MultiWii

I am trying to implement this on a HK Multiwii Pro board and a X8R receiver. I believe I have configured and uploaded the Multiwii 2.4 with S.Port correctly. I have built an inverter as descibed here m. My problem is that as soon as I connect the inverter the MWC freezes/crashes. I have found that ...

LutzB what value transistors did you use ??. I used PN2222A general purpose NPN switching.

I too am interested in how this is done ..

That was it ... supply the board with a 3.3 volt source and all is now working. No more corruption and I have been able to speed the serial up to 57600 with no issues..
Now off to break something else ..

OK ..Found one of the issues.. I am using a LC Studio card reader and they seem to be very touchy with input voltage. If a feed it 5 volts things are OK, but a 6 volts it is trouble. It looks like that the onboard 3.3 regulator is not very tolerant. Still can't go any faster than 9600, and from what...

Thanks Liriel .. I must have an issue as the only serial speed that works for me is 9600. If I try and speed it up to 57600 or 115200 by adjusting the serial speeds and recompiling, I get nothing but garbage on the card and have to reformat in a pc. Sometimes I get a log directory with nothing in it...

Newbee help please ... Could somebody please confirm that the connections from the flight controller to the pro mini would be a crossed over tx - rx serial connection. i.e. HK multiwii pro serial 1 tx/rx to pro mini rx/tx. I have managed to complie and load the sketch, but when I go to read the card...

Is it possible to pick up GPS time from the FC.
I have a MultiWii PRO Flight Controller w/MTK GPS Module and I am playing with Alexinparis pre 2.4 code and configuring the GPS with
MTK_BINARY16. Since the FC is retrieving that information could that not be passed to the OSD ??

I discovered that it "crashes" if you don't uncomment
#define USE_MSP_WP
It seems it cant run without it!..

That was it....Thanks so much...Now I can get back to testing

I changed the version in the multiwii.h to 230 - now it works. I tried this and I get the following.....Any ideas ?? ************** Exception Text ************** System.ArgumentOutOfRangeException: Value of '0' is not valid for 'Value'. 'Value' should be between 'Minimum' and 'Maximum'. Parameter n...

Thank you for your time. It is appreciated.. Using your pointers I have been able to achieve what I was after.
I can now display either utc or local time on the FrSky FLD-02 Telemetry Display Screen.

I am wishing to extract the time from the GPS nmea No, that is not foreseen in the current implementation of MW. However, it can be easily implemented by adding a line to gps.ino dealing with the time. But, for what purpose do you need the UTC time? In my view it is better to have the time of armin...

I am just getting into this C++ so please bare with me.
I am wishing to extract the time from the GPS nmea. In the current MW 2.3 is there a variable I can get a source from i.e. in GPS.cpp ??

Thanks for that ...
Once I figured out where to place the code, it does what I want.

Is it possible to extract trim values using debug ??. Client or terminal prog.??
When testing newer versions it would be nice to use them to tune instead of going through the trim process each time.

It is a good idea, plus perhaps you can change them from gui... it could be faster than changing trim with stick controls

Is it possible to extract the values using a terminal program like MultiWiiCL ?

Would it be possible to show trim values in the GUI ?
