基于TFT-LCD的多路实时采集显示系统研究.

With the development of electronic technology, TFT-LCD has been widely used in embedded systems. The system designed makes use of seven-inch TFT-LCD with PIC18F4520 microcontroller to achieve real-time multi-channel input voltage acquisition, and ultimately dynamic displays the curve shape changes of multiple voltages on TFT-LCD, the visual effect is perfect. To expand dynamic range of the input voltage, the system sets up signal conditioning modules, and system can be adapted to a variety of different input voltage range. [ABSTRACT FROM AUTHOR]
