摘要
完成了一种基于DAC0832数模转换器和单片机的LED亮度控制系统。整个系统以单片机为控制核心,通过控制D/A转换器DAC0832、多路电子开关以及电压保持等电路实现对多个发光体亮度的连续控制。
The control system on LED lightness base on DAC0832 and MCU is designed in this composition. DAC0832 transform numeral to simulation and control the lightness of illuminant. The MCU is the core of this design, it control D/A conversion DAC0832 transforming data, it also control multiplex electron switch and the hold vohage circuit to make the lightness change gradually. The system has advantages of little elements, universal circuit. It can be extend to more complicated system for controlling neon light.
