Before discussing buses, we should first understand what a bus is. According to Baidu, the complete definition is: a bus is a common communication trunk for transmitting information between various functional components of a computer. It is a transmission line bundle composed of wires, categorized according to the type of information transmitted by the computer. … Read more
UART, SPI, I2C and other serial communications are very common methods in embedded development. The underlying communication principles are not difficult, but many beginners struggle to learn them.
