iBus - Eachine Racer 250 w/ Flysky i10 Transmitter #2

Closed jimparker closed 8 years ago

jimparker commented 8 years ago

I am currently using this transmitter and 10 channel receiver via PPM input. I have access to Aux 1-4 and standard flight control. I am debating setup via the recently added iBus support in Cleanflight. I have not yet figured out how to wire the receiver to the Eachine via a serial port. Also not sure if this would be advantageous to bother figuring out. Any thoughts would be appreciated.

On a side note I modified the Eachine Racer frame to allow 6045 bullnose props to fit. This turned out to not be a good idea. My Luminier 1800 35c batteries drained in about 4-5 minutes. Turns out the motors don't work well with that size props. Go figure ;). That said the sound level of the drone was really quiet and flight was very stable. I could hover at around 7-10% throttle. There was no punch out though. Starting to understand why people have multiple drones and different configurations suited much more for different things. The Eachine was/is my first non syma/hubsan drone of which I purchased them all. Rant complete.

I don't use serial rx, but the usual way is signal to rx-pin on flexiport and configure uart2 to use it. If your research doesn't help ask on rcgroups. ;)

Any benefit to using serial.

PS. - just ordered the falcon 250. Lost the Eachine in high wind and cannot find it. Any gps method to avoid this in the future.

it's digital transmission, should be better than ppm: https://quadmeup.com/pwm-ppm-and-serial-rx-explained/

I used this guide and everything works as expected: http://blog.marax.cz/2016/03/ibus-with-cc3d-and-cleanflightbetafligh.html

right now I've stock ESC and oneshot doesn't work, but I read somewhere that OneShot125 is exclusive to PPM (it don't work with PWM), is this true - if I flash my ESC with BLHeli will I be able to use OneShot with IBUS?

You will. Afaik this restriction only applies to openpilot.
