3-digital-voltage-meter
51单片机运用PCF8591实现数模莫属转换(i2c协议)
1利用PCF8591 串行A/D 转换器转换电位器输入模拟电压,并在LED数码管上显示电压值(精确到2 位小数),实现数字电压表功能。
2在基本部分基础上,利用 PCF8591 的D/A 通道实现一个固定频率的方波(频率范围10~50Hz),并在虚拟示波器上输出。(51 MCU using PCF8591 to realize the digital to analog conversion (I2C) is
1 using PCF8591 serial A/D converter to convert the input analog voltage potentiometer, and in the digital tube LED display voltage values (accurate to 2 decimal places), the realization of digital voltage meter function.
2 in the basic part of basis, the realization of a fixed frequency Fang Bo using D/A channel PCF8591 (10~50Hz frequency range), and the output in a virtual oscilloscope.)
