background story

The RX5808_pro gave greate features and usability to Boscam rx5805 based receivers. It was easy to build, low cost and easy to adapt.

A lot of users took it and improved there equipment with is. A great success story for all contributors for this nice open source Adruino project.

But: I had always the wish to have the TVOUT not on a separate input on the monitor, but as OSD overlay. No switches to change from settings to video.

I did a lot testing how to mix efficient the TVOUT with the video from the receiver. The end of the story: To complex to build and tricky to handle (internal / external video sync). Therefor I abandoned the "OSD" extention for the rx5808_pro.

Than in the summer of 2015 I had some time to improve my copters. I wanted to replace the stand alone OSD by minimOSD board and attach it to the NAZA lite. There is a great open source project from TeamRedFox001 (minnazaosd).

When I looked to it the idea rose: Why not controlling the RX5808 with a minimOSD board?

PRO:

  1. Arduino
  2. OSD chip
  3. Power supply (switching one)

CON:

  1. No real grapics
  2. Lack of IO pins on connectors
  3. No USB

Since a OSD does not support any "graphics" everything is done with "custom" characters. All the other minimOSD projects gave all the background how to build a "custom look".

A new project has borne. Since google code is gone... its on github now.

RX5808_pro_osd !

Two weeks later all was done.

I almost rewrote all the code to make it lice looking based on Character OSD. Some new features has beed added.

Now its time for you to build your OWN!
