Programming erSky9x, need some help (QQ 250 quad).

Post by bob195558 » Thu Jan 10, 2019 3:38 pm

I want to Arm and Disarm using the Throttle Switch.
Which I believe can be done with some involved programming.

I am using the Thunder QQ Supper flight controller which operates for Arming and Disarming
the motors by Throttle and Rudder stick position.
Which are Throttle Down and Rudder Left to Arm and Right to Disarm.

So I believe it may be possible to have the Throttle Switch, when Off
to have the values for the motors to be Disarmed.
(not sure when booting up the quad I can have the the Rudder in the disarming position, may need to check this out)
And when the Throttle Switch is ON, to have the values to Arm the motors
for a set amount of time when the Throttle Switch is first switched ON.
The set amount of time to Arm the motors is so the Throttle and Rudder stick controls
can take over after arming is completed.
Then after flying is done when Throttle Switch is moved back to the Off position, it will Disarm the motors.

List of Hardware

Standard 9XTreme Radio using erSky9x firmware

External XJT module with Dip switch 1 ON (up) and Dip switch 2 Off (down)
which I believe turns it into a DJT module (PPM protocol).

As a start:
Set up a logical switch:
L1 1-shot THR 2
When you switch THR ON, L1 will turn on and stay on for 2 seconds
Then use L1 to control 1 or more mixes:
CH4: +100% RUD
R -100% HALF Switch(L1) - A replace mix.

So, when you switch THR on, the rudder will go to -100% for 2 seconds.
Add other mixes for the throttle.

Thank you Mike.
I will post the results when I have had some time to work on it.

I like using the Throttle Switch as a Safety Switch, but with this older QQ Supper Flight Controller,
when I turned Off the Throttle Switch with the motors Armed,
the motors do not turn Off,
but speed up and I have no control over them, throttle wise.

So I am hoping through programming to make the Throttle Switch able to shut the motors down for Safety.
