【STM32】使用单片机DAC产生噪声群

前期准备软件平台：基于KEIL的HAL库开发硬件平台：正点原子STM32F4探索者开发板 STM32F4 DAC 简介 STM32F4 的 DAC 模块(数字/模拟转换模块)是 12 位数字输入，电压输出型的 DAC。DAC 可以配置为 8 位或 12 位模式，也可以与 DMA 控制器配合使用。...

单片机：DAC数模转换实验(内含DAC介绍+PWM介绍+硬件设计+软件设计+原始代码)

注：DAC芯片贵，一般用PWM代替DAC1.DAC介绍： 1.分辨率：指输入数字量的最低有效位（LSB）发生变化时，所对应的输出模拟量（电压或电流）的变化量。它反映了输出模拟量的最小变化值。分辨率与输入数字量的位数有确定的关系，可以表示成FS /࿰...

4.8 51单片机-PCF8591(ADC/DAC)转换芯片

4.8 PCF8591(ADC/DAC)转换芯片4.8.1 原理图当前实验板上没有PCF8591芯片，这里采用外接模块的形式使用。通过原理图得到的重要信息: PCF8591芯片地址线全部接GND。也就是当前模块的地址固定为: 10010004.8.2 PCF8591模块功能介绍在一个完整的...
