STM32F407，2016年电子设计大赛D题，实现SPWM逆变电源(STM32 implementation of SPWM)

基于LPC1768的串口控制台程序，使用的是宝马1768开发板。需要外接：串口、lcd1602；需要开发板模块：串口、A/D转换、五向键、I2C、rtc、定时器、内置512kE2PROM、GPIO。已完成测试，开机需输入密码：012345；可使用 , 或 . 键上下切换输入过的命令。可设置、显示时间日期及闹钟，可更改密码。个人开发，引用需注明CJ right.(This project is a serial console program based on LPC1768 ARM chip , its use of Baoma 1768 development board. Need external: serial port, LCD1602 module the need of develop board module: serial port, A/D conversion, joystick , I2C, RTC, timer, built-in 512k E2PROM, GPIO. Has completed the test, the boot need to enter the password at the first: 012345 can use the key of , or . to up and down switching input over the command. Can set, display the time date and alarm clock, can change the password.Personal development, please respect the copyright.)

说明：  基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)
