    Hi my friends ! I have my RunCam 2 4K and ready for Flying on my DIY drone .
    The thing is that I’m using a pixhawk 2.4.8 as fly controller, and I haven’t been able to control the camera neither the FC nor my RC fs ia6b .
    Please , is it possible to do the same as with Betaflight . I can generate pwm and it seems using uart.
    Thanks in advance .
