An intelligent instrument based on controller area network (CAN)

This paper presents an intelligent instrument with strong versatility, efficiency, low cost and other advantages. The function of data-processing is described using the chip of STM32F103C6 as the master controller, and the function of data-transmission is described using the analogue to digital converter (ADC) and digital to analog converter (DAC) as the extension of system. An approach to designing the intelligent instrument based on CAN is presented. With the approach, it can finish communicate with the monitor. By this way the intelligent instrument can help the PC communicate with the industrial site in the optimum controlling system.
