Years ago, learning a bit of OPENCV, through the OPENCV can be simple to achieve the face of the follow. Plus a few servos to control the head rotation, the robot can interact. OhHere do not do video demonstration, just put out the code, interested friends can experiment with their own. The basic principl

system, our lives also revolve around an increasing number of ARM devices-from raspberry pie (raspberry Pi) to Chromebook and Nvidia Shield. Traditional distributions written for CPUs of the INTEL/AMD architecture are not capable of running on these ARM-architecture devices. Some of the distributions written for ARM can only be run on specific hardware, such as the Raspbian system, which can only run on the raspberry pie (raspberry Pi). That's why Ar

I'm using the raspberry Pie 1 B, which actually has a higher type of raspberry pie, but the principle of waste utilization The version I'm using is 2016-09-23-raspbian-jessie.zip The advantage of this version is that it can be connected to SSH for the first time, and subsequent versions will not work. The first power, to ping the later to wait a while to SSH, then extended file system, set the keyboard layout and other common tasks Start In

I built the project named CPU and set the base class to be qdialog. Implement pallet Display The first thing to do is hide the main window. The function of this program is through the tray icon, so the main window does not need to be displayed. Enter main.cpp and delete the following code: W.sh

Enable Raspberry Pi camera without Raspi-config ask: HiI have installed the latest Ubuntu Mate on my Raspberry Pi2. I wanted to use the Raspberry Pi camera in this operating system. Although I installed the ' Picamera ' driver in it, the system can not be create the camera component when I ran "Raspistill- o test.jpg ".Because there is no "raspi-config" in this OS, I has no idea to further set the camera. For the same camera and Pi, when I use a Raspbian
