51单片机常用的C程序例子。非常适合单片机控制多媒体方面的(51 SCM common example of C program. Very suitable for microcomputer control of multi-media)

一个基于C语言的51单片机多功能电子闹钟日历，支持多组闹铃和倒计时功能，自动修正闰年天数(A microcontroller-based C-51 multi-function electronic calendar alarm clock, alarm and countdown to support multiple functions, automatically correct number of days in leap year)

说明：  DAC DMA成功输出正弦波，详细说明在程序中都有备注(DAC DMA Successfully Output Sinusoidal Wave)

日常生活中经常见到的广告牌以LED流动发光的形式来增加效果，该文件就包含了流水灯的编程代码。(The billboards that are often seen in daily life increase the effect in the form of LED luminous light. The file contains the programming code of the water lamp.)

这是一个SPI 接口的1.8寸TFT操作的源代码，液晶屏控制器为ST7735,里面附带ST7735资料(This is an SPI interface 1.8-inch TFT operation of the source code, the LCD screen controller ST7735, ST7735 with inside information)

采用51系列单片机为控制核心，包括电源变换处理及分配模块，恒流源模块，单片机主控模块，键盘输入模块，LCD显示模块，数模/模数转换模块，语音模块和实时时钟模块的9个部分。通过键盘设定好需要输出的电流值后，单片机对设定值按照一定的算法进行处理，经数模输出电压控制恒流源电路输出相应的电流值(51 Series single-chip microcomputer used for the control of the core, including the processing and distribution of power transform module, constant current source module, single-chip control module, the keyboard input module, LCD display module, digital-to-analog/analog-digital conversion module, voice module and real-time Clock Module Part 9. Through the keyboard need to set output current value, single-chip microcomputer according to the settings of the algorithm processing, digital-to-analog output voltage by the control constant current source circuit output current value of the corresponding)

通过串口实时显示MOU6050数据，希望可以帮到大家(Real-time display of MOU6050 data through serial port, I hope it can help you.)

MPC5604P的RTC中断代码，设置RTC中断的时间间隔约为0.5秒，D1每隔约1秒闪一次(MPC5604P the RTC interrupt code, set the RTC interrupt interval of approximately 0.5 seconds, D1 at intervals of about one second flash once)

STM32F4系列串口接收函数,，程序已测试通过。(void USART1_IRQHandler(void) //串口1中断服务程序 { u8 Res #ifdef OS_TICKS_PER_SEC //如果时钟节拍数定义了,说明要使用ucosII了. OSIntEnter() #endif if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET) //接收中断(接收到的数据必须是0x0d 0x0a结尾) { Res =USART_ReceiveData(USART1) //(USART1->DR) //读取接收到的数据 if((USART_RX_STA&0x8000)==0)//接收未完成 { if(USART_RX_STA&0x4000)//接收到了0x0d { if(Res!=0x0a) USART_RX_STA=0 //接收错误,重新开始 else USART_RX_STA|=0x8000 //接收完成了 } else //还没收到0X0D { if(Res==0x0d)USART_RX_STA|=0x4000 else { USART_RX_BUF[USART_RX_STA&0X3FFF]=Res USART_RX_STA++ if(USART_RX_STA>(USART_REC_LEN-1))USART_RX_STA=0 //接收数据错误,重新开始接收 } } } } #ifdef OS_TICKS_PER_SEC //如果时钟节拍数定义了,说明要使用ucosII了. OSIntExit() #endif } )

说明：  180度舵机可以由按键控制，缓慢转180度(The 180 degree steering gear can be controlled by keys and rotates 180 degrees slowly)
