MPU9250 Engin on #302

Open metehanemlik opened 6 years ago

I am designing and codding a mini-drone which is more likely crazyflie. However, mag calibration is a big problem when drone engine on. I am eliminating the motor effect to mag sensor by using some integers. But, these values always changing.

how can solve this problem please help

than you

We use the EM7180 for our flight controllers using brushed motors on our 35 g UAVs and don't have any problem getting accurate heading, etc.

ı my design motors are too close to main board

Closer than this: https://github.com/simondlevy/Hackflight/wiki/L.10-Maiden-flight

In any case, with the EM7180 it doesn't matter how close.

We have this https://www.tindie.com/products/onehorse/superfly-hackable-esp8266-flight-controller/ FC board that also uses the EM7180 but has the ESP8266 as host.

These work fine on very small UAV with brushed motors.

ı guess there is a real-time teaching system to converge to the correct heading estimate. It is a great work. But, ı cannot use this system. I am already working on my drone system which includes (the heart of drone)esp8266 + mpu9250 over one year. My drone stability and communication are okay but ı couldn't solve the motor calibration problem. I am planning to do swarm drone application.

Can you help me with the algorithm?

I am using Arduino ide.

Of course we know how to manage this problem, but you will have to pay us for our help. If interested please send me an e-mail at tleracorp@gmail.com.
