered the batteries, I will receive them next week. Of course I'll keep you informed.

OK great. I'll keep you informed as soon as I receive them. Thanks a lot!

Thanks for your quick answer. So, I will order some batteries. I didn't see any information about the capacity in the documentation. Are two lion 3.7V 800mAh enough?

Hi, I'm facing similar issue. I've loaded Writeinstinct.ino and answer "Y" to every question. Everything was successful but when I'm typing "c" Nybble is only beeping shortly, the serial monitor display the joints values but nothing happen on the Servos. They don't move to calibration mode. I've tried to set some offset but nothing move. I've checked the servos cables and they are correct. I did several try and servos moved after the Instinct update step. I didn't receive the battery yet but I've plugged an external power supply with 10Volts (I've tried different voltage from 7.4 to 12Volts) I've tried to load Nybble.ino, initialization seems to be ok but calibration mode has same behavior as before, servos don't move. And I've also get an overflow message. Any idea what's wrong there? Thanks in advance. Here an extract from Nybble.ino: * Starting * Initializing I2C Connecting MPU6050... Testing connections...
