I2C ESC support, is it still planned feature? Reusing MK frame

Posted by kolin on October 3, 2011 at 2:45pm

Hi

I also have Mikrokopter quad with old FC1.2 (upgraded to 1.3) and Bl-Ctrl 1. 

I want to try put APM on it. If there will be support for I2c ESCs it would be plug'n'play replacement.

I read somwhere i2c support is planned, but when it will be ready for use? Would it be simple enough to do quick and dirty hack? Will planned support include Mikrokopter's ESC as well?

Thanks

    I looked at the code ant I think it should be enough to replace content of APM_RC_Class::OutputCh. First scale values to fit MK 1byte (if I'm correct, yet to be find out). Second use Wire function to send values out. I2C bus for ESC to be connected to I2C port shared with magnetometer? Can you confirm this aproach? Thanks

    Today I will try to spin up MK ESC with buspirate to findout how it comunicates.

    And please Tom, place your questions here, not PM. Let the knowledge avaialbe for all

    try it yourself, it's not that hard

    If you need some info about how to control I2C ESC with an ardupilot, ask me ;)
