the digital tube. The correspondence depends on the order in which you send the data when you wire and write the code. DS is a serial input pin, so-called serial is to make the data on a signal line in order to transmit one by one, like a string of candied fruit. This pin we received from the Raspberry Pi at any one of the Gpio ports (output mode). The SHCP is the clock pin for the shift regist

The raspberry pi system installs Linux and raspberrypi on the SD card. I just got a raspberry pi borrowed by Simon and prepared a 4 GB SD card for Linux. On Windows 7, use the tool Win32DiskImager to write img to the SD card. An error is returned and an error is returned. Fortunately, I have a Linux vmwarevm. Run the

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: 0 shutdown, shut down 1 single user,

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

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
