▲Click the card above to follow and learn more▲ Communication issues, like traffic problems, can vary in speed, congestion, and interruptions. If we compare serial communication to traffic, UART can be likened to a station, and a frame of data is akin to a car. Cars on the road must obey traffic rules. In the … Read more
SPI (Serial Peripheral Interface) SPI is a high-speed, full-duplex, synchronous, serial communication bus with a 3-4 wire interface, operating in a master-slave mode, allowing multiple SPI devices to be interconnected. The SPI device that provides the SPI serial clock is the SPI master, while other devices are the SPI slaves. The SPI bus consists of … Read more
Look at the image below; you probably guessed that today’s protagonist is UART. The serial port we commonly refer to includes both TTL level and RS-232 level, and in embedded systems, the serial port of microcontrollers is usually TTL level. Today’s content is about the frame format of UART, which is quite simple; those who … Read more
