-linaro-arm-linux-gnueabihf-raspbian-x64 are used for 64-bit machines. Each cross-compilation tool has a bin directory in the directory to enter, execute./arm-linux-gnueabihf-gcc-v to view the GCC version. I use ARM-RPI-4.9.3-LINUX-GNUEABIHF here because the GCC version on the board is now 4.9.3 3. Start compiling 3.1 Enter the Linux kernel directory: $ CD ~/RASPBERRY/LINUX-RPI-4.4.Y $ kernel=kernel7 $ make

-lPS1080.soWith this file, pkg-config you can output the compiler, the parameters required by the linker, and the version information of the installed package. Check if it can be found correctly:$ pkg-config --modversion libopenni2If the version number is 2.2.0.0 , no problem.3. TestingNext, test whether the installation was successful. First, install CORE_SAMPLES , add in the Makefile last line:core_samples: $(CORE_SAMPLES)Compile:PLATFORM=Arm make c

you do not understand the operation of 2, want to look at the detailed steps here, in another blog:3. After connecting the Raspberry Pi to the WiFi, the installation method has a tutorial. It should be noted that if the WiFi signal is above 10 channels, it is likely not recognized, then the router's channel to tune not more than 10.4. To install the Remote Deskt

Today when I tried to connect the Raspberry Pi with SSH, I found that the Raspberry Pi did not open the SSH service.I don't have a monitor, I don't have an external keyboard.So, I pulled the Raspberry Pi hard drive (memory card) a

Your Linux distribution may already contain the Remote Desktop Viewer program, which you can use to connect your Raspberry Pi with VNC. This program can usually be found under the Applications/internet menu (the following is an example of Ubuntu);Once you select the Remote Desktop Viewer program and click the Connect button, you will see the following dialog box. Select VNC in the Protocol (Protocol) option

Raspberry Pi advanced GPIO library, wiringpi2 for python using notes (4) practice DHT11 decoding, gpiodht11 DHT11 is a temperature and humidity sensor with calibrated digital signal output. Precision humidity +-5% RH, temperature +-2 ℃, range humidity 20-90% RH, temperature 0 ~ 50 deg C. The encapsulated modules I bought contain the pull-up resistor. After che

;;EsacExit0The /etc/init.d/myscript is not yet randomly activated. Linux on boot, the real check is the/ETC/RCN.D folder, execute the script therein. The n here represents the RunLevel. For example, at run Level 2 o'clock, Linux checks the/ETC/RC2.D folder and executes its scripts. UNIX systems can work in different operating modes, such as single-user mode, multiuser mode, and each mode is called a runlevel. Most UNIX systems follow:Operating level:

the mobile power, from the mobile power of the USB is micro-port, Can not connect, need a male-to-male USB cable, there is no way to buy a data cable alone, the module is connected to the same way as other modules, connect the power of the USB port, the above pin has 3.3V, 5V, GND, it is clear, said above, the general module requires VCC and GND, Gpio above these two quantities are limited, you can receive this independent power supply module, out pin normal to the

downside is that no matter how big your card is, its partitioning depends on the operating system, which wastes some space. The command is as follows: DD if=raspybin bs=1kb count=4000 of=/dev/sdxx here xx is your SD card, don't make a mistake! Otherwise lose hard drive data at your own risk. I purchased a 8G SD card, after installing the raspybin image of Pi, insert the SD card slot, connect the mouse, keyboard and HDMI to power up. The firs
