Forgot to add :

You need to change the following if you want the OSD to show Meters or feet

int nMeters=0; //Change this to 1 for meters, 0 for feet

Is it posdible to configure the osd layout bin as usual in Remzibi software? I cant seem to change the position of the mode switch display.

Comment by Matthias Badaire on May 18, 2011 at 12:36am

The mode switch display is not a standard remzibi information, therefore we have to add it explicitly in APM code.

void print_osd_data(void)
{
     ...

        SendSer("$M");
        SendSer("83"); // Hex Column (01h - 1Eh) for small fonts add 80h (81h - 9Eh)
        SendSer("0C"); // Hex Row (01h - 0Dh for NTSC, 01h - 10h for PAL)
        SendSer("E9"); // Hex address of First Character
        SendSer("00"); // Hex address of Last Character

 

Column 0x83 - 0x80 (small font) = 3

Row 0x0c = 1

Hi Matthias

Thank you for the update, I just finised installing Ritchie awesome camera code and next step is the remzibi library , one question do you think the Simple osd connected in the same way will work the same?

 

Regards

Johann

Not quite sure which "Simple OSD" you are talking about (Flytron ?) but currently the protocol being used is Remzibi specific and would not work on anything else except if it specifically programmed for.

I am begging Flytron to release an open source version of his firmware to make this possible but to not avail yet.He is talking about summer or after summer.

There should be way to send NMEA sentences from APM to any OSD but we need to know what each OSD needs (NMEA protocol is extremly flexible)

Intresting I didn't know flytron stuff was closed source ? makes me look different at things now, is there a way to add a display on the screen to show signal strenght of your Radio, Telemetry and video link ? like the Telemetry heart line of HK*GCS ? 

Comment by Matthias Badaire on May 18, 2011 at 5:48am

Don't get me wrong, the OSD is meant to become open source in the future. Flytron is commited to open-source (look at open-lrs) and I have huge respect for them thanks to this and bought lots of stuff from them. It needs work to make it arduino compliant though as it is low-level closed-code for the moment

Currently I used the telem port for OSD and it do not if using xbee stuff at the same time works on not. some people may have tried.

Remzibi OSD accepts analog input like RSSI to be showed on the screen out of the box (check on RC group).It should be possible to route all the RSSI signals through the analog port on APM and display them on the OSD as well. I am just not sure about the advantages of doing this.

It looks like you might have your pitch and roll negative. The artificail horizon is backwards.... but that's an easy fix.

 

Nice work!

The video is outdated but the code is ok. I flew yesterday and it is fine, the AH is correct now.

Developer Comment by Mark Colwell on May 18, 2011 at 8:32pm

Glad to see you fly with OSD !

You can add pins to port 0 send TM down to GCS. I send at 38400 but 57600 will work too.

Good work!
