单片机模拟spi接口读写ads1242，可通过串口显示数据结果(Single chip microcomputer simulation spi interface to read and write ads1242, via a serial port to print data)

基于新唐M453的串口1数据收发和对led灯的控制，可以通过串口助手来监听看到数据变化。(Based on the new Tang serial 1 data transceiver and control of the LED light, you can monitor through the serial assistant to see data changes.)

说明：  使用555时基电路产生频率为20kHz-50kHz的方波Ⅰ作为信号源；利用此方波Ⅰ，可在四个通道输出4种波形；每通道输出方波Ⅱ、三角波、正弦波Ⅰ、正弦波Ⅱ中的一种波形，每通道输出的负载电阻均为600欧姆。限用NE555、NE5532（或LM358）、电容和电阻若干。(-Waveform generator with schematic + circuit + program)

可以实现上位机和下位机之间的串口通信，收发正常，一个简单的串口助手，应该没问题，希望和大家一起讨论。(Can achieve serial communication between the host computer and the lower computer, send and receive normal, a simple serial assistant, it should be no problem, and we hope to discuss together.)

进行速度的测量与监控，具有测速频率高，精度高，反馈效果好等优点(Speed measurement and monitoring has the advantages of high frequency, high accuracy and good feedback effect.)

基于StC89C52单片机的nRF24L01驱动及应用程序， 已经调试成功(Driver and application program of nRF24L01 based on STC89C52 MCU has been debugged successfully.)
