@Olaf Cool - sounds like you're getting there! No it doesn't currently smooth MSP. Assumption is for all FC data that whatever comes from the FC is accurate. Maybe try using a RC filter to smooth it a little. Same as what the PWM RSSI guys do. Also the supply to the OSD chip must be as smooth as pos...

shikra

MSP - Yes - I think can be done quite easily. I'll drop you a suggestion tomorrow

GUI - yes. I'd like to leave current method as it has value. See if can squeeze in a button for next release

shikra

Sure would be nice to have those settings on the GUI bit like the camstab and servo ones have migrated

shikra

Cool! got there in the end. You had me puzzled for a while - but on a positive we have updated documentation and save memory saving from when looked at the code

shikra

@schnupperm - I'm not quite sure what it does - can you describe a little? Seems to display deviation between heading and direction copter is facing??

shikra

@o_lampe Looked at your photo and I think you have the current sensor connected to the multiwii controller. If that is the case then you have to do all the config on the multiwii FC itself. All the OSD does is display the value the FC sends it. It makes assumption that it is set correctly. For Clari...

shikra

Just to clarify... where is the sensor connected? to the OSD or to Multiwii FC ?? I assumed it was the OSD.

If its the multiwii FC then everything I've said is crap... lol.

I had a quick look at the datasheet and I think that one: Is Bi-directional Requires a 5v supply to the sensor Has an offset of 2.5v I'd suggest... Must have reference voltage set to 5v - or a 5:1 resistor ladder to drop voltage down to use 1.1v reference Make sure it has 5v supply if its needed. Ch...

shikra

@ Olaf - which sensor? bi-directional can be a bit odd sometimes

@roderz -Can you check the MAC fixes in the FAQ .....

I'll add an option for MinimOSD as default... in reality it will do nothing For GUI - try downloading 1.2 again. I made a small change to the GUI only. Mainly cosmetic, but one bit may help Also - turn off the simulator may help speed up any gui response issues when making config changes. ----------...

shikra

OK - let me give a better answer than last time !!! The OSD is completely dependant upon the Flight controller for the "compass", heading, and direction to home arrow. There are two values it gets from the controller - heading and angle to home. Under normal multiwii code I'm 95% sure it n...

Hello

MW OSD R1.2 is now available to download:

As well as software, some other amendments:

@olampe - to enable reversing is possible, but would require the font file to have normal fonts + reversed fonts. Easy if you kept display to text only and limit the non text font. Also would need to reverse the character positions on the screen + a small read of the select pin. Its not difficult - ...

shikra

@chilau - no sorry it relies upon the mag data from the FC. @fastrack - probably overthinking it a bit! Alll need to do is adjust the OSD so the the OSD displays the same as the amp meter at somewhere around the hover point. Its an approximation so not going to be as good as a hardware sensor. That ...

What you mean is autoquad calibration and code design is superior? It certainly seems to be.... For multiwii etc. probably depends on your copter layout, how much it draws and requirements....

Just to update - tested navigation this morning with latest dev version of multiwii R1705 and it worked good. 26 points through to an excellent autolanding.

Question: How do you do the virtual current sensor cal? Do you just mount a current meter, hover at a safe distance and read the amp meter display (the weight of the current meter would effect this value slightly)? I've looked all over but I can't find how to enter the data obtained into the gui......

@Jaames74

I think the Mission waypoint / steps are working OK on OSD now
I had a very quick test flight in garden and it looked good.

Have a 26 step mission planned for monday. Will know for sure then!

shikra

@fastrack - thats really interesting feedback. What you describe with CRT/LCD directly relates to what I suspected - not detecting every other interlacing frames. Cuts line thickness in half + effect of 50% brightness. Just to confirm - is that setting on the camera?? if so can you describe where? Y...

shikra

@tungsten - thanks for the offer - can you pm me an email address and I'll send over some instructions to hopefully compile it into a proper app.

No idea about that file name stuff ... I wouldn't know how to do it if I tried on a MAC !!

Is should changed during mission execution. It always contains the number of the current mission step. Thanks. I think I figured it out.

@ Fastrack. good to figure out the issue. a few have been caught with that one! For the dim characters I am not aware of a fix for that yet. I think I understand the issue. Pretty sure that its ignoring start of new frame so only every other frame shows the image. Therefore its running at 50% bright...

@ EOSBandi - am adding some support into MWOSD for your navi software. Just to display waypoint / step no and that is on a mission. MAybe a bit more later.

I tried to initiate a mission from rest (with the throttle closed) but the props just spun up to what I suppose was MINTHROTTLE (1100) and it just set there. I assume this is a safety feature to prevent an inadvertent take off by mistakenly moving a switch. If so, I think that this is the right app...

Flew my first mission today. No tuning of baro PID or anything and it worked well... Congrats to EOS for implementation.

@ Subaru - no probs - although double check your failsafe works as expected.

Now who would that be

shikra

Just to add...

For anyone daring to try the 1.2 pre release

It will clear previous saved settings
Ensure you choose correct pal/nstc for the cam or may get no video!
You will need to browse and upload new font file

Just uploaded the latest dev with a mission planned. Fingers crossed...

shikra

Definitely not for 1.2

Maybe for 1.3 if plenty of resources are free. I did have a look and its OK to do, but ther eare a couple of downsides - slowing down the rest of the data coming over serial + memory it would use.

I'm not sure how popular the need will be. Will be interesting to see feedback.

shikra

Hi all - hopefully this is the final pre-release / test version for 1.2 Bugs raised and a couple of others fixed Also has support for changes to MW 2.4 serial MSP And in particular it has some support for the 2.4 waypoints - at the moment indicators only to show its in mission mode or landing mode. ...

@hypermobile - no idea. I've had a look through it and the changes for it don't seem like they would cause any issues.

Hello - probably 2 weeks.
Its delayed a little because the EOSBANDI GPS nav is now added in for MultiWii 2.4 release and I would like to add some support into MWOSD 1.2 if possible.
I have added some of the code - need to test fly.

Ok, sorry about this but reeeeaaaaally stupid question time. Is it possible to integrate a simplified MultiWii FC onto the MinimOSD hardware, while maintaining some OSD functionality?

What is the need exactly - I ask because I don't really have the need for this functionality and I'm programming and messing with OSD and FC all the time!

shikra

Reboot is less code!

Someone will have to do the FC code too

shikra

If someone amends the baseflight / FC code with an MSP to disable OSD I'll add it in....

If no particular MSP in mind, Suggest MSP ID 220 with single byte of 0xFF. I'll use this as the suspend sub-command. If want can use 0xFE to re-enable.

Compiles for me. I may have had to do something else like add a library or something
Although compiles and works on PC I have never had it work successfully for me with a MAC ...

Only thing that worked for me is the MAC running on a PC in a virtual machine.

No worries - not the first or last

ABL has produced a version with bigger fonts etc..
I have loaded and it works. He advises a few icons are still original size.
