So I got a micro Minosd for my 250. I am using the latest Minosd configure software thru an FTDI adaptor. I have flashed the 2 different firmware virsions and updated character file. When I plug everything in and check display, the screen layouts are not what I selected. It also does not seem to be getting any data from CC3D. I have checked all the connections with continuity tester and have tried switching RX and TX pins. The CC3D port is set to OSDHK. I was able to get battery voltage although "batt 1" and "batt 2" where reversed as labeled. I should also mention that I have tried both main and flexi ports on CC3D with the same results. What am I forgetting?
-
Did you use firmware from here ? :
https://librepilot.atlassian.net/wiki/display/LPDOC/MinOPOSD+setup
Osdhk is a old stuff, you only need a port set to telemetry and 57600 baudrate.
-
Yes, I tried both firmware versions. I will try the telemetry setting on the baud rate you mentioned. Any ideas about why the OSD is not taking the screen changes I chose? I also cannot change the screens from panel 1 to panel 2 with acc.0 switch set on Ch 6. This is why I am sure that the OSD is not talking to CC3D
-
Since you get some alarms like DISARMED, MAG ALARM (the text blinking) you can't switch between panels.
This include the "No TEL COM" alarm :)
Because when a alarm occurs, osd switch to the right panel to tell user about the warning
-
I get no alarms, no text, no horizon movement,
-
Did you put the "Warning" object ? (The OverSpeed text in my screenshot.)
It can be hidden if bellow other object...

I get no alarms, no text, no horizon movement,
Screen is blank ?
-
No, Screen has voltage at top middle, Horizon low middle, Timer upper right, Sat's lower left. The voltage connects directly to the OSD so I have that figured out, and the timer begins counting up after boot. Nothing else moves
-
Double check how is connected, you can choose port you want: flexi or main but 57600bauds.

all is connected as pic shows. Telm on port @ 57600 was the trick to get them to talk. Note: the OSD will not communicate with CC3D when usb is connected between CC3D and LP GCS. Fast blinking green light turns solid green. Function returns when USB is disconnected. Still working on this: OSD does not show the screens that I set up in config software. Data values and positions are not as I set.
-
When USB is connected the telemetry stream go to usb.
Before trying to get panel switching you need a link: horizon that move for example.
Double check wiring, try the other port.
Post a good picture ?
-
I will post a picture this evening of the setup. I do now have a moving horizon and changing pitch degree angle. And the CH6 switch does do something,however the screen setups that I made in OSD configure tool are not what I see when OSD is running. Almost like it has a default setting.
-
If osd talk with board, no need a picture.
Did you found the previous issue ?
By default the first panel is active.
-
Yes it is now talking with the board. The change in the port from OSDHK to Telemetry @57600 plus board reboot fixed the communication issue. I have a 2 position switch on CH6 for panel change. In one position I get the data that I told you about in the previous post and in the other position I get no data at all. Neither of these is what I had set up in the OSD config tool.
-
Ray ,
Make sure that on the config tab you have the panel switching set up correctly. I now have mine working fine, including battery volts to within .1 of a volt. Horizon and mode switch. Good enough.
-
I will check again, but I'm sure that I do have that function set on CH 6 in config tool.
Strange thing, every time I open that config tool it seems to be different. Even without the OSD or FTDI connector plugged in. I opened it the first time and had the backround PIC that was shown in the screen shots above along with many previewed values. Next time I opened it, no backround picture. I also had no sample text or values on the screen. Than I downloaded it again and was back to having text and a backround picture. I could move the text around and add or remove things as you would expect. Then I tried to open it again the next day, and again no text or backround image. Weird huh? Wonder if this has something to do with my problem.
Thanks
-
Exactly what is that OSD? They are calling it OP OSD.
-
Mine is Micro MinimOSD w/ KV team mod. It very well priced, small and on paper should be just right for a 250 machine. I just need to figure out why the setup tool is acting strange and why the OSD is not displaying the panels that I setup. What it DOES display works very well.
-
Maybe are you using various config tool versions ?
Be sure you use the one from Wiki page.
-
Not set my minimosd up yet but have this bookmarked for later reference

"Good Enough" That's where I'm going to be soon
I thought I had the volts calibrated correctly in the setup screen accessed thru the OSD on startup, but I guess I don't. It keeps changing by itself. I set the value up to reflect what a volt meter says the voltage is at the battery, then I exit the setup screen and the displayed voltage is different.
-
Well I have successfully set up the minimOSD to the CC3D. Had a glitch of disappearing OSD info when camera plugged in, but fixed it quick by changing to PAL.
All of the OSd information is correct. But.... When the quad is tilted left or right I get Chinese garbled junk only in the horizon. Is this fixable?
IS this a Character set issue? What should I be using?
-
Yes, update the Charset.

Hi Guys,
I noticed that you are discussing some connectivity issues on the minimosd in this thread. I was wondering if anyone could help me with another small challenge regarding the same topic.
I´m using the CC3D Atom just to bring up some telemtry data re. vehicle orientation and direction on my fpv goggles. The CC3D is not used as flight controller (I use a separate flight controller on my 550 FBL Heli)
I am utilizing:
For configuration of the CC3D: librepilot rev. 15.09 ,
last revision Firmware downloaded and installed via librepilot.
OSD configuration tool: ArduCAM OSD Config 2.1.3.0
Character set: Charset_1_3_0.mcm
Firmware: minOPOSD_15_02_plain.hex
Now this is the issue:
Telemety data is sent via CC3D Mainport to OSD.
Horizon, and angle values for Roll and Nick are displayed correctly. The compass data (heading) however is not displayed on the OSD. In OSD configuration "Heading Rose" and "Heading" are switched on, but these data are not showing up on the screen.
librepilot "Flight Data" Tab and "Scopes" Tab are displaying sensor data for YAW. Seems as if a compass signal is present...
Do you have any idea on how to bring the compass data (alias Heading/YAW) on the OSD?
Any idea would be greatly appreciated
-
Hi,
CC3D do not have a Mag sensor, the only way to retrieve heading data is a GPS that give heading from path trajectory... better with a fixed wing, not accurate with Multirotor.
https://librepilot.atlassian.net/wiki/display/LPDOC/Configure+a+GPS+for+CC3D
If some extra data is missing on OSD you can update osd firmware, some UAVO have changed in rel15.09

Welcome,

Thank you Laurent,
I will check Firmware and if neccessary change the controller.

I got my micro Minosd to work correctly now. I had an issue with the battery not displaying the correct voltage, even after I calibrated it via the OSD. I reloaded the firmware and recalibrated the voltage again and now it seems to be working correctly. It is also displaying GPS data, home arrow, and warnings now. It will not display even zeros for GPS data if the GPS is not plugged in and properly configured. I was thinking it would still have a ZERO next to ground speed and altitude if no data was received. I was wrong.

i have a cc3d with librepilot and i try to add a micro minimosd,i flashed the firmware and charset,i ve got all connections right ,main port telemetry and 57600.All are working nice i have osd at my goggles but voltage and amp readings are wrong.I use 3s battery and i see a 17.20 volt reading.I have tried also the kvmod micro firmware and i get 0.01 v reading.All the other readings are working fine,warnings,throtle,horizon and tilt line....all ok exept voltage and amperage.I also have tried to connect bat1 and gnd pins to my battery but i get the same reading.
-
Using the analog input firmware version you need to calibrate sensor (voltage and current)
Move the toggle switch just after boot to enter Setup menu.
-
I have found the menu but can't understand how calibration works.Is there a calibration guide or a tutorial video for that?
-
Yes, on the librepilot wiki there is a calibrate voltage/current sensor howto, I can't seem to get a link to paste but it is an easy to find page
