Using Atom for mixer only
« on: April 01, 2018, 07:35:27 pm »
I'm considering using an Atom CC3D as just a mixer. I need to take 3 inputs to control 2 outputs - where
out1 = (in1 * in2) + ((1-in1) * in3)
out2 - ((1-in1) * in2) + (in1 * in3)
where inputs are 0 - 1

Can i use a throttle input as in1, and say pitch and roll input as 2 and 3, and configure this in manual mode so the gyros don't affect the outputs?
Im assuming I need to scale this - so throttle needs to be 127 on out1, 127 on out2 mixer, then say 127 on pitch out1, -127 on pitch out2?
And -127 on roll out1, and 127 on roll out2?
These are driving servo outputs normally, but could be motor outputs. I assume that's just a setting on the output type.
These units are so inexpensive and powerful, seems like a useful way to get this function.

That sounds reasonable.

You may have to set "Disable Sanity Checks" in System -> Settings -> FlightModeSettings.  Press the red up arrow at the top of the page to save it permanently.

You may also need to set it to "Always Armed" in Configuration->Input -> ArmingSettings
