Target Request-Matek F405-OSD

[SilentZen]

http://www.mateksys.com/?portfolio=f405-osd

Tested it with betaflight had 5 usable uarts, neat attachement to power distribution board which has current sensor (FCHUB6s), OSD, SDCard Slot.

Looks like a good replacement for omnibus.

[digitalentity]

It's already in progress https://github.com/iNavFlight/inav/pull/1716

[MaxFpv]

When will the release be available?

[digitalentity]

@MaxFpv quite soon!

[JulianGoesPro]

whats the benefit over the Omnibus?

[SilentZen]

In my case the matek powers but omnibus does not, but seriously the Dev gets pinged when comments are made here and what makes one target better than another it's just a time waste.

[teckel12]

Odd that they didn't include a barometer, however.

[digitalentity]

Done (less I2C/baro/compass), usable for a flying wing though.

[stronnag]

Plans for I2C?

There are a number of users (including me) who would like to use the F 405 AIO (I2C pads exposed) with iNav on multirotor.

[digitalentity]

@stronnag my sample of Matek board don't have I2C pads (V1 of the board). I'll make required changes - would be glad if you can test them.

[stronnag]

Thank you. I'll be pleased to test the changes, I should have the board within a week or so.

[digitalentity]

@stronnag then I'll suggest we close this and open a new issue "Add I2C support for Matek F405". 1.7.2 will be release w/o i2c support, but we'll have it added as soon as possible. What do you think?

[stronnag]

Good idea. The obvious title may prevent multiple issues.

[McGiverGim]

If I'm not wrong, there're not a board version with I2C. Some images around internet shows a version with I2C pads, but I think this was a first version that never was sold. The real board that you can get has a DAC pad in place of the I2C pads.

[sammichael25]

Would this also work on the Matek F405-AIO

[digitalentity]

@sammichael25 if CPU pin mapping is the same - it would. I don't have the AIO board, so this isn't tested. If you have the board - please give it a try and report back.

[stronnag]

AIO baord is wokring since https://github.com/iNavFlight/inav/pull/1920

They are the same electrically, the AIO exposes the I2C pins.

[stronnag]

And, if you need it, there is a working (flight tested) hex file at http://seyrsnys.myzen.co.uk/inav_dev/ (from 2017-08-19). It will be updated once #2041 is tested / merged and #2028 is merged.

[sammichael25]

Ok thanks...Also what pins do I connect the external baro and compass too..do they both go on the same I2C pad? And can sonar be added?

[stronnag]

Both mag and baro to the marked SDA/SCL pins (by the SD card). Clearly marked on the vendors documentation. My favourite iNav board ATM.

[sammichael25]

I did that but cli status says Mag Unavailable....the mag icon on top is also red

[stronnag]

We really need more that "doesn't work" to help debug the issue. Can you please provide:

• Brief description of the external devices you are using
• A CLI diff
• The output of the CLI bootlog command

For comparison, there's a working diff at http://seyrsnys.myzen.co.uk/inav_dev/nav_f405.txt (BN880 M8N GPS+HMC5883 and BMP280), the bootlog looks like:

I am using Matek F405 AIO, UBLOX M8N with compass HMC5883L

Also can you please tell me which pins I have to use to manually turn servo

Thanks (excuse me reformatting a bit). If I apply your config to my machine, it finds the mag:

Is the mag detected in Betaflight (the latest dev βF hex supports I2C on this board) ? Are there any I2C errors?

[sammichael25]

Ok it is detecting now. Im not sure what went wrong. My last issue is controlling the gimbal. Im not sure which pins are mapped to servo 0 & servo 1.

[stronnag]

Currently, there is a single multi-rotor servo defined in the target (on S1). I have no idea if this works.

[sammichael25]

Is there a command to move the servo output to another pin? With servo gimbal feature enabled I cant use S1 for motor 1 and I don't know what other pin I have to move the esc wire too.

[digitalentity]

There is a hardware limitations to possible pin assignments - that's the reason why resource remapping won't be available in INAV any time soon - it will create more issues than it will solve.

When pin1 is used to servo all motor outputs are shifted - pin2 is motor1, pin3 is motor2 etc.

[sammichael25]

I tried that but only 3/4 motors work. Motor 4 which was moved pin 5 doesn't spin. I even moved it to pin 6 and same result.
