require a Port Pin to implement some timer functions. Some processors also have drain output and high current output capabilities, you can easily directly drive relays or solenoid coils without the support of additional drive hardware. When counting the processor I/O pins, we must take into account some pins that are used in a time-limited manner using the processor's internal functions (such as serial interfaces and timers. 1. 2. Number of interfaces to be usedThe main function of the embedded

Widgeduino-unveiled on Kickstarter recently-is a smart and easy-to-configure window-based on Microsoft Windows platform and Microcontroller System Communication applications based on Atmel-based Arduino board. Essentially, widgeduino communicates with the Microcontroller System through the serial port protocol or TCP/IP. "This includes, among others, keyboard, LED light, pressure gauge, knob, Slider, thermometer, container and button. the intuitive m

). After the DC is balanced, differential signal transmission is better in electromagnetic compatibility than LVDS and TTL. The connection and Transmission Structure of long-distance and high-quality digital signal transmission tmds technology can be achieved using low-cost dedicated cables. 1 is shown in DVI digital signal transmission uses single link and dual link to transmit data only through channels 1, 2, and 3 shown in Figure 1, the transmission rate can reach 4.9 Gbps, while the dual co

, the data interface subclass requires a periodic (isochronous) terminal point whose direction is input (in) and a periodic terminal point whose direction is output (out. The control terminal points are mainly used for enumeration of USB devices and communication between the baud rate and data type (Data bit, stop bit, and start bit) of virtual serial ports. The non-synchronous terminal point in the output direction is used for the host to send data to the slave device (slave), which is equivale

TinyOS is a free and open source, component-based (component-based) operating system and platform for wireless sensor networks (WSN, wireless sensor network). TinyOS is an embedded operating system written using the NESC program as a result of a series of collaborative projects. Its first appearance was as a masterpiece of UC Berkeley and Intel Research collaborating labs, embedded in the smart micro-dust, and then slowly evolved into an international cooperative project, the TinyOS Alliance.The

, which requires not only the external hardware to have real-time processing capabilities for interfaces, in addition, the processor must efficiently process interface data at a sufficient speed. For example, at91rm9200 is an industrial arm9microprocessor produced by ATMEL. It is based on the ARM920T core and can process up to 200 MIPS, at the same time, the processor is configured with USB, Ethernet, infrared serial port supporting RS485, IIC, SPI, S

How to disable the Asus S550C touch screen in ubuntu I accidentally made a crack on the Asus S550C touch screen, which caused the screen to automatically click, seriously affecting the use. In windows, the touch screen can be directly disabled through the FN + F7 shortcut, but after the ubuntu system is changed, the shortcut key is no longer needed. After a while, I finally found a way to disable the touch screen through xinput. The specific steps are as follows: 1. Enter xinput on the termina

both design and manufacturing capabilities, and some companies only have one of them. In addition, design and manufacturing are inseparable because of technological issues. Even companies with only design capabilities must consider the production process of a third party when entrusting a third party for manufacturing; in turn, companies that only have the manufacturing capability must consider whether their manufacturing processes can meet the design requirements if they provide production ser
