data (u0thr, u0rbr );Check the serial port status or wait for the serial port to be interrupted (u0lsr ). 21. Basic I2C operationsAnswer: The basic operation method of the I2C host is as follows:Set I2C pin connection;Set I2C clock rate (i2sclh, i2scll );Set as host, and send the start signal (i2en, Stas, and AA are 0

disk drives can work in parallel to improve the data transmission rate; thirdly, the verification technology improves the reliability: if one hard disk in the array is damaged, the original data on the damaged disk can be restored using other disks without affecting the normal operation of the system, the damaged hard disk (that is, the hot swapping function) can be replaced in the live state. The array controller automatically writes the restructured data to the new disk, or write a hot backup

Interrupt. Otherwise, the External Interrupt can only be reflected in the extint register;To enable the device to enter the power-down mode and wake up through external interruptions, the software should correctly set the pin's external interrupt function before entering the power-down mode. 20.

The first difference is of course the name:SPI (serial peripheral interface: serial peripheral interface );I2C (Inter IC Bus)UART (Universal Asynchronous Receiver Transmitter: Universal asynchronous transceiver)Second, the difference lies in the electrical signal line:The SPI bus consists of three signal lines: sclk, SDO, and SDI ). The SPI bus allows multiple SPI devices to connect to each other. The SPI device that provides the SPI serial clock is t

MSM8909 + Android5.1.1 keyboard driver --- sn7326 Introduction 1. Sn7326 Overview SN7326 is a keyboard extension chip with intelligent self-scanning, supporting up to 8x8 buttons. The press/release button action is encoded into a byte of data and stored in the key event register. The master controller can read the key event register through the I2C serial bus. SN7326 has the dejitter function. When any key is pressed, the interrupt output pin is set t

[Tutorial] Linux I2C device driver-Linux general technology-Linux programming and kernel information. The following is a detailed description. My ARM platform is Cortex A9. The MSP430 microcontroller communicates with the ARM-core I2C bus. the ARM runs on a Linux system and the Linux kernel has an I2C bus driver. Therefore, in addition to the MSP430 program, I a

In the Linux drive, the following members are mainly included in the I²C system:I2C adapter 即I2C适配器I2C driver 某个I2C设备的设备驱动，可以以driver理解。I2C client 某个I2C设备的设备声明，可以以device理解。I²C Adapteris a CPU integrated or external I²C adapter, used to control a variety of i²c slave devices,

Two-wire serial bus developed by PhilipsGPIO analog I²c driver has its own set of transmission algorithms. Gpio analog i²c is to consume CPU resources, and the use of the I²C chip is not the CPU resources featuresFewer interface lines, simple control mode, small package form, high communication rate features a serial data line SDA, a serial clock line SCL It is a true multi-host bus, and if two or more hosts are initialized at the same time, data transmission can be prevented by conflict detecti

platform quickly judges the execution logic, performs synchronous operation and analysis, and gives the quality diagnostic report of the tested application while the user manually clicks on the application to be tested. For example, the test process of critical module leakage analysis, testing adequacy measurement, code static quality analysis and the collapse of the white box-level capture and analysis. If you have questions about the test results, you can use the client's code coverage visual

on the application to be tested. For example, the test process of critical module leakage analysis, testing adequacy measurement, code static quality analysis and the collapse of the white box-level capture and analysis. If you have questions about the test results, you can use the client's code coverage visualization to directly validate the results. In addition, all the data from the Nebula test can be traversed in the version, and all data analysis results specifically consider the aggregati

The company bought an oscilloscope a few days ago, and the process was like this: 1. The development department bought an oscilloscope and found a proxy for XX Company in Guangdong on the Internet. 2. So I called:Engineer a said: How much is XX oscilloscope? Sales lady B said: "XXX price" Engineer a said: We are going to buy a batch. Can we get a discount. Sales
