Ubuntu Raspberry Pi 2b cross compiling environment, ubuntu2b Generate executable code on another platform. Why is cross-compilation costly? One sentence: The last thing is. Sometimes it is because the target platform does not allow or cannot install the required compiler, and some features of the compiler are required. Sometimes it is because the resources on the target platform are poor, it is impossible t

Beginner Python , try to change the program that was previously written in C on the Raspberry Pi. Python version of the.

Raspberry PI Series--bare metal illuminated LED lightsBackgroundRecently just bought Raspberry PI B +, configured to run the official Raspbian system, tossing a week Linux system, feel no meaning, so try to understand the bottom of the start process, through a few days of research, It is found that the boot of the lowe

Tags: Raspberry Pi wiringpi Zookeeper 1. Void pinmode (INT pin, int mode ); This function sets the Input and Output Modes of the pin and the input and output modes of PWM. InWiringpi onlyPin 1 (bcm_gpio 18) supports PWM output. 2. Void digitalwrite (INT pin, int value ); This function is used to set the level of the pin. When we write high or low (1 or 0), the mode of the pin must be the output mode.

The first thing to note is that the Raspberry Pi Debian system is automatically scanning the display, in most cases cannot be displayed in full screen, that is, the actual display of the desktop is larger than the display resulting in some windows can not be displayed or closed, Either the actual displayed effect is less than the size of the display, resulting in black border areas around it. If this is the

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 checking the

package for the release. It generates a file with a name similar to "package-version.tar.gz" in the current directory. Package and version are the Am_init_automake (package, version) that we define in configure.in;>>make Distcheck: Generate and test the release package to determine the correctness of the release package. This action will automatically unpack the package file, then execute the Configure command, and do make to confirm that the compilation does not appear error, and finally promp

Prepare the hard driveAccording to the online introduction that if it is FAT or NTFS format may appear permissions problems, and then simply formatted as EXT4 format.Working with the Minitool Partition WizardWith a small USB flash drive, you can format the Raspberry Pi directly, the command is:mkfs-t EXT4/DEV/SDB1Installing SambaSet the shared folder to/samba$ Mkdir/sambaSet access Permissions$ chmod 777/sa

Automatic Logon 2. automatically run the startx startup Window System 3. After the window system is started, it automatically runs the custom program (generally the main interface of the application)
