I2C Esc?

Posted by Shawn on March 10, 2011 at 10:46am

Hello, I have been reading that I2c esc's can give much better stability (especially in winds, etc.) to our machines and wondered if:

A) The upcoming code release was going to allow to use these

or

B) Do you have a list of the fastest "standard" esc's

Thanks

    Being the I2C has a high impedance it will be neat to see how some conquer adjacent interferences.

    I do like is the idea to have less latency with needed control response with a very small light copter.

    I really would like to see I2C working with arducopter.

    I am under the impression that the Arducopter team are working on I2C ESCs. So it will probably be in a later version of the Arducopter kits. I2C bus can have difficulties though with noise and locking up so it certainly isn't perfect and certainly needs the dedicated research the team are putting in.

     

    As for fastest a reading of the code will show that regardless of the ESCs ability it will only change when called. Attitude control is modified at 10Hz in the APM code (less important to be fast).
