1.基于DAC0832 protues 仿真的信号发生器 2.能发生正弦波，方波，锯齿波，阶跃波 3.软件用的是protues 4.程序是keil u2 编写的C语言单片机程序-Based the DAC0832 protues simulation signal generator can occur sine wave, square wave, sawtooth, step 3. Software used is protues program the keil u2 writ

通过单片机产生PWM，调节参数寄存器的值，产生不同占空比的PWM信号。若占空比的变化规律是正弦的，则滤波后可得到所需正弦波形。(The PWM is generated by the microcontroller to adjust the value of the parameter register, and the PWM signals with different duty cycles are generated. If the duty cycle is sinusoidal,

用c语言通过单片机产生方波，正弦波，三角波，锯齿波。(Produce Fang Bo, sine wave, triangle wave, sawtooth wave)
