MultiWii

I tried to use Visual Studio 2010 with VisualMicro, but I always get the following compiler error, if I uncomment "#define SERIAL_SUM_PPM" in config.h. Does anyone has the same problems or a solution??? Why do you all prefer Eclipse instead of Visual Studio (Express)? I think Visual Studio...

mahowik - there's a bug in the baseflight implementation of frsky tele and yours - you need to do xor-stuffing when the output sequence has 0x5e in it - check the pDF and er9x implementation for example. Ive been meaning to fix this in my code, not often occuring condition but still needs to be tak...

Regarding the ER9X code..... the custom screen is nice.... just a shame in the current version it is not stored in eprom... Yes, this is a problem of er9x, actually I switched to open9x because it stores the datas in eeprom and you have more possibilities with FrSky telemetry, for example telemetry...

- e.g. it doesn't make sense to send GPS_speed and Course every 500ms because frsky receiver will send it every 1 sec. No, YOU can decide how often the Datas will be send. Only if you use the FrSky sensor hub, the Datas will be send as defined in the source code of this hub. If you copy GPS speed f...

Thanks for testing the GPS part. I've changed the code in the post. I'm not expert in microcontrollers programming but actually as i see SerialWrite() also based on interrupt... So what is the advantage of your implementation? Because you have "separate" interrupt only for serial port 3? I...

So i have found out that cycleTime increases for 2-3ms when you are sending packets about 8-16 bytes, so I have success with transferring of GPS lon/lat/speed/alt, Baro ALT by using SerialWrite() function from mwii_2.1 code... BUT in case of trying to send all data which are supported in FrSky HUB ...

I've integrated telemetry today and it seems to work (MultiWii 2.1). I've a Atmega2560 (Flyduino MEGA) so I can use serial Port 3 and don't need a soft RS232. I work with interrupts, so the totale cycle time increased only about 2 ms. To invert the TX-signal I used a single Schmitt-trigger Inverter ...

I don't have much experience with the MultiWii code. But I think, there will be a Problem with the cycle time in both codes in this thread, if we send about 100 byte with 9600 baud, isnt' it?

Hello, I'm looking for a description of all the GUI parameter. The chapter "Configuration via GUI" on the homepage is for MultiWii 1.7. Can I anywhere find a description of all the other PID Values like "ALT", "VEL", "GPS", "LEVEL" and "MAG"...
