Hello. I want connect servo and relay to pixhawk 2.4.8. I use 4.0.3 firmware. I try this https://ardupilot.org/copter/docs/common-gripper-servo.html
But I did not find [GRIP_ENABLE] function.
You do not see the parameter here?
If not post a screen shot of the messages screen right after connection like this.
I did as described in the link and everything work good.
So your problem is solved?
Yes. But now I have a problem with relay in aux5
Is BWD_PWM_COUNT set to 4? (enabling GPIO on AUX 5&6)
RCx_OPTION set to 28? (RC input channel of choice controlling Relay 1
RELAY_PIN set to 54? (Relay 1 output on Aux 5)
BRD_PWM_COUNT set to 4? - yes
RCx_OPTION set to 28? - yes
RELAY_PIN set to 54? yes
I set relay to chanel 8
So is it working or not? Post your parameter file if it isn’t.
You have the RPM_PIN set to 54 (AUX5) also. But even with this setting the configuration works fine for me. Chan8 goes high, 3.3V output on Aux 5.
Yes. Signal coming but i can not command this signal
Is Chan8in changing PWM values? >1800 for Relay on? I have the same configuration as you have on the bench and control from a chan8 switch toggles the relay on/off. It’s a Pixhawk 2.4.8 also.
Yes. What relay do you use?
As I said the same one you configured for. Here is the parameter file if you want to compare it to yours.
