使用嵌入式系统的绘图 API 函数。首先，在屏幕上绘制一个圆角矩形和一个整圆。然后，再在屏幕上无闪烁的绘制一个移动的正弦波。-use of Embedded System mapping API function. First, the screen drawing a rectangle and a fillet entire round. And then on the screen without drawing a flicker of movement of sine wave.

嵌入式stm32通过串口1与NFC模块通信，NFC模块读取mifare卡信息，将此信息最终通过串口2打印到PC端屏幕，同时ucos提供多任务功能，LED1和LED2以多任务方式闪烁-Embedded stm32 1 and the NFC module through the serial port communication, NFC module reads mifare card information, this information is the final print to 2 P
