MATLAB: Embedded coder support package for px4 : additional arming method

Question

I'm trying to stabilize my x-quadcopter with pixhawk1.

I builded my coder to pixhawk, however, I want to arm without safety switch.

I want to arm with my RC transmitter stick(move stick like this↘↙).

How can I arm without using safety switch?

Answer 1

you want to disable the hardware safety switch?

if so, you have 2 options:

1.in QGC, in parameters you can disable the IO_SAFETY option

2.you can connect your motors to the aux outputs and not mains

warning: it is dangerous to disable this option...

if you want to arm the vehicle by the combination of 2 sticks (↘↙) , you need to add logical condition in the code

lets say "↘" this is channel1 radio , and this is "↙' channel2, then those signals correspond to pwm input you get from the radio, so all you need is to add im simulink: "if channel1 pwm>pwm1 && channel2 pmw>pwm2, ARM=1 else ARM=0" and send it to pwm block
