Re: NAZE32+latest baseflight frozes on PC and in the air

Confirmed with PWM receiver - PWM interrupt reshuffling introduced some race condition in I2C driver. Will debug and see what's up. Should not affect PPM receivers. For now, go back to some older build, something from early April should be OK. Thanks a lot for confirming the likely root cause. Debu...

The problem occurs with the hex file from the commit on 8 april and newer. With the commit of 6 april there is no issue everything works just fine. Did you try this? April 8 version locks up?

Re: NAZE32+latest baseflight frozes on PC and in the air

The good news is that the firmware from April 6th is ok. 2 batteries emptied. No issue.

Being more specific: https://github.com/multiwii/baseflight/tree/f336fc8d20e752d1b7f31b7fa01a66365df0b273/obj
is the version I use. Works on my quad.

Re: NAZE32+latest baseflight frozes on PC and in the air

Hi, It seems I am not alone... Short background story: I got a small quad (Warthox frame, 2208 motors, 8x4.5 props, 3S 2200mAh LiPo). Naze32 of course. Totally awesome flying. Very predictable behavior. Light, quiet, fast. The firmware was old. So old that I have to use the MultiWiiConf tool to conf...

Re: Tricopter and yaw if servo link is not perfect

Well, for those who are having the same problem: adjust the Yaw I parameter. In my case moving from 0.070 (default on Baseflight) to 0.090 and the tail no longer drifts.

In hindsight it's relatively obvious.

Hi, Maybe a basic question, but I cannot understand why this would be happening what happens: I got a tricopter. Fun to fly in general.

So where do I go from here to get my quad to stop drifting in acro? It's quite a lot of drift by the way, about a walking speed. Is it normal to expect to get some drift or should I be aiming for virtually none? There is no drift in acro mode. The only thing you can get wrong is that the quad chang...

Adjusting parameters in flight via receiver channel value?

While moving my Naze32 to a new quad frame (frame, motor, props are new), I quickly realized that the old parameters I used are way off.

Re: Not enought power to fly ?

Your battery is not strong enough. You have 4 ESC's of 30 Amps each (max) so you need to be able to draw 120A. Your battery can only deliver 66A (2,2Ah x 30 c). That is only half the power your engines would ask at full power. The motors draw max 20A, thus the worst case would be 80A, which is stil...

Re: Rough servo- Needs 5.25v droped to 4.3v

Get a diode which will drop (depending on the type) 0.7V.
However I think you are following a red herring here. I guess the voltage from the BEC has noise, while the USB is clean.

As stupid as it sounds, you have to get rid of the vibrations. There are only few possibilities: motors (remove props and prop adapter), prop and prop adapter. And the prop wash if you happen to have loose parts vibrating in the prop wash.
