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

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

the adress for the ESCs is 0x29+motor number (so 0x29, 0x30, 0x31 and 0x32 for a quad)

you need to send one byte (0-255) to each ESC

then you need (i think so, have not tried without that) to request data from each ESC (1 or 6 bytes, I'm not sure)

this data you get back has something to do with the current flowing through the ESC, you don't need to do anything with that

 

that's all

How far did you get on this, any progress ? I too am interested in getting a Hexacopter off the ground using this approach.

Unfortunately almost nowhere. I hope to have enough free time to look at it.
