I don't think the OSD software has been updated to support fully the new serial protocol. I'm avoiding any configuration changes from mine because of that.
Does anybody know if the OSD is still supported by MichalM_sk? It is been a great OSD and the development was moving fast in a good direction, but lately is been slow here. Hope everything is Ok with MichalM_sk.

Hi to all, anyone can ask me why my home arrow was always wrong?? And see the Home distance, when was at 652m the counter restart to 0m, was normal?

See the video:

Are you using I2C GPS? There is a known issue with arrow direction and the limit of 650 meters to home. If you search in the GPS integration thread you will find more information. It should be fixed in the next 2.2 version of EosBandi I2C GPS software.

I dont thinl one could expect the dev of the osd to adapt any little change from the mwc trunk asap. the trunk is changing so fast. I think you should give michal some time to adapt the changes after a dev release. You also can not expect it to be flawless. It is a de release agter all...

Yes I2C GPS.

With new version are ok? Yesterday i try but dont works anyway, need some change in the code?

I found more info in this thread:

viewtopic.php?f=8&t=649&start=1570

I see that EOSBandi has a beta ver 2.2, but not sure if that is fixed there. I would post the question in that thread also.

Hello everybody, if somebody will be interesting. when i construct this device i have a problem at first start of device.
OSD does not sync with input signal.

Problem was solved by adjust voltage on pin 6 of LM1881M. It needs to be 1.2-1.22 Volts, no more / no less!

Videoroll of adjusting on link http://www.youtube.com/watch?v=z9XqPIcj0Cc

My rebuild schematic

this scheme needs a Strongly stabilised VCC or use a voltage reference scheme for 1.2V generating.

MichalM_sk - respect for great project!

Hi All,

this project had a little pause but I'm here now with a new ideas.

> First, I will release new FW with support for multiwii 2.2.
> Second, this project will be moved to SVN repository.
> Third, osd hardware will be available again

I am also working on new MobiDrone COLOR OSD.

Welcome Back.

Hi Michal,

Does it possible to add indicator for throttle (configurable by define - on/off) or just to show throttle value (0..100%).
In some cases, for FPV it would be very useful.

Thanks in advance.
Alex

Hi Michal,

nice to hear you're back!
We're really looking for your new release...

May I ask you to split your code into many tabs (ie. serial comm, char definitions, config, etc) to make your code a bit clearer for us? Maybe somebody would have ideas for development...

And also, a vario indicator would be great (sice we have quite well vario calculation and sent via MSP)

Hi Michal,

Just another wish, could you add the option of reading vbat, pmeter and RSSI from MWI instead of sensors via MSP?
Then all of them could be handled via MWI generally...

BR
Adrian

Posted: **Fri Mar 08, 2013 9:42 pm**

+1

vbat already is.

Posted: **Mon Mar 11, 2013 11:01 pm**

Any idea when we might see an update to work with v2.2?

Posted: **Sat Mar 16, 2013 10:24 pm**

+1 for 2.2

Posted: **Fri Apr 05, 2013 5:22 am**

Hi All,

There is still nothing new from Michal...

:(:(
I adore his job, maximum respect. But, the MSP is far old in current Mobidrone Code.
And maybe Michal is too busy with other projects or job, etc.

I'm wondering on if anybody could dig in his code and implement the current MSP?
Unfortunatelly I'm spending my spare time for other MWI code develpoment right now.

Any suggestions would wellcome!

I did do it partly with boxids - and it was a major PITA....
Got it working, but somehow screwed up and decided there was a much easier way

In serial ino...
add
#define MSP_MOBIDRONE 121 // for mobidrone 2.1

create a MSP_MOBIDRONE section same as what MSP_STATUS is in 2.1

in mobidrone, change MSP_status number to 121

Or something like that. Think I had to tweak HORIZON/LEVEL to look same so if HORIZON, then LEVEL...

It works....

I sold mine shortly after to someone who was desperate for one.

I think many people have moved on to the Minim Osd. Because of Micheal's coding style has made it very hard for others to follow what has been done. I am focused to because I build an all-in-one Flight Control based around the mobiDrone. Been busy with other project but I need to get back onto this one soon.

The reason why I prefer Mobidrone is that it doesn't use the MAX7456 OSD chip which has really limited functions! (You can only build any graphic elements from pre-defined caracter table...

)
With the LM1881 built in the Mobidrone we have unlimited graphical freedom, the only limit is our fantasy (and coding capabilities... :S ).

So I'd like to keep Mobidrone OSD on and have MPS support in it!

Posted: **Fri Apr 05, 2013 8:45 pm**

I agree and was one of the first to use it.

I just been avoiding this project hoping Michael would update it.

Posted: **Sat Apr 06, 2013 12:22 am**

Talk about the power of the LM1881, here is a small demo of one of my unfinished projects. Unfortunately, the MobiDrone hardware would require a modification to use the Arudino TVout Library. I stopped working on it because no I talked to seem to be interested at the time.

Posted: **Sat Apr 06, 2013 1:01 am**

I also grabbed a MinimOSD because I was sick of waiting for the code to be updated for the mobidrone

But I would really prefer to go back to the mobidrone.

With the Minim OSD it needs to get all its data from the FCB, I really preferred having Vbat and RSSI connected to the OSD (Mobidrone)

So I hope the code can be fixed so I can swap back to mobidrone

Posted: **Sat Apr 06, 2013 1:18 am**

I think we can do it as a collective team.

Posted: **Sat Apr 06, 2013 4:20 am**

Maybe it would have sucked less if it used a cheaper and more capable MCU.

With minim it's possible to catch voltage and rssi directly:

If anyone wants to build the osd until the boards from michal are back in stock, its possible to build it with this atmega238 board:
http://microcontrollershop.com/product_ ... hmg7uqfp24

You can spare some components if you use this instead of using an atmega alone, and you can flash it comfortably over usb. I managed to put it on a solder board about 6 x 4 cm wide, might still be a bit large to put it on a copter but its enough for testing and development. If someone is interested i can post a complete list of parts.

Thanks again to michal for the nice work.

Hi,
Finally found some time to fly 2.2 today.

Sadly it really rocks and I cannot go back Td 2.1.

So what is the difference between 2.1 and 2.2 MSP?
Is it really hard to apply hat change to Mobidrone? I will do my part if needed and Michail approves.

Nils

Posted: **Fri Apr 19, 2013 8:34 pm**

The basic functions still work example: artificial Horizon, Voltage etc. , just not the configuration stuff like PID setting and Indicators.

Posted: **Fri Apr 19, 2013 8:42 pm**

Richie would you mind writing down a list of which stuff works?

Yes, because it absolutely sucks. Nobody needs that at all today. Simply a no brainer.

Yea it is a no brainer and is why I moved on to a Raspberry PI, who gives a crap what the next guy have or use right? Why would anyone in their right mind waste time writing software/firmware for an unappreciative group of people? No wonder Michael moved on. :shock:

Posted: **Sun Apr 21, 2013 1:17 am**

IS there a list somewhere that details what changed in the MSP between v2.1 and v2.2?

Posted: **Sun Apr 21, 2013 4:25 am**

Yes, in the source code.

Posted: **Mon Jun 03, 2013 2:16 pm**

Hi,
I now had time to fly a little (damn weather - it is supposed to be summer now).
I noticed, that the OSD does not notice arming and disarming anymore - so the flight time counter is not working anymore.

Nils

Posted: **Thu Jun 13, 2013 2:56 pm**

Hi,

the homepage and shop is down, I think the mobidrone Projekt is abandoned :-(

.

Is anyone interested in reverse engineering the code?
Or is it possible to use another osd software like minimosd on the mobidrone hardware?

Nils

Posted: **Thu Jun 13, 2013 3:30 pm**

Interesting and just as expected. It is possible to do both, run other firmware like the DIY OSD but that will not work with MWC. I had started rewriting Mobidrone but give up because of the negativity. Not going to invest my time, the features I need works as is with MWC 2.2.

Posted: **Thu Jun 13, 2013 4:03 pm**

There is a quick way to get it functioning without too much effort. ...
it will give you most features working OK with 2.2

viewtopic.php?f=8&t=1498&start=260#p34329

Sorry I don't have it any more to help, but can confirm it worked pretty good from what I recall.

Posted: **Fri Jun 14, 2013 12:37 pm**

Hi,
I just found out how to get the checkboxes working again.
it is a bad wokraround, but it will do until the msp changes again. The target is the same but on mobidrone side and setup specific :-(

but i think your solutions is better, I only have to change multiwii code.

thank you!

Posted: **Fri Jun 14, 2013 8:02 pm**

Hi,
shikra, unfortuneally your solutions somehow does not work for me.

The arm box signal is not recognized in OSD.

But If I activate headfree, the OSD is thinking the copter is armed.

weird...

Nils

Posted: **Sun Jun 16, 2013 1:38 pm**

Hi,
got it sorted out.

You have to do as shikra said but edit the msp_mobidrone section as follows to send the lshifts corresponding to the old 2.1 protocol.

took me some tries to realize that.

Code: Select all

case MSP_MOBIDRONE:
     headSerialReply(10);
     serialize16(cycleTime);
     serialize16(i2c_errors_count);
     serialize16(ACC|BARO<<1|MAG<<2|GPS<<3|SONAR<<4);
     serialize32(f.ANGLE_MODE<<0|f.BARO_MODE<<1|f.MAG_MODE<<2|f.ARMED<<5|
                 rcOptions[3]<<3 | rcOptions[4]<<4 |
                 f.GPS_HOME_MODE<<6|f.GPS_HOLD_MODE<<7|f.HEADFREE_MODE<<9|
                 f.PASSTHRU_MODE<<8|rcOptions[BOXBEEPERON]<<10|rcOptions[BOXLEDMAX]<<11|rcOptions[12]<<12|rcOptions[BOXHEADADJ]<<13);
     break;

Ah sorry Nils - forgot that bit! 2.1 order + the 2.2 flags. Memory fading....
I do recall putting an extra bit in to make horizon look same as level in the msp_mobidrone bit too.

At least you have a working one! That great. Might be worth posting source or link to full list of points to change.

Posted: **Mon Jun 17, 2013 7:14 pm**

No worries mate. I figured it out eventually. And I learned a bit about MSP this way ;-)

Hi,
I have downloaded project's codes, I need it for my project but I have problems with "interrupt routine Hsync" part of code. I couldn't understand it.
In my project I want to modify codes to show a dynamic graph of an analog signal. I would be grateful if you could help me.
thank you in advance

You would be better served by using the LM1881 version of the DIY OSD from which mobiDrone originated from. Plus Dennis is a very Friendly guy and will help if possible.
