Past and future generations of SOA BPEL ESB I am not selling middleware, so I do not have to advocate the concept and principle of SOA.I am not preparing to write an SOA book, so I don't have to chew on it when I write my blog. This article involves

SPI interface SPI interface IntroductionSPI is a synchronous serial transmission specification released by Motorola. It is often used as a serial expansion interface for MCU peripheral chip. SPI has four pins: SS (from device Selection Line), SDO

SPI, is the abbreviation of English serial Peripheral interface, as the name implies is the serial peripheral device interface. SPI, is a high-speed, full-duplex, synchronous communication bus, and on the chip's pin only occupies four lines, saving

I still remember that the first time I used the SPI device was my junior summer vacation. At that time, I bought a wireless module with my teammates and used a single-chip microcomputer for wireless transmission, but the code was not written by

    I found some materials on the Internet to learn. It seems that I think the three Modelsim simulation methods are good, and I did it step by step. The results can be imagined. The problem is one by one, after two days of exploration, I

SOA is toxic That day in the QQ group, and a lot of internet users to discuss the topic of SOA, found that the industry's advocacy of SOA, not too much aircraft, said is the concept of high level, is too much, is talking about how to develop SOA.
