键盘的功能，有单独键盘和行列式键盘的程序，很实用，(Keyboard functions, the determinant has a separate keyboard and keyboard procedures, it is practical,)

说明：  此文章介绍了如何自己制作9针串口，看完这篇文章之后你就可以自己制作9针串口了！(9-pin serial)

程序1：stm32程序串口2接收串口1发送程序 ，改自扩展实验11 ATK-HC05蓝牙串口模块实验程序。 程序2：zigbee串口通讯-发送字符串。 连接方式：cc2530的P02连接stm32的PA2，P03连接stm32的PA3 程序2串口一直发送“hello zigbee”字符串 mini版stm32程序1串口2接收后转发串口1原样输出。(Program 1:stm32 program serial port 2 receive serial 1 send program, change from expansion experiment 11 ATK-HC05 Bluetooth serial module experiment program. Program 2:zigbee serial communication - send string. Connection mode: CC2530 of P02 connection, STM32 of PA2, P03 connection of STM32 of PA3 Program 2 serial port has been sent "Hello ZigBee" string mini version of STM32 program 1 Serial 2 receive after forwarding the serial port 1, the original output.)

对STM32单片机内部的温度进行测量，主要靠的是内部传感器(Temperature measurement in STM32 single chip computer mainly depends on internal sensors.)

TI出品的集成RF通讯功能的低功耗单片机CC430的MPY程序。(TI' s integrated RF communication produced low-power MCU CC430' s MPY program.)

说明：  基于STM32F103ZET6的步进电机驱动器A4988的电机驱动测试程序(A4988 driver test code)

IRMCK171的FOC控制无刷电机控制原理图 IR内部资料啊(Control of IRMCK171 FOC brushless motor control schematic IR internal data)

说明：  平台:pic16f877a 环境:mplab8.33 语言:c 功能:红外遥控接收器 其他:调试已通过(Platform: pic16f877a environment: mplab8.33 Language: c function: Infrared Remote Control Receiver Others: debugging has passed)

基于xs128的入门代码，led闪烁功能的实现，可以帮助初学者很好的入门(Xs128-based entry code, led blinking function to achieve, can help beginners a good start)

基于msp430f149 的 TM1637驱动数码管程序测试OK
