Abstract
The experiment is based on the ARM Cortex-M3 microcontroller applications STM32 family practice , describes the STM32 microcontroller data acquisition hardware design and software design, data acquisition system is essential between the analog domain and digital domain link, it existence has a very important role. Focus of this paper is the data acquisition system, and the hardware part of the center of gravity of the system lies in the microcontroller . Data acquisition munication control uses a modular design, data collection munication control using the STM32 microcontroller to implement the hardware part is a microcontroller core, also includes A / D conversion module and the serial interface section. The system is responsible for data collection from the machine and answer a host mands. The input data is generated by the field generated by the analog signal , then the measured voltage 8 analog to digital conversion by analog to digital converter ADC0809, to achieve the collected data to the digital to analog conversion, and the converted data to the puter , be accepted by the puter is responsible for data processing and display results. Keil uVision4 part of the application software by C language control software, data acquisition systems , analog- to-digital conversion systems, data display, munications and other procedures designed.
