stm32f103 rtc每秒中断串口输出(stm32f103 rtc .every second printf out.)

系统中采用了电压反馈闭环，单片机通过内部软件产生一路SPWM控制信号，然后经过逻辑门变换电路变换成逆变全桥所需的四路驱动信号，再经专用驱动芯片TLP250隔离放大后，分别加到逆变全桥四个IGBT的栅极，进行驱动控制。(The voltage feedback closed loop is used in the system, and the single chip microcomputer generates all the SPWM control signal through the internal software, then transforms the four-way drive signal required by the logic gate transformation circuit into the inverter full bridge, and then adds to the gate of four IGBT of the inverter full bridge after the special drive chip TLP250 isolation and amplification, and carries on the drive control.)

说明：  用STM32F103C8T6的3组串口，分别连接cdebyte的无线收发模块，usar1接收到上位机命令，通过usart2向下转发，USart2接收到下位机数据，再由USart1向上转发， 实现中继转发功能。(Three groups of serial ports of stm32f103c8t6 are used to connect the wireless transceiver module of cdebyte. Usar1 receives the command from the upper computer, usar2 forwards downward, usar2 receives the data, and then usar1 forwards upward to realize the relay forwarding function.)

ADS教程 在这一章里，将介绍ARM 开发软件ADS(ARM Developer Suite)。通过学习如何在CodeWarrior IDE 集成开发环境下编写，编译一个工程的例子，使读者能够掌握在ADS 软件平台下开发用户应用 程序。本章还描述了如何使用AXD 调试工程，使读者对于调试工程有个初步的理解，为进一步的 使用和掌握调试工具起到抛砖引玉的作用(ADS Directory in this chapter, will introduce the development of software ARM ADS (ARM Developer Suite). Through the study of how the CodeWarrior IDE integrated development environment to prepare, compile a project examples, so readers can grasp the ADS software platform developed under user applications. This chapter also describes how to use the AXD debugger works, and readers for debugging project of a preliminary understanding, in order to further the use and control of debugging tools to initiate play the role)
