Navigatron - I2C GPS for MultiWii and Others - FLYTRON. Arduino Nano ATmega168 - emartee.com. Nano 3.0 with Atmega168 Overview The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0) or ATmega168 (Arduino Nano 2.x).
It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. Schematic and Design. RCTimer/Turnigy/Hobbywing ESC DIY Firmware Flashing. Thanks to the help of timecop (yes he can be nice as long as he is interested ) I managed to flash my RCTimer 10A and 30A ESC.
The procedure should be the exact same for the 18A and 20A versions. I will have some of these ESC in a few days and will test. Only difference can be the programming pads order, we will get into that. Also note that the procedure is most likely the same for the Turnigy Plush if they have the same chip and pads. Another note. timecop and I also had some RCT 10A that went poof after the reflash. 1- Required stuff: - RCTimer or other Atmel chip compatible ESC stripped of it's shrink tube. Check this list made by TomSn0w of all compatible ESCs with their specs and appropriate firmware file. . - An AVR USB programmer.
. - The hex file for the firmware (.hex is the compiled firmware, you can compile your own if you want to as well): View topic - Inflight ACC-calibration. Multiwii V.2.0 Preversion. Software « MultiWii. Once downloaded in the Arduino board, the software set the default settings during the initial start.
These settings are appropriate for a configuration similar to mine (motors / ESCs / propellers / weight) However, another configuration will probably require other parameters to be optimal. For instance, if you want to use a larger multicopter for FPV. The multicopter uses a closed controlled loop to ensure its stability and manoeuvrability. Like most multirotors, it is a Proportional-Integral-Derivative (PID) regulator. This controller is translated into software code lines in the Arduino and tries to correct the error calculated between a measurement at the controller output (measured by the gyros) and an input set point (position of the stick), using appropriate action to adjust the output of the process (command to motors). PID controller involves three separate parameters: the term Proportional, the term Integral and the term Derivative. There are 2 ways to modify the values: Hexacopter Multiwii CamStab testing.

View topic - Alt. Hold Ideas and discussion#p8983. MultiWii is a general purpose software to control a multirotor RC model.
It can now use various sensors but was initially developed to support Nintendo Wii console gyroscopes and accelerometers. We can find these sensors in the extensions of the Nintendo WiiMote: Wii Motion Plus and Wii Nunchuk. This project was an opportunity to develop my own software on an Arduino platform. The achieved stability is excellent for FPV and allows any kind of acrobatics. The software is for the moment able to control a tricopter, a quadricopter or a hexacopter. The tricopter mentioned in this article is mainly is the first tricopter I made, based on a fiber structure. Wii Motion Plus A Wii game controller is composed of three accelerometers to determine an angular position, and measure lateral accelerations. There is extensive information on all the extensions here: On a multicopter, the use of accelerometers is a plus but not necessary if you do not want to keep strictly to its angular position in space.

Erstmalig im Sommer 2010 präsentiert, hat sich das Open Source Projekt um AlexinParis schnell weltweit verbreitet. Die Software wird ständig weiter entwickelt und eröffnet immer neue und interessante Möglichkeiten. Insbesondere Quadrocopter liegen augenblicklich sehr im Trend, doch nicht jeder kann oder will sich ein teures kommerzielles Produkt leisten. Die komplette Steuerelektronik eines MultiWiiCopters kostet dagegen kaum mehr als 50 Euro.
Am Beispiel eines Quadrocopters soll hier gezeigt werden, wie schnell und einfach sich eine wirklich brauchbare Flugsteuerung bauen und konfigurieren lässt. Eine MultiWii-Steuerung besteht im Wesentlichen aus einem Arduino 5V/16MHz und einem Nintendo Wii Motion Plus. Das Wii Motion Plus (kurz: WMP) ist ein dreiaxiales Kreiselsystem, das dem Arduino zur Fluglageregelung dient. IX: Weitere Quellen.
