Research of Automatic Digital Multimeter Interface Technology Based on UART

Because Automatic Digital Multimeter is huge and not compatible, automatic digital multimeter provide a serial communication interface to avoid the trouble of moving the instrument. This paper uses the method of serial communication based on UART, through the UART interface design, solving the problems of automatic digital multimeter serial communication. The results of the study show that using UART serial communication, users can quickly and efficiently measure the data of voltage, current online, etc. It is convenient and easy.
