德州仪器数字DA芯片 TLV5638的STM32程序，部分宏定义，可直接使用(Texas Instruments TLV5638 the STM32 chip digital DA program, part of the macro definition, can be used directly)

ATT7053B单相计量芯片程序 ATT7053BU 是一颗带SPI 通讯接口的单相多功能计量芯片（EMU）。 芯片的工作电压范围是4.5 ～ 5.5V。 工作晶振为6MHz。(ATT7053B single-phase metering chip program ATT7053BU of a single-phase multi-function measurement chip with SPI communication interface (EMU). Chip operating voltage range is 4.5 to 5.5V. The work of the crystal is 6MHz.)

STM32 EMWIN移植成功并且已实际操作过，可以随意使用图形界面。(STM32 EMWIN transplantation success and has practical operation, can use the graphical interface.)

本历程实现了一个完整的层次状态机HSM，可根据UML方便的写出相应的状态机代码。特别适合复杂状态机的开发。(This process implements a complete hierarchical state machine (HSM), according to the UML state diagram convenient to write the corresponding state machine code. Especially for complex state machine development.)

S3C2440 TEST PROGRAMM

使用STM32的DSP库函数，对AD来的信号进行FFT变换，并显示到LCD屏上。做的是512点fft，显示240个数，且有一定的精度保证。具有很高的实时性。(Use the STM32 DSP library functions, the signal of the AD to the FFT transform, and display to the LCD screen. Do is 512 points fft, show the number 240, and there is a certain guarantee of accuracy. With real-time high.)

一块TFT屏幕的驱动程序，包括管脚的定义以及纵横方向的延展，但是没有具体的数据cmd，需要的拿走(A driver for TFT)

用STM32实现TFT显示！用的是ILI9325芯片驱动的！(With STM32 realize TFT show! Use is ILI9325 chip drive!)
