Unfortunately...I completely agree with your rant.
Idiots are ruining a hobby that I respect and enjoy.
Nothing good happens when government has to get involved.

Has anyone done an autotune function for MW. I know about BradWii (with autotune) and the autotune port to cleanflight....Not what I want.... I like the concept of Brad Quik's autotune but it requires the use of BradWii which is a rewrite of MW. It would be good to have B Quik's autotune that runs o...

Hello, I have (or had) Crius MW SE 2.5 from BG. It was running MW 2.4. NP. The I2C communications to the on board sensors completely and abruptly failed! Somehow, this also destroyed the FTDI (strange!). The I2C errors cause the fast blinking LED (no sensors!). The FC still has some functionality. B...

David Just an additional note.... alt.EstAlt = (alt.EstAlt * 6 + BaroAlt * 2) >> 3; can be simplified to: alt.EstAlt = (alt.EstAlt * 3 + BaroAlt) >> 2; This yields correct calculation and identical damping effect and eliminates an un-neccessary runtime multiplication operation. (faster is always bet...

David The code should be reverted to: baroGroundTemperatureScale = ((int32_t)baroTemperature + 27315) * 29.271267f; ...and... alt.EstAlt = (alt.EstAlt * 6 + 2 * BaroAlt) >> 3; The reverted code corrects the calculation of 'baroGroundTemperatureScale' : this fixes a bug . It should be noted that the ...

I just found out what 'Hanlon's Razor' means....
hehe...
And...yes I agree.
Thanks for that....

Dennis

Thank you for answering the question....
It is what I thought...
Corrects a bug and also eliminates 1 runtime multiplication...

Dennis

So...
What was the reason for writing the code like that?
Why not include comments that explain this?
It is open source and other people will look at it.

I found this link that pertains to the IMU.cpp code: https://git.ece.iastate.edu/microcart/microcart/blob/570004ca5732a7d0a81adbd719c66d07b9d465c7/misc/Multiwii/MultiWii/IMU.cpp The following is an excerpt from the link: if(calibratingB > 0) { logBaroGroundPressureSum = log(baroPressureSum); baroGr...

All, Regarding deadband..... The idea of a deadband is to quiet "chatter" (noise) around a particular value (value = 0 for the IMU.cpp cases) and not affect other values outside of the deadband. Identical deadband functions can be cascaded (in series) and still produce the same output. e.g...

I have Crius MW SE 2.5 on TL250 quad frame running MW2.4 I have 2 items that I think need review in the IMU.cpp file. Item 1: The existing applyDeadband() macro affects the values that are outside of the deadband region. This affects the calibration/linearity of the system. This is not a standard de...

Hey All, Thanks for the this good idea. I have Tarot TL250 (quad) with Crius SE v2.5 & MW 2.4. I added an abbreviated version of this to my code for roll, pitch, level, altitude. I use PID_Controller 2 I have 5 chan tx so I used sticks to select which PID (used multiple profile selection code) a...

The analog transmitter and receiver from my CP heli has a range of about 400+ yards. I was quite disappointed when I used this setup on my quad (Crius SE V2.5 FC running MW 2.4) because I could only get reliable operation at about 200 feet or less! Bad! The problem was traced to occasional PPM glitc...

Hey carlonb,

Thanks for quick reply and explanation about the AH and the POV. I get it now. All is good.

Dennis

This doesn't make sense to me.... MW2.40 Conf Attitude.jpg The attitude display (upper right) indicates roll to left but roll indicator shows roll to right. The graph displays the acc, gyro, mag roll axis and indicates roll to right on all sensors. BTW: The Android EZ-GUI app has the same display ch...

Hi, I have a MW SE 2.5 on Tarot TL250 frame. Mag was having serious interference problems creating yaw instability (about 20+ degrees shift). I cut up a tin can (for a shield), placed it directly under FC (about 3 mm froom PCB) and connected it directly to battery minus. This eliminated my mag probl...
