设计一种多功能波形发生器，以C8051F040单片机为控制器，控制波形发生器MAX038和功放实现输出正弦波、方波、三角波。该多功能波形发生器使用键盘调整波形频率，通过液晶显示屏显示频率，使用键盘选择不同的功能模式，实现外测电压的信号采集、数据存储和波形再现；可以实现USB串口传输并将接收到的信号进行波形再现。采集和由串口接收到的数据可通过I2C总线方式存入数据存储器中，也可以在单片机内部存储器中存入波形数据，再将其显示。

The multifunctional waveform generator is designed,which takes the C8051F040 MCU as the core to control the MAX038 and the power amplifier,and output sinusoidal,square,triangle waves. The frequency of wave,which can be adjust?ed by keyboard,is shown on the liquid crystal display (LCD). Different modes are chosen by keyboard to collect the signal, storage the wave data from input voltage and reconstruct the waveform. The generator can also realize USB serial transmission and reconstruct the waveform of the received signal. The collected and the received data can be stored in the data memory through I2C,or stored in the built?in memory of MCU and then display it through LCD.
