1/ Software Update on the integration of Remzibi OSD and APM
I do not know how to make a firmware for APM Planner, so you will need to use Arduino GUI tool
Replace your ArduPilotMega folder with the ArduPilotMega folder from APM2.1.2-OSD.zip: APM2.1.2-OSD.zip
Configure the APM_Config.h to your need
//to deactivate use OSD_PROTOCOL_NONE
//#define OSD_PROTOCOL OSD_PROTOCOL_NONE
#define OSD_PROTOCOL OSD_PROTOCOL_REMZIBI
// port 3 is the telem port on the shield
#define OSD_PORT 3
// set a radio switch to activate/deactivate the OSD output :
// below 1450 will display the OSD
// above 1450 will stop displaying the OSD
#define OSD_MODE_CHANNEL 6
// choose your unit to display the disctance to waypoint in feet or meter
#define OSD_UNIT OSD_UNIT_METER
//#define OSD_UNIT OSD_UNIT_FEET
Then follow the normal process from the wiki above.
To connect your APM with the Remzibi OSD, you need to have a cable from Telem port to Remzibi GPS port. GND and TX (from APM) are enough.
If you do not see any OSD info at first, stop your camera feed to see if the OSD shows up anything. You might be starting in the wrong TV mode (PAL/NTSC). You just have to push the OSD button for about 1 second.
Note: for metric or feet units , be carefull to use the right unit in the Remzibi OSD software. You need to change the APM_Config.h for feet/meter of the next waypoint in the status at the bottom
Once everything is connected, normally the APM sets HOME for the OSD once it gets a GPS_fix. If you connected your OSD after that, then you can just push the OSD button once to force the HOME location on the OSD.
The arrow and distance from home will always display home direction and distance to home direction. It won't show the next waypoint direction (too complicated yet )
5/ what's new
I have updated all the units and it should be displaying proper values now
