【实例简介】HC32F460的USB例程

个人收集的各种串口电路图,程序,讲解比较详细,对初学者应该帮助比较大(Personal collection of various serial circuit, procedures, explained in more detail, for beginners should help more)

用C8051F020实现正弦波的程序设计(Program designed to use the C8051F020 achieve sine wave)

ds18b20的温度显示跟序列号显示的程序(temperature ds18b20 shows the program with the serial number)

ADI公司的AD4111是具有±10V和0 mA至20 mA输入和明线检测功能的低功耗 24 位 Σ-Δ ADC,集成了模拟前端(AFE),还集成主要模拟和数字的信号调理区快,为每个模拟输入通路配置成八种单独建立图,最大通路扫描速率6.2 kSPS(161 μs),嵌入的2.5V低漂移(5 ppm/℃)能隙基准电压降低了外接元件数量,单电源5V或3.3V工作,工作温度?40℃ 到 +105℃,主要用在过程控制PLC和DCS模块.本文介绍了AD4111主要特性,功能框图以及评估板EVAL-AD4111SDZ主要特性,框图,电路图,材料清单和PCB设计图.(The AD4111 is a low power, low noise, 24-bit, sigma-deltaanalog-to-digital converter (ADC) that integrates an analog front end (AFE) for fully differential or single-ended, high impedancebipolar,10 V voltage inputs, and 0 mA to 20 mA current inputs. The AD4111 also integrates key analog and digital signalconditioning blocks to configure eight individual setups for each analog input channel in use. The AD4111 features amaximum channel scan rate of 6.2 kSPS for fullysettled data.)

51单片机与DAC芯片TLC2543的接口仿真，包含源程序、proteus仿真，以及芯片资料，望大家喜欢。(TLC2543 DAC 51 and the interface chip simulation, including source code, proteus simulation, and chip information, hope you like it.)

用整数存储私有成员：年、月和日。为类提供构造函数，能够对各成员进行初始 化，但出现错误的初值时, 成员为2000-1-。也可以不在不提供任何初值的情况 下日期为2000-1-1。另外可以用一个Date 对象进行初始化，成员函数应实现以 下功能： （1） 对所有成员一次性赋值，也能对某个成员单独赋值，能够一次返回所有成 员的值，也能单独返回某个成员的值 （2） 可以按照mm-dd-yyyy 格式输出日期。 （3） 有成员函数nextDay（），用于将日期增加一天(Integer stored the private Members: year, month, and day. Class provides a constructor to initialize the members, but the wrong initial value, members 2000-1-. The date can also be not the case does not provide any initial value 2000-1-1. Also available on a Date object is initialized, the member function should achieve the following functions: (1) all members of the one-time assignment, can also be a member of a separate assignment, to return once the value of all the members, but also separate return a The members of the value (2) according to the date of mm-dd-yyyy format output. (3) member function nextDay () for additional day date)

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 } )

用AT89C52实现的核废弃监测仪,自己写的，已经在用了，呵呵(AT89C52 to nuclear waste with the monitor, he has written, has been used, huh, huh)
