Title: Miniosd damaged or not know how to configure
Post by: TMGsi on June 03, 2016, 08:55:53 pm
Hello, I need help.

I bought a miniosd and I am not able to work with cc3d revolution. Miniosd installed and only shows the image of fpv without miniosd information.

Miniosd V.2.2

That firmware isn't for LP/OP controllers.

The wiki with the setup info for use with cc3d and revo boards is at https://librepilot.atlassian.net/wiki/display/LPDOC/MinOPOSD+setup

Hello, thanks for the help. But still can not configure. I went on the site and downloaded the firmware to three Revo and did not work.

My radio is in PWM mode

What is Lp/Op controllers?

Please help me.

Today I made a test flight with my Robocat270mm with CC3DRevo, the card is very good. Much difference between CC3d. FPV is also very good. Just missing the OSD and GPS.

LP/OP means LibrePilot and OpenPilot?

if so, where can I find the firmware to work with librepilot?

or better, which will be easier to make the miniosd function in revo?

I gave you the link to the firmware and instructions about 4 posts back.

I think I informed the wrong specification.
I downloaded the firmware you gave me the website did not work.

The especification is written is : MavLink-OSD   V2.2

are different?

It looks like the same one and their web page says it's compatible.

I don't have one so I can't help you troubleshoot any further.  Maybe someone who has one like @f5soh will answer with more info.

Every firmware you can download in wiki page should "work" (i mean osd incrustations), only some options like analog inputs should not match.

Just follow wiki instructions, update charset, firmware.

Be sure the OSD/board is powered with external +5V around 500mA minimum.
Some +5V from some Esc do not provide necessary current.

Please post some pics how you wired OSD

I have the image without the osd information.
follows the photo

the wires as follows site.

I think the esc provides 5v+, if off lose fpv image

Are you able to configure / read / save using the config tool you downloaded from wiki page ?

Just powered alone the OSD should display something, be sure you didn't inverted input / output on video connector.

You should provide +12V on Video connector, that power the video chip in your OSD version, looks like the led is on for video side but maybe underpowered, don't know.
Title: Re: Miniosd damaged or not know how to configure
Post by: TMGsi on June 07, 2016, 09:45:54 pm
yes, record the firmware and the charset.

arfucam osd config 2.1.3.0 (configtool_minioposd.zip)

the site that mention is : https://librepilot.atlassian.net/wiki/display/LPDOC/MinOPOSD+setup

video wires are correct.
Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 07, 2016, 10:00:34 pm
Can you talk with OSD using the configTool ?

I mean do some panel changes and save, read.

Try without video input from camera... some high TVL cameras locks the video chip.

see what shows when I took the input video.

My kit fpv is Eachine 600mw

now is with     LP_All_From_Revo2303.hex
Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 07, 2016, 10:20:56 pm
Looks like the Charset is ok (JR130 character) but the text never comes from LP firmware needed, no way...

You still run original firmware flashed on MinimOSD.

You should use this one for Revolution board.

Post by: TMGsi on June 07, 2016, 10:52:03 pm
see now after I updated the firmware.

I will not be able to use my camera (kit eachine ) in this osd?

to connect the input video the osd desappears.

If OSD stop working while you connect the camera, that a TV lines issue.

The chip used for video is pretty old and do not support 1000tvl camera
Title: Re: Miniosd damaged or not know how to configure
Post by: TMGsi on June 07, 2016, 11:19:18 pm
camera especification: ccd 800tvl 148 degree camera lens

Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 07, 2016, 11:35:08 pm
Or 800tvl in your case.

That a hardware issue, not related to firmware.
Title: Re: Miniosd damaged or not know how to configure
Post by: TMGsi on June 07, 2016, 11:52:14 pm
which camera would you recommend me.

Thank you so far.
for you (@f5soh) and the @hwh

There really isn't a particular recommendation, some of the time the 700 line ones work. The 1000/1200 line ones never seem to work. The chips in the OSD were designed back when there was only regular PAL and NTSC, nothing higher res.  They were primarily intended to overlay camera number/location and date/time on security camera video. Unfortunately the chip industry has decided that analog video is no longer common enough for them to build a replacement chip for the higher res video.

Any inexpensive normal res camera should work.
Title: Without battery voltage information on MinimOSD-Mavelink and Revo controller
Post by: TMGsi on June 11, 2016, 12:13:38 am
Why Revo does not provide the battery in OSD?

What do I need to view the battery voltage in the FPV screen?

Title: Re: Miniosd damaged or not know how to configure
Post by: TheOtherCliff on June 25, 2016, 07:08:34 pm
Most people use a pin on the MinimOSD board, but it requires soldering resistors to the board and some battery connector to the resistors.  Also very important, you must make sure that you are using firmware that has the correct option compiled in so that it works with the MinimOSD pin that you choose to use for this.

Then there is calibration to make it display the correct voltage.

A current sensor door is another possobility?
Where can I find this current sensor?
Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 25, 2016, 08:59:12 pm
Assuming you are using a Revo, you should use the OSD firmware for Revo.

You can setup a quick voltage monitoring simply using a voltage divider with two resistors:
https://librepilot.atlassian.net/wiki/display/LPDOC/Configure+a+Current-Voltage+sensor#ConfigureaCurrent-Voltagesensor-Basicvoltagesensor

Many current/voltage sensors initially designed for APM should work, just be sure the voltage from monitored current/battery voltage does not exceed 3.3V.

Post by: TMGsi on June 26, 2016, 12:04:09 am
I'll make it simple (with the two resistors) until I find the sensor that will provide me voltage and current.

It is for the Revo, forgot to mention.

Now, all current sensors that are encounter 5v. I'm not fiding the 3,3v
Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 26, 2016, 12:25:37 am
They say 5v because some of them provides +5V output to power flight controller.
Title: Re: Miniosd damaged or not know how to configure
Post by: TMGsi on June 26, 2016, 01:11:08 am
I am using battery 3s

so

(12,6v x 2.2) / (10 + 2.2) = 2,27v
not exceed 3.3v

I was confused with the 5v out.
Title: Re: Miniosd damaged or not know how to configure
Post by: f5soh on June 26, 2016, 09:56:33 am
Sure, in wiki example the voltage output after divider is already bellow 3.3V using a 4S battery.
So no issue using a 3S battery.
