Description

technical field

[0001] The invention relates to the technical field of bus communication, in particular to a bus terminal controller, a bus communication power supply system and a communication power supply method thereof. Background technique

[0002] Micro control unit MCU, also known as single-chip microcomputer or single-chip microcomputer, is to appropriately reduce the frequency and specifications of the central processing unit, and integrate peripheral interfaces such as memory, counter, USB, A / D conversion, UART, PLC, DMA, and even LCD. The drive circuits are integrated on a single chip to form a chip-level computer, which can be controlled in different combinations for different applications. At present, the MCU is mainly used for the control of mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepping motors, robotic arms and fire monitoring systems. The fire monitoring system generally includes fire emergency lighting and evacuat...
