Hello experts, I finally got my micro mimosd working, configured and I see an overlay on my video.

However, I connected the OSD to the flexiport, selected telemetry and rates/speed are set like on the wiki page. But nothing happens. I mean it's like there is no communication between both. My artificial horizon stays level when moving the quad and switching flight modes isn't seen on the OSD screen. I have the 4 wires with tx and RX correctly connected and the OSD is flashed with the firmware from the Librepilot wiki.

What am I missing?

Thanks.

Philip

Please post a picture with wiring and config file.
File > Export UAV settings

here is the UAV file

And Here are the pictures.

Your wiring looks ok, try using the Mainport for telemetry.
Double check if the pins inside connector are ok.

Will try that, is the UAV correct?
To be sure, it has nothing to do with the firmware on the OSD? Which is the KV team mod version.

Could you help me as well with my current sensor? I hooked up ground to ground, I to current and V to bat1 on the micro minimosd.
I get strange numbers and readings and I guess I need to configure something somewhere.

It's this one:

You need to enter the Setup screen and calibrate Volt and Amp.
Channel toggle allow you enter Setup Screen just a few seconds after boot.

Is the wiring correct for the current sensor, I think it is but better safe then...

Thanks for you help, yet again.

ok, got it to work, but im going nuts about setting the voltage and current settings in the osd setup screen, i mean how do i start with this, i can change the number but get not whats needed, i have the current and voltage sensor from above, using 4S 1800mah lipo. there are no videos on youtube i can find explaning the numbers or how to calculate. onthe wikipage, its only for the regular minimosd, im using analog inputs from the sensor above. would appreciate a lot if you could guide me here.

[f5soh]

You don't need a video for that.

1 - Adjust "Volt div ratio" value to match your battery voltage.

2 - Adjust "Amp per volt" to match the amp measured while current is around 10A for example
3 - Adjust "Amp offset" to fine tune the "idle" current while motors are stopped

Note you can go from 2 to 3 and return to 2
This can be easily done with a PowerMeter as reference.

Here is a small video of the current situation. My voltage is all over the place, and I have negative amp reading even in setup when I go to negative numbers in amp per voltage the measured amps stay at -0.65amps

This is going from excitement to frustration.

Thanks for your help.

Is it correct that I only have current draw, not mah used counter function? If I so and I wanted a mah counter as well what sensor do I need to ad and connect to the Micro minimosd?

Thanks, Philip

[f5soh]

There is already a mAh counter with the arrow logo on bottom.

Be sure you wired the right input, there is two bat inputs maybe bat2 is the right one.
Also consider you don't have big current changes if you start motors without pros.

How are your values in Setup screen ?

[Jeuke26]

Once I get back I'll post some pics of the setup and the readings.

I already figured out yesterday that I needed to use bat2 connection as the other one was reading almost zero all the time.

And I noticed when I did throttle up and down quickly, my OSD overlay disappeared. The OSD is powered by the main port from cc3d. Does is need its own 5volt, if so I'm providing it twice?
