I'm currently attempting to add a minim or mavlink osd, (whichever works, i have both. Currently the mavlink as it seems to work better, but it is also possible the minim is damaged) to a qr x350 pro. I have it connected and almost working. I have video, and osd overlay, but the data does not update as it should. Only flightmode will update reliably on the osd. The rest mostly stays at at zero. If i connet to mission planner using usb, i can get the osd to update properly(or very close to it, i cant be 100% sure). Im not sure if i can make it last in flight, but either way this is not a viable solution as i'm not using missionplanner in the field. I just want the osd..
I have it connected like this:
devo-m rx ---> osd rx
devo-m gnd---> osd gnd
devo-m 5v* ---> osd 5v. (*5v from the component right above to the RX label on devo-m, according to the pic in this thread)
I have bridged the two sides on the osd, running both digital and analog side directly from devo-m 5v. Video is connected using only ground and vin+vout on the analog side.
I have not touched any resistors or done any other modifications. There is much back and forth about those in this threat and frankly my head is spinning a little
Is resistor mod needed for OSD to function properly, or is that only for two way communication? ( i need only one way for osd, right?)
edit: works fully now, but only after rc transmitter is turned on. Did try the "enable telemetry" button in mission planner, but its unclear to me if that button does anything as theres no feedback. Also altered some sr0 parameters. either of those could be it, Or, it could have been working all along, and i just didnt turn on the transmitter.. running firmware 1.7 for devo-m, downloaded from walkera-fans.de, in case that is relevant.
