Quadcopter - Raspberry Pi - Arduino - Esp8266 and more

I wanted to use RPIO library to drive motors I did however some tests of the python library RPIO. I was confident ... In fact, I have a 2.0 beta version unknown (I don't remember whre i find it...) and it does not work well. Unable to address certain pins, the output is not in OUT .... In short it is a real problem. As a reminder, this library is essential to drive the motors. It allows to make PWM control in hardware without soliciting the cpu. PS: After a lot of search on Google last night, it seems that the RPIO library is not compatible with all the models of Raspberry. In any case, it does not work on my Raspberry Pi 2. I will test other libraries like ServoBlaster or PigPio PPS: Another solution, less headache, buy an add-on card that manages the PWM in hardware. For example, this  Adafruit 16-Channel  PWM

Building a Quadcopter using Raspberry Pi... The idea came to me during my holidays by reading an article by Andy Baker in the MagPI newspaper (numbers 19 and 20) On reading the article, a quadcopter appeared to me very simple to build. And then, according to my research, I realized nevertheless that there are a lot of knowledge to know and that it will be quite complicated .. . So I bought the material on ebay: The F450 frame The 4 motors The 4 propellers The 4 ESCs The LIPO 3S battery The MPU6050 (gyroscope / accelerometer sensor) F450 kit The MPU6050 (gyroscope / accelerometer sensor) For the flight controller part, I use a Raspberry Pi 2 that I already have. As passionate computer scientist, the idea is to program the Raspberry to drive the engines according to the MPU6050 sensor which will provide me informations on tilt and acceleration. So, I will not want to use the CC3D flight controller provided in the kit. For the remote control, ...
