It sounds similar to the 6 way switch which is already implemented in the GUI. The difference is, that people use an analog knob instead of many switches. Or they have a TX with a 6 state turnswitch. The benefit of using separate switches is, you don´t have to go sequentially through all states, whi...

o_lampe

The point is to eliminate the need for a separate channel on the TX, regardless of the way your retracts work ( servo or servoless).

Hi Folks, more and more frames come with retractable landing gears. Instead of using a separate switch on the TX, it'd be nice to fold/unfold it automatically by baro/sonar/land-switch . The SW would need a threshold ( say 5m above ground ) and maybe two variables for top/bottom servo angle. What do...

@josepo
It's probably the compass giving you false reading. Did you calibrate the compass outdoors? Did you check the mag heading with the GUI at zero throttle and full throttle? ( Fix copter to the ground )

Sure would be nice to have those settings on the GUI bit like the camstab and servo ones have migrated Would it be possible to use the MWOSD-GUI to calibrate ( more like an aftermath-routine ) the MSP-data? Also nice would be an "auto-zero" button in the GUI ( both GUIs) instead of a slid...

Hi all, this thread is a bit older, but fits perfect to my problem. I'm using MW2.3 and MWOSD. I'm reading battery voltage and amperes through the MSP-Serial port, because I don't want to fry my minimOSD board. I got it working somehow, but find it very annoying, I have to set the zero adjust and ga...

Sorry for all this OT... I got it working: The A2 port of the miniWii is the problem. It is designated as HV powerinput and messed up the current sensor signal. I had to redirect voltage measure to A0 and current to A1 ( on miniWii's config.h ). Finally I got a zero current readout of 2.5V instead o...

My sensor reads 1.58V at zero current, maybe it's faulty... I changed the AMPERAGEOFFSET to 450 ( was 158 ) and it doesn't change anything.. Actually I did the same zero offset stuff in MWii's config.h . I expect when minimOSD just polls data, it should read 0.0A. I've set the other amperagemax valu...

@ Olaf - which sensor? bi-directional can be a bit odd sometimes It's a ACS758B-050B from DFrobot. It has 40mV/A sensitivity and a zero current output of 1.58V I have a datasheet, but can't upload here ( .pdf) I really don't want to solder cables on the minimOSD atmega pins, otherwise I'd test it t...

I'm trying to read amperes from the multiwii-fc. In Mwii-conf I can't see an amp-value but the powermeter value. It increases by 1 (mAh?) each second, no matter how low or high I set the "psensornull" value. The amp-value from the OSD is always 5.5A and is also unchanged by the "psens...

shikra, the arduino nano has a 328p processor. IIRC,it has 2 serial ports. I also have an outdated i2c_to_serial GPS board, but I'm not sure if that works with GPS/mag combos?

@matster
you probably missed the different baud rate for GPS in the NAV SW? In NAV SW every serialport is set to 115200, reduce it to 57600 ( or what has been set in the 2.3 SW ) and try again.

<edit> Don't forget to erase eeprom between flashing a different MWII SW. ( all 4096 Bytes )

Hi O_Lampe, If you have Crius AIOP V2 as I have it is very easy to disconnect onboard Mag by cutting just two jumpers & use external Mag plugged into 12C port. This was the best mod I have done so far as Mag was totally useless despite twisting wires to ESCs & moving FC higher above distrib...

Hi, brewski already answered most of it. Fence radius should be higher than safe WP distance. ( At least it should be "safe WP distance + 2*WP radius" ) If you see the copter is hovering around a waypoint before it moves further to the next WP, you should increase WP radius to 300cm. If yo...

o_lampe

My best educated guess is that some servos can't handle the signal without prescaler.
If I understood correctly, the prescaler makes the timer count slower, which might have an influence on the loop time. ( e.g. prescale = 16 => refresh servo every 8th loop. )

I’ve been using 2.2 satisfactorily with Hobby King MultiWii Pro and am now trying b7.

I think we have to spend some time and finally make a documentation.

Any reason you don't trust ppm sum?

It's not the ppm-sum, I don't trust. It's just the luxury of 3 antennas pointing in different directions, I like.
That's why, I'm using the standard RX and a double antenna ppm-sum RX.

o_lampe

I've made a different experience with GPShold and stick-wrestling:
I can fly around with GPShold still enabled and when I release the sticks, the copter moves back to the place, where I enabled GPShold.
Probably it is because of some different settings in config.h ?

Actually the board/IMU itself should be able to recognize oscillations and react accordingly. Autotuning should be a matter of seconds for all PIDs. The fastest way to get a value tuned, is to start at 50% => Overshoot? Yes: goto 25%/ No: goto 75%...a.s.o Every Iteration cuts the remaining "val...

Since the mWII-NAV-version appeared, we are forced to use the Mega-boards anyways. With plenty of space for additional code for fuzzy-logic a.s.o.
But I also like the idea of a GUI-routine to preset the PIDs to a desired copter behaviour ( smooth, middle, and twitchy )

You are right, when your code set the values to zero.

Wouldn't it be better to start with PIDs preset to values known to be working and start autotune from there?
Or start with 50% value?

OT-question: Do you have public access to GPS satellites in egypt?

o_lampe

IIRC, you can set 250+ WPs in the mission planner. Taking into account, that each WP has to have a minimum distance to the others, you would need a very huge battery ( long flight time ) to hit the limit of megas internal EEprom.
Why would EOSBandi bother to write a code for a specific FC?
