MultiWii

Hello. What pins used for SERIAL0 on board based on ATmega32U4 MicroWii ? I want to use OSD+Blutooth+USB at same moment, so I am going to use SERIAL1 for bluetooth and SERIAL0 for OSD. This board have special pins that associated with SERIAL1, but I could not find pins for SERIAL0. In config.h board...

Something that has been troubling me. The FAQ says first trim quad in acro mode just using the trim on transmitter. The trouble is that it's easy for my tx to go out of the range that let's me arm/disarm. Is it enough then to just trim my tx using the GUI to get the pitch and roll to 1500? The trou...

LPF does not take affect. BMA180 LPF filters placed in sensors.cpp Default value is control = control | (0x00 << 4); // that equal to 10Hz ( in future I'll use binary values because datasheet use binary) I try control = control | (B0011 << 4); //that equal to 75Hz It not take effect. And finally i t...

Thanks for attempt. I'll try LPF and tell results.

Just a second. On this board i have blue diode that start flash when changes applied.

This vibration level on 40% of power (after it copter whant run away from testing stand).
Thantks. I'll try low pass filters. But i am not shure that it may help. In LEVEL mode copter dont change drift direction.

What level of vibrations is critical? I have just +/-4 poins oscilation on acc, according to GUI.

then land and turn on ANGLE and see where copter want's to drift. Then land and trin ACC with sticks. Copter must be disarmed. Then throttle to max...and then move roll/pitch stick in desired postition. ACC was calibrated when copter stay in place in ACRO mode (it was very difficult, but I did it)....

So, first of all I should take quad in place in ACRO mode and only then make ACC calibration and use LEVEL mode Right?
But what is role of ACC trim? May i correct ACC level settings if it is not perfect?

Hi all. I have troubles with MultiWii 2.2 on my HK 328P board: I cant hold quadro (plus scheme) in place, it always move. PID settings looks like correct. In ACRO mode I may not have enough experience, but in LEVEL mode it does not want to stay in place too. ACC trim looks like fine. Initial state: ...
