QTQCircuit

这是用c语言写的利用扬声器放歌的程序,可以编译一下就可使用(useful)

说明：  串口通信C8051F120 实现，1起始位，1停止位，无校验(Serial Communication C8051F120 Realization, 1 Start Bit, 1 Stop Bit, No Check)

带主动两轮主动差速的双电机PID调速模块，实现对电机的调速，尤其可以适用于对后轮双独立电机驱动方式的主动差速调节。(The dual motor PID speed regulation module with active two wheel active differential can realize the speed regulation of the motor, and can be applied to the active differential regulation of the driving mode of the dual motor of the rear wheel.)

基于51单片机 DDS 的信号发生器设计 （有源代码）(51 MCU-based design of DDS signal generator (source code))

Multisim10的DAC原理仿真演示。采用两个计数器级联成8位计数器，然后进行DAC转换。转换前后的结果分别用数码管和示波器显示。对理解DAC的原理非常有帮助。(This simulation contains two digital counters to generate 8-bit output to DAC, both digital number and analog values are dispayed. It is helpful to understand the principal of DAC.)
