RGB Colour Wheel for Visual Basic

STM32F407信号发生器输入一个正弦波，AD采样，DA输出，系统频率应该是输入的波形的频率的10倍以上保证输出波形的完整性，系统的输出频率可以使用示波器测试出。(Stm32f407 signal generator input a sine wave, AD sampling, Da output and system frequency should is 10 times the frequency of the input waveform to guarantee that the above output waveform of integrity, the output frequency of the system can use oscilloscope to test out. )

STM32 SPI程序 感觉还不错 大家可以试试看(STM32 SPI program I feel pretty good we can give it a try)

modbus规约通讯测试小工具-工作空间。利用mfc实现modbus串行通信(Modbus protocol communications test tool- work space. Using MFC to achieve MODBUS serial communication )

通过MFC实现上位机与下位机的串口通讯，可自配置。(Through MFC to achieve the host computer and the next bit machine serial communication, self configuration.)

说明：  24C08多花样流水，采用51开发板，编程使LED呈流水灯，初学者的好例子。(24C08 multi-pattern, running water, with 51 development board, program the LED lights were water, a good example for beginners.)

利用单片机进行时钟的设计，并且用1602液晶显示( The use of MCU clock design, and liquid crystal display with 1602)
