The setup is a camera trigger via the relay method.
The firmware is Arducopter latest release (as of today).
The test configuration is the following:
-BRD_PWM_COUNT set to 0 (so all of the 6 AUX outputs can be used as GPIO for relay)
-Camera trigger type set to relay
-Relay 1 set to GPIO 50 (AUX1) - I also tested with Relay 1 set to GPIO 51 (AUX2)
-Camera cable connected to AUX1
Test is using mission planner “Trigger now” function on the world map.
Result : nothing happens.
If i test with Relay 1 set to GPIO 52 (or 53, 54, 55), it works.
So is there a bug in the firmware that does not allow to use the first two AUX ports as relay outputs ?
Hi. Im dealing with this issue. I’m using version 4.3 with cube orange. Trying to get a GPIO setup on aux 5. Set servo5_function to -1. Set up a switch on channel 6. Set rc_option to 66. Set relay_pin 5 to 54. I get 0v on aux.5. Checked all aux channels as well. I have a pwm relay i can use but i would really like to make this work. I read all the posts associated with this problem with no luck. Please help. Thanks.
And ch6in? You can also look at the Setup>Mandatory Hardware>Radio Calibration screen for Radio 6. You should perform another Radio Calibration anyway and flip that switch when you do it.
