what is the mean of "fw_osd"
« on: December 24, 2015, 12:55:59 pm »
According to the infomation of "make help", "osd" is board.
But "make fw_osd" build meassage shows that "fw_osd.opfw" comes from some "stm32f4" source files, it looks like the "fw_revolution.opfw" files. I know the osd mcu is ATMEGA328P, so I can not understand the build meassage, can you help me?

What is the "osd" board?
And how to use the "bl_osd.bin", "bu_osd.opfw", "fw_osd.opfw" please?

When I use the "LibrePilot1509 GCS", my osd display gps info correctly, but "LibrePilot1509 r154 GCS" failed, is the problem revelant to "fw_osd.opfw"?

Looking forward to your help, happy jingle bells!
Best Regards!

OP never released the OSD board.  This fw_osd is basically useless for most people.  You probably have a MinimOSD board and should look up information in the LP wiki about setup for that.

I get it. Thank you for your reply.
Is the OSD board used for decoding video signal by software?

OSD board adds some information display to the video picture from an FPV camera so you can see the information while you are flying FPV.  Like a fighter jet display.  Things like current altitude, speed, compass heading, direction of home, battery voltage...

The schematic was published in the openpilot forums back in 2011 but l didn't realize it until I was doing research on archive.org after the forums went down and found the link to it.  Unfortunately archive.org didn't archive the pdf of the schematic and it was lost when the forums went down.  Maybe someone still has a copy?  I'd like to see it too.  (I found it, see my next post)
