使用STM32单片机驱动dds模块，这里的dds模块为正点原子的模块(Using STM32 MCU to drive the DDS module, where the DDS module is the module of positive atom)

这是关于电路板的设计图，方便大家下载。呵呵 (This is about the second Five-Year Plan, said a key project for the future development of a box of reference )

说明：  单片机STM32103RCT6,GD32F103RCT6,程序管脚都兼容，采集16通道的ADC数据，通过FATFS文件管理系统将数据存储到SD卡。(Stm32103rct6 and gd32f103rct6 are single-chip computers. The program pins are compatible. The ADC data of 16 channels are collected and stored in SD card through FatFs file management system.)

利用STC15单片机实现对称PWM输出，可设置频率、占空比，利用JLX12863显示。( symmetrical PWM output based on STC15 MCU， frequency　and duty cycle can be setted, use JLX12863 display.)

说明：  canopen+freertos 心跳例程(canopen+freertos Heart)

说明：  msp430基于日历系统的实现，功能实现很好(Controller calendar system based on the realization that to achieve good functional)

合泰单片机pb口输出1秒钟变换一次高低电平，用于测试定时器和端口输出指令。(holtek mcu,1 secend change I/0 _pb,high or low)

说明：  uvision 2 单片机C语言开发系统使用说明。(uvision 2 single-chip C language development system for use.)

DS1302单片机c语言和proteus仿真(Program on DS1302 by MCS-51，c and proteus。)
