插入式IC卡1608驱动，已经测试应用。需要时改变头文件就可以。(plug-1608 Driver IC card has been test application. Need to change the header files can be.)

stm32制作简易信号源，产生方波三角波和正弦波(STM32 makes simple signal source to produce square wave triangle wave and sine wave)

使用超声波模块测距，测距范围 10cm--1..2m(Using ultrasonic module to measure distance, ranging range is 10cm-1.2m.)

ESP8266硬件参考设计文件，有硬件PCB原理图，三个文件。。。(ESP8266 file,PCBSCHPDF,for learning)

stm32与fpga进行spi通信，fpga进行测频，占空比，时间间隔测量，32可控制其运行模式，并将测得结果于lcd上进行显示。(STM32 communicates with FPGA in spi. FPGA measures frequency, duty cycle and time interval. 32 can control its operation mode, and display the measured results on lcd)
