It's not a new thing that people can't get the pixhawk to work with emax escs.
If someone has any solution to this problem, please post it here.
If there are no solutions, then could it be possible to make a firmware change to allow stuff people have bought to work?
(Pixhawk won't calibrate the Emax escs on boot)
Did you have any luck on this?
Waiting for the solution? :(
Any solution after few months? because i can't do anything... I'm think that i will change my emax 4in1 by qbrain...
Do you say if remove these two resistors, then emax will be compatible with pixhawk?
Do you test it? do you have any video or something?
yes, remove those components, one is a capacitor and the other a resistor... after that, arming/working with pixhawk is doable.
I dont have a video, its really and easy fix.
It has been frustrating getting my quad to fly with the Pixhawk (from the APM) and now I have hit this Emax ESC problem as well.
I am thinking of
a) removing the (pullup/pulldown?) resistor & capacitor as suggested by Aldo Vargas
b) dead bug wiring a line driver 74HCT244 as suggested by squarepeg
but in case I brick my Emax 25A 4in1 esc and I have to buy new ones, I was wondering how we can tell if an esc supports Pixhawk pwm at 3.3v?
Does anyone know which esc's definitely work with the Pixhawk and wont glitch?
maybe is easier if you contact EMAX support... they might know exactly which ones to remove, with the single one is easier, this one is a bit more complex...
