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...
In order to accomplish the field bus and intelligence transformation for traditional vortex flow meter, we design a platform embedded µC/OS-III and develop a complete set of HART and RS485 communication interface on this platform. It can be easily composed with traditional vortex flow meter to achieve function of remote control and collection in the case of minor change to the originals. With this...
