The OSD works find after I connect the power to the pixhawk and video transmitter which provide power for the OSD and camera ,but after several seconds,the osd display becomes the attached photo.
the mode change channel in my flight controller is channel 5，and the mini osd control channel is channel 8，so there can’t be conflict in the osd and mode change, to double make sure that , I even disable the OSD channel.but the OSD still like that .
my sequence of connect power is that
first connect the battery power to the pixhawk which provide 5v to the OSD.
second connect the battery power to the vedio transmitter which provide 12V the OSD and camera together
In this way the OSD work as pre describe ,so I reverse the power connect sequece above ,but the osd still disapear after several seconds
after the OSD message disappear ,the screen also have some battery votage display,it’s not sent from pixhawk but from camera which have the votage detect feature.
do any body know what the problem is ?![OSD01|375x500]
