These values should be defined only once and the right place is in MultiWii.h.

itain

@schugabe, are you comparing to SVN version r1591?
Ales changed the range from [0;1000] to [0;999] in order to fix the reported array out of bounds access. I'm following the same line by using a [0;2559] range.

The prog_* types are not accepted by new versions of avr-gcc. The problem was reported by NikTheGreek here for Ubuntu 13.04. I see the same errors with Fedora 19. changing [GPS.cpp, line 240] resolves the compile error. void SerialGpsPrint(const char PROGMEM * str) { ********************************...

a. Note that there is a redundant definition of MINCHECK and MAXCHECK: MultiWii.cpp:#define MINCHECK 1100 MultiWii.cpp:#define MAXCHECK 1900 MultiWii.h:#define MINCHECK 1100 MultiWii.h:#define MAXCHECK 1900 b. Those integer divisions by 100 are very inefficient. Please consider: tmp = constrain(rcDa...

Change (GPS.cpp line 244) to: void SerialGpsPrint(PROGMEM const char *str) { I hope to see that changed also in the SVN repository. The same problem exists also in Fedora 19 and probably in all the major Linux distributions. The type ` prog_char ' is defunct. Your Ubuntu installation is probably usi...

3) all those static functions ... why are they static? AFAIK that confines a C-function to be only available in the file it is defined in. Declaring a function static doesn't seem to make a difference in the produced binary There may be two reasons: a. Optimization... Using static functions may hel...

1. It's a binary protocol, and you need to send the checksum as well. From your question it looks like you are sending ASCII without checksum.

2. The two can run together... You can use the serial protocol while flying (eg, for an OSD).

Look at https://code.google.com/p/rush-osd-development/source/browse/KV_Team_OSD/KV_Team_OSD.ino . The function calculateTrip is called every 50 ms and it is estimating the distance traveled from the GPS_Speed. Having the total travel distance calculated by the GPS code could provide more accurate r...

Hi folks, as fpv regulations are still to evolve, i think we shoud put an identification field on the OSD, like cars have. There was a suggestion to add an optional "personal logo" in the form of two adjacent characters (total 24x18 pixels). Each pixel can be white, black or transparent. ...

Thanks Alex. MSP_BOXIDS is working good as expected. I tested it in flight today today with r1333.

What we can do : add a new array of uint16_t (more than 65k possibilities, or uint8_t maybe it’s enough) is order to uniquely identify a function over the time. The index id would still be variable, but the function comparison should be much easier. This new array could be grasp via MSP_BOXIDS. Is ...

Subject: add MSP_BOXIDS . Each box would have a unique id, that should be stable across future versions of MultiWii. The reply to MSP_BOXIDS would be a list of these ids.

kataventos, Question: do you have a tool for debugging the code or do you flash the firmware, then connect the OSD to a MWC FC? I hope you have a program that you are running on the host computer that simulate the FC. There is no usable simulator yet. A simulator would be very handy for testing and...

Are you using Rushduino? Which version? I will refer to recent development versions (see m) that has not been published yet. Other versions may have known bugs.

Thanks for reporting. I already fixed that in my code and will push to the repository later today.

In the mean time, here's a recording from last Friday. New updates to the OSD firmware are on the way. Pilot (non FPV) is Barel Atanelov.

I see that development has slowed down.
Dev_r1240 is there for almost two months and it appears quite stable and with many new features that are not in the official 2.1.
If my vote counts, I would say yes for a new official release that's based on dev_r1240.

Dave, your Crius SE is 8 bit and you are asking on the 32 bit section.
Also, I do not understand how you can have AUX channel if you have only 4 ch receiver.

Thanks kataventos, I tried the latest 2.0 with same results. I suspect the problem may be over usage of ram (and stack overflow).

Hi, I suggest to change size checks in Serial.ino. Use >= and not ==. The protocol has changed several times and in all cases only new fields are added.

The spin-up time after power up is probably because the outputs are still in 3-rd state until the arduino leaves the bootloader and lets MultiWii initialize the I/O.

ok, so we got two open cases that need investigation: - spektrum sattelite - ppm As I have neither, anyone care to test and report? I'd be willing to apply the code change on that basis.

Danal, thanks for the info. I think the Paparazzi Spektrum support was mostly written for DSM2 (when DXMX was not available or at least not widely used).

I have just created a new branch that's using C++ files. Trying to migrate from arduino to C required too many changes to do in one step.

Why isn't OO style good Alex? just curious. OOP is actually very good if there are enough computing resources. MultiWii would mostly run on systems that don't have such resources.

Thanks Alex. Lets see... GPS.ino is now the only place that's using a C++ class. Translating it to pure C is not a big effort. Is that EOSBandi's code?

Optimized code should not care. Decent compilers can split the scope of a variable to "live range" that usually start on assignment to the variable and end in the last use before the next assignment. See more here: Live variable analysis.

The only issues are portability and readability.

itain

That's because it's C++ code - why not use the proper extension .cpp for that? Thanks Tommie. I already considered it. If you have seen the latest commit the GPS code must compile as C++, so not I have a mix of C and C++. I may switch the other files to .cpp and forget about these issues. My bigger...

The V22 is only one example of what could be done... The idea is to be able to smoothly switch between two (or more) different configurations while in stable flight mode.
