!Initrd vs. initramfs Using initrd, kernel and initial file system are splitted. Making changes to kernel or filesystem doesn't touch the other one. The download size (e.g. while development) of one component is smaller. Creating and modifying an initramfs is easier than with initrd (unzip mount unmount zip) Having one big image (kernel initramfs) is easier to handle (e.g. download or flashing) than having two splitted images.

chip outside the microcontroller for level conversion, you can directly connect to the computer's serial port (COM ). The hardware structure 1 of the controller is shown in. the control circuit of the GUI interface is the focus of the hardware design of the controller. It should be pointed out that the use of intelligent GUI interface chip can greatly simplify the design of the GUI circuit. Currently, there are two most common types of chips. One is

But we can see there are two interesting chips on it: ST Microelectronics's microcontroller based 32f103 ARM cortex-m, BCM5976 touch screen controller, also found this part on the IPhone 5s and IPad Air. The reason why the 2015 13-inch Retina MacBook Pro battery lasted one hour was not only due to lower CPU power, but also subt

coefficient is reduced by one. The Fractional Divider automatically extracts each digit to adjust the Division coefficient. The calculation method is as follows: you can calculate the number of fractional part 1 first, and then place 1 evenly in the 8-bit uxmctl. This computation is relatively simple, the fractional part of the Division coefficient is multiplied by 8 to obtain the number of digits. The uxmctl value is displayed in the table. In addition, the error rate of each digit is calculat

the screen glass of Surface Pro 2 is integrated with the LCD, which means that the screen glass and LCD will need to be replaced if the screen is damaged. In addition, while the SSD in surface Pro 2 is replaceable, ifixit says the ifixit does not recommend that users do their own disassembly by simply accidentally breaking the dense wire inside the fuselage during disassembly. However, time-consuming and laborious disassembly is not meaningless, at least to give a clearer understanding of the i

Texas Instrument (Ti) announced the launch of its new simplelink Wi-Fi for Iot applications? Cc3100 and cc3200 platforms. Among TI's many new, simple, and low-power simplelink wireless connection solutions for Iot applications, the simplelink Wi-Fi series is the first in the market. Chip Description: Start your design with the industry's first single-chip microcontroller unit (MCU) with built-in Wi-Fi conne

New microcontroller types from all over the world emerge one after another. Most of these development boards use Arduino-improved versions, such as y ún, Which is improved by Arduino, it mainly improves or upgrades other wireless functions for the mesh network. However, some development boards have their own unique designs and basic function upgrades. Here we will take a look at these new partners that have been produced or are about to be put into t

Alljoyn was initially created by Qualcomm. The Iot-based open-source operating system is supported by the following most outstanding Iot companies. They are members of the allseen alliance, including Linux Foundation, Microsoft, LG, Qualcomm, sharp, Panasonic, Cisco, Symantec, etc. It includes a framework and a set of services, allowing the manufacturer to create compatible devices. It is cross-platform and its application interfaces can be used for Android, IOS, Mac OS X, Linux, and win7. 22.

Inner Connection-INNER join The INNER JOIN creates a new result table based on the join predicate combining the column values of the two tables (table1 and table2). The query compares each row in table1 with each row in table2 to find matching pairs for all rows that satisfy the join predicate. When the join predicate is satisfied, the column values for each matching pair of rows A and B are merged into one result row. INNER JOIN is the most common type of connection and is the default connectio

the MSP430 contains the adc12 module, which can complete 12-bit analog-to-digital conversion. When the requirements for precision or other indicators are not high, you can use the adc12 In the 430 microcontroller to complete the analog-to-digital conversion. Here we mainly implement a general adc12 module initialization Program . The specific data storage and processing needs to be added in the interrupt processing function. Hardware introduct

, the stability of the hardware problem is basically only to find a master redesign, if the circuit principle of the problem can also be directly increased or reduced components to solve. Software instability problems can be solved by modifying the program design and re-downloading the application to the chip. If from the design point of view, the system design is more important, because the system design requirements to understand some of the basic design of software, but also to the hardware d
