为学习单片机的初学者提供定时器代码，希望能对这些人有所帮助(To learn microcontroller for beginners to provide the timer code, hoping to help these people )

说明：  STM32外扩4*4矩阵键盘，包含原理图及源码。(STM32 extends 4*4 matrix keyboard, including schematic diagram and source code.)

说明：  DAC8571通过iic协议和msp430通信(DAC8571 communicates with MSP430 through IIC protocol)

点阵原理图，595和138，没错这就是电路板 ·OLED例程，适合12864，具体使用请根 ·台达PLC Modbus协议通信dll com控件 ·单片机红外遥控最全的资料，包含很 ·非接触式IC卡开发板源程序，包括原 ·C51实用程序（45个） I/O、定时( OLED routines, suitable for 12864, please use the specific root · Delta PLC Modbus protocol communication dll com Controls · Infrared remote control MCU most complete information, including the very · Non-contact IC card development board source, including the original · C51 utility (45) I/O, timer)

使用AVR单片机，制作的无线滚码遥控器代码。其中包括无线滚码算法实现，和加密算法实现。(use AVR microcontroller, produced by wireless remote control code rolling code. Roller including wireless code algorithm, and encryption algorithm.)

说明：  BC95开发资料，Quectel_BC95_NB-IoT_模块产品规格书，全部代码(BC95 Development Information, Quectel_BC95_NB-IoT_Module Product Specification, All Codes)

12864串口液晶,包含两个文件:lcd.c与lcd.h. 调用 void printLCD(uint8 x,uint8 y,uint8 *fmt, ... ),即可将显示的字符串发送到液晶屏显示(12864 Serial LCD, contains two documents: lcd.c with lcd.h. call void printLCD (uint8 x, uint8 y, uint8* fmt, ...), can be shown in the string sent to the LCD screen display)

包含了C8051的基本例程，如流水灯，IO口控制，蜂鸣器，串口通信等(C8051MCU example programs)

说明：  stm32单片机 TOF飞行时间 C语言程序(TOF time of flight C language program of STM32 single chip microcomputer)

用数码管显示电压，发送到串口，然后有高低电压报警，只有部分代码(Display voltage with digital tube, send it to serial port, then alarm with high and low voltage, only part of the code)
