SPI通信---pic18系列单片机编程实现使用MAX7219控制4位7段数码管显示数字：0 1 2 3。(SPI communication--- pic18 series microcontroller programming using the MAX7219 control four 7-segment LED display digits: 0123.)

用stm8硬件 I2C 中断方式 发送/接收数据， 经过查阅手册和反复验证，已经完成了，话不多说，上代码。(With stm8 hardware I2C interrupt mode to send / receive data, After reviewing the manual and repeated verification, has been completed, then not much on the code.)

使用15单片机测量ne555的频率，频率范围 1--20000hz(Measuring the frequency of NE555 with 15 single chip microprocessor in the frequency range of 1-20000hz)

采用NXP出品的高集成度PN532读写芯片， 符合ISO/IEC18092（NFC）标准，兼容ISO14443（Type A、Type B）标准。采用USB接口与电脑进行通讯及供电，不但可以读取符合Mifare标准的Classics（M1、M4、MUL）和DESFire卡，还支持FeliCa卡等符合NFC规范的非接触式IC卡。(IC card and entrance guard card reading and writing)

附件为stm32f103vet6的uart和io驱动示例(Attached are examples of UART and IO drivers for stm32f103vet6)

基于STM32F103XX平台，SPI协议接口OLED屏 UI三级菜单界面(Level 3 menu interface)

IIC，驱动代码。通过封装实现模拟的IIC单片机时序。根据注释调用相关的函数即可(IIC, driver code. Through the package to achieve the simulation of the IIC microcontroller timing)

这是一个远程温度计 MCU: AT89S52 温度传感器: DS18B20 晶振: 12MHz 使用串口连接,在PC端使用"超级终端"打开 设置如下: 波特率: 4800 数据位: 8 奇偶校验: 无 停止位: 1 数据流控制: 无 电路图见Thermometer-SCH.jpg 该程序的编写参照了Keil UV2自带的便子 见EXAMPLESMEASURE 使用终端交互方式 其实,这不仅是一个测漫器, 它的时钟也非常准确.(This is a remote thermometer MCU: AT89S52 Temperature sensor: DS18B20 crystal: 12MHz to use serial port connection, in the PC client to use super terminal Open settings are as follows: baud rate: 4800 data bits: 8 Parity: None Stop bits: 1 Data Flow Control: No schematics see Thermometer-SCH.jpg the program prepared by the light of the Keil UV2 own son will see the use of terminal interactively EXAMPLESMEASURE In fact, this is not only a measured man, and it is also very accurate clock.)

说明：  MD-6H minda 3d printer firmware

ccd驱动程序,刺程序是tcd1209的驱动程序，能够修改积分时间(ccd driver stabbed program is tcd1209 driver can modify the integration time)
