Question about CAM_DURATION Parameter

I have a PWM switch hooked up to AUXOUT 1. It is activated like a camera servo from CH8. But because of the CAM_DURATION parameter, I can only keep the PWM switch on for a maximum of 5 seconds. Is there a way to keep the PWM signal high with the came

I usually fly survey missions using Tower on a Nexus 7 tablet but I always have to change the altitude and sidelap settings to get the flight that I want. Is there a way to make a custom camera profile and add it to the drop down menu in Tower?

How do I connect LEA6 to u-Center?

My GPS stopped working after a hard landing. Didn't seem hard enough to break anything though. The red light on the GPS module is lit, but I never get the blue "GPS fix" light.

I checked the GPS in the MP terminal and all the lat/long values are zeros
