MultiWii

Sure:) code is still dirty: many blocks are not commented out. Here some photos This is OSD without camera connected http://s017.radikal.ru/i405/1309/7a/fc54858bbee6.jpg This photo shows OpenRTOS Tasks used http://s020.radikal.ru/i723/1309/e4/53ba271cec78.jpg Open Air fly m

Hard work is done. New Firmware (based on MultiWii 2.2) rewritten to work with OpenRTOS. New Config to MPU-6050 -> Sensors are update at 100Hz. Added second board with OSD on MAX7456. Added driver for OS to work with it. The OSD code based on RushDuino. Photo will be soon (i just crashed my copter a...

Is it possible to lock copter position using accelerometer and gyro ?

Since i use MPU5060 with prescaler equal 15 (8000/15) = 500 Hz -> 2ms for one measurement for GYRO+ACC. In this case part of main loop() called every 2ms (+/- 100 us) that consist of filter for ACC and GYRO. To get one MAG measurement need to spend 6ms and next part of loop() code, that calc angle[R...

about 2kb RAM for RTOS (sheduler) + about 200 bytes RAM on every running thread ( stack ). If you mean FLASH resources, compilled project about 56kb. My project is so big size cause USB CDC Com Port emulation due to use MultiWii GUI.

No. At this stage it's only an idea because i use PICmicro device, not Atmel.

What anybody think about subj? Main cycle will be fixed time delay ( read sensors, filter it and apply PID), with max priority. Other threads like buzzer, OSD, Led,Sonar, Baro and UART with low priority. CPU time will most balanced. I have adopted sources for PIC32MX795F512H ( 80MHz ~80MIPS). Now in...

I can send it by email. But i haven't idea how to share it. I't not one or two files. Changes was made across many multiwii files. Were added some new "drivers" to communicate with SPI sensors and russian GPS\GLONASS receiver.

I cannot go out to make experiment on openair. Still haven't battery.. Now copter is powered by computer power source ( 12V 32A) and have voltage drop on half throttle about 10.1V. If i'd like to set full throttle - voltage drops over 9.5 V

Hello. Here my construction of quadcopter. Frame - DJI F450. Board - handmade) MCU: pic32MX with 80MHz, 128 kb SRAM, 512 kb Flash Cycle time is about 1650 uS Board consists: Acc\Gyro: MPU6050 (I2C) MAG: HMC5983 (SPI) BARO: MS5611-01BA03 (SPI) GPS: NV08C-CSM (RS232) EEPROM: 8kb (I2C) Also, have added...

HI! The Mag will help to maintain your yaw direction and is necessary for gps functions, so the copter knows its heading. For sensor directions have a look at m greetz Noc Thank you very MUCH) This is what i need!) I have another question) May be you're know answer. Accelerometer\Gyro\Mag have digi...

I have found soluton! ) MultiWii have successfully ported to PIC32MX platform. But some questions are present.

1. What function of MAG in copter?
2. What orientation of MAG sensor is right ?

Hello) I have new board with MPU6050 Acc/Gyro + HMC5983(SPI) + MS5611-01BA03 (SPI) . MultiWii was changed to use the SPI sensors. So, i have some trouble to recognize right orientation ( ACC_ORIENTATION, GYRO_ORIENTATION, MAG_ORIENTATION defines). All Sensors on boars have right orientation ( by PDF...
