thanks for confirming.
I wished for people to read the wiki instructions now and then - at least when they experience problems with stuff that has been around for a long time.
Different configuration instructions for (v2.3 or newer) and (v2.2 or older)

Hamburger

analog.intPowerMeterSum is where computed mAh get stored. From memory without code.
What do you use to see this value?
I use it all the time together with capacity warning on serial display and it just works as expected.
Dunno for the gui though.

Hamburger

when using pc application is that over bt too?
else board might get its power over usb serial with different voltage. this could lead to different sensor values. personally I have not seen such rx value shifts though.

Hamburger

it is likely your rx does this as its failsafe routine. Some rx can be configured to send some predefined value (usually what was used during binding) in case of failsafe. In that case make sure to trim your tx during the bind so it sends an out of bounds value (<980 or >2050) on one of the first 4 ...

Hamburger

Just back from the field, I can confirm it works.

Hamburger

No danger. With original nunchuk sensor it was above 6000 always. But if cycle time varies very much then it will have influence of flight characteristics because pid algorithm is not time invariant. In effect you tune for one value of cycletime. For a completely different values those pids will hav...

Hamburger

Cool.
So MWii does the right thing and I am all set.
Thanks for the clarification

do you change this via ucenter or the initialization code from inside MWii?
(I have just changed to 57600 via ucenter to avoid serial glitches)
Is 5Hz default?

thanks for the help/

Hamburger

from what I understand those gps modules support a range of protocols. Accidentally, mine came preconfigured for NMEA. To change serial speed from 115200 to 57600 I went and installed ucenter on a win-pc. So I am all set to configure the module. Now i am wondering whether switching to another protoc...

parital fix to Protocol..cpp in r1737 It will kill the Promini FC and GPS as a option.. why so? my partial fix only prevents handling of "other serial commands" but not of the MSP commands on the gps.serial port. True, I am still not convinced having both MSP and GPS on same port is guara...

parital fix to Protocol..cpp in r1737

Bug : an attached (nmea) gps can induce data chars which may get interpreted either as MSP commands or via evaluateOtherData() as serial commands. Symptom : this may drop user into configuration.loop or trigger other functionality. What is even more critical/confusing: once the gps is physically at...

Hamburger

On my mega board with gyro, acc, baro, mag + lcd.telemetry, the loop time frequently exceeds the 2800 limit. I see value going up to 3200 every other second. The whole idea of enforced constant loop time gets ridiculed if the limit is too low. Can others please comment on their loop times? -- EDIT: ...

I found two bugs - attached (nmea) gps can induce data chars which may get interpreted via evaluateOtherData() as serial commands. Bug: this may drop user into configuration.loop or trigger other functionality. - Cannot be avoided with disabling gps in config.h. Reason: in v2.3+ even on gps port, in...

Hamburger

For the release notes:
which version of arduino and processing are used for the baseline?

Hamburger

To my knowledge, nothing beyond the file names

Hamburger

Of the two I.d prefer the second variant. But I have no grasp of possible side effects as my experience with gps and baro are limited. So it may have to wait until after 2.4 or other frequent users of such combos must chime in.

Hamburger

Afaik we do not support using gps info for altitude.
If you require altitude then baro m7st be activated in config.h.
Sorry.

Hamburger

Alex, I think with your last change to gui you also reactivated the truncation of leading /dev etc. from serial device names? If true then it breaks the rwconnect feature for mac and * nix. I had had to disable this truncations long ago for that reason although it was nicer reading the list. Sorry I...

Hamburger

Carlo, But then you cannot land at other place (mountain) to deliver package (there disarm and arm) because on flight back the altitude will be corrupt= different from first direction. Not a good idea. If you have a Bt connection to your fc, then you can send a 'R' for resetting various values. This...

Hamburger

switch back for the moment version number to 230, but winGUI will have to handle 240 for final 2.4

I think it is wrong signal if we effectively cripple the version number only to please some (albeit honored) 3rd party app.
If they test for ==230 then it is either intended or plain wrong and bad.

Hamburger

Sure, if you say so.
I am sorry to have wasted time trying to help when you know for yourself where and what to look for.
Good luck

Hamburger

Nano.v3 board has 328 cpu.
Goto arduino pinout page to find pin-port relations.
For on/off functionality it is sufficient to use pins in digital mode (like buzzer)

Hamburger

Withou code my advice:
Look at BUZZER code.
Pins and ports are different for supported cpus.

Hamburger

Progress is very visible.
What are current weight, battery, flight time and speed please?

Hamburger

Disable the baro sensor might save enough? No alt.hold then.

Hamburger

Yes. In general applications/programs should consider being less restrictive on the version.
We increment the minor digit at will during development to indicate work in progress.
And most changes should not break existing functionality so users should be safe.

Hamburger

correct, current MWii does not support SPI.
correct, we are interested in optional SPI support.

If you want to pursue implementation of SPI support, please no 3rd party fat libraries.

Hamburger

You mentioned you have a "pro"board. I assume that means it has 2560 atmega chip. Then in MWii config.h, verify you have hardware pwm enabled and set the rate to nothing higher than what your servo can handle (best to keep a safety margin; you most likely will not notice the difference in ...

Hamburger

good analog is better than cheapo digital.
Metal gear is well worth it for TRI

Hamburger

IF you keep burning servos that could be based on either - servos are junk (some cheapo servos are just that); or - the attached mechanical load is too high; or - voltage is not correct; or - pwm rate is too high - this happens regularly when attaching servo (50Hz for analog servos up to 333Hz for d...

Hamburger

not exactly what you want, but you could use the buzzer feature to drive the buzzer output pin (of your choice) - use a transistor to drive your lights, - assign buzzer.on to an aux channel to switch on - accept to see various other signaling sequences flashing even while buzzer.on is set to off. It...

Hamburger

Additionally to PIDs etc, for all features which require a value and are marked with (*) in config.h, those values are definitely stored in each profile.

Hamburger

That all said it seems I don't have much choice but to limit myself to 6 servos I'll stick to something like the Chinook in the meantime. If you look here m you will find 2560 has >8 pwm-capable pins. You could free up some pins by attaching your rx via sbus/ppm/serial single wire instead of 8 for ...

Hamburger

dunno. The original implementor of DEBUGMSG seems to have left long ago. I have never used it - for me it is always either debug[] or an attached lcd/oled. If you want to follow that DEBUGMSG route further you could search for the implementation of that functionality and see if looking at it hard en...

Hamburger

got it. Noted, thank you

Hamburger

the DEBUGMSG stuff should output on the console. If you run the MWiiconfig from a terminal window that is where you should see the debug messages appear. Other ideas: if all you want to see is some values we have the debug[0]..[4] variables which also get displayed as nice graphs in the gui. Or you ...

Hamburger

Hi Rudolf,
I am especially interested in that error with POWERMETER_HARD. Can you please attach your (maybe zipped) config.h so I can understand how that could happen. It has not come up with my any of my test configurations, so it might become interesting.

Hamburger

afaik it requires sending a checksum byte which may be difficult to compute manually and difficult to enter in the terminal program?

Hamburger

experimental:
heli yaw precomp dependant on collective pitch
individual cells voltage monitoring (alarm portion undone yet)

Hamburger

I think we can continue to include binaries and images etc. in the repository section.
It is the dedicated downloads section which gets terminated. Bad enough.

Hamburger

you cannot use both; it is either sat on main RX
or
no main RX and sat to the board. Advantage: less pins used

Hamburger

to ease the workload best get a mega2560 board. Be prepared to dive into the code heavily (or use servos which will withstand the 490Hz pwm signals of ESC/motor outputs and reuse the octo coptertype).
