I want to make an agricultural drone with Pixhawk 1. There is no progress in the sprayer scheme. I have a pump with esc for pump. Could you tell me how to connect to Pixhawk?

No, no wiki yet. You``ll have to wait until 4.1.0 gets released.

Thanks for the interest.

I connected pump esc to aux1.

SPRAY_ENABLE 1

SERVO9_FUNCTION 22

RC9_OPTION 15

The pump is not working.

When the pump esc is connected to the receiver, the pump is operated.

How can I connect to aux1 and operate the pump?

28

is there any estimated release date for 4.1 stable ?

@UPstone If you are using ArduCopter 4.1.0-dev you need to activate the pump using a mavlink command or a mission command. Manual activation with RC9 is not possible when you select SERVO9_FUNCTION = 22

If you are using ArduCopter 4.0.7 then you should set SERVO9_FUNCTION = 1
And you must manually control it.

The OpenTx guys have the best answer to that question. “No” :slight_smile:

32

servo9_function 1 is “Rc pass thru” … right?

33

Depends on which fw version you use

34

I use 4.0.5

4.0.5 servo9_fuction 1 is RCpass Thru

and function 22 sprayer pump menu does not appear.

35

For that version please follow the instructions on Crop Sprayer — Copter documentation
