  • Easy 51Pro v2.0簡易編程器

    ·這是聶志強(qiáng)的辛勤工作,他的郵件nie_zq@163.net改動(dòng)后的硬件不再需要轉(zhuǎn)換開關(guān),5V電源從USB取電,編程高壓VPP12V從MAX232中取出,不需要特殊升壓電路。其中包含精美PCB文件,注意三極管BC547的b級(jí)不在中間。你也可以自由修改PCB文件。Easy 51Pro v2.0宇宙版 | |------軟件 | |------Easy 51Pro

  • 基準(zhǔn)電壓的溫度漂移研究應(yīng)用筆記

    Abstract: A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltagereferences, of course, are subject to errors caused by many external factors. One causeof these major errors istemperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. Thisapplication note describes how references respond to temperature changes, and how self-heating can cause a voltagereference to operate outside its recommended temperature range. Once understood, this knowledge can then be used toavoid making this design error.

  • 電源供應(yīng)器與數(shù)字電位器校準(zhǔn)應(yīng)用筆記

    Abstract: A resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solves the problem of adjusting a power supply. For easier automatic calibration, a mechanical pot can be replaced witha digital pot. This application note presents a calibration solution that uses a digital pot, because digipots are smaller, do not movewith age or vibration, and can be recalibrated remotely. This proposed solution reduces the susceptibility of the system to thetolerance of the digital pot's end-to-end resistance, making the solution optimal fordesigners. This application note also explainssome of the equations required to calculate the resistor chain values and to use a digital pot in this way. A spreadsheet withstandard reisistor values is available for easy calculations.

  • MAX7456在可視倒車?yán)走_(dá)中的應(yīng)用

    為解決傳統(tǒng)可視倒車?yán)走_(dá)視頻字符疊加器結(jié)構(gòu)復(fù)雜,可靠性差,成本高昂等問題,在可視倒車?yán)走_(dá)設(shè)計(jì)中采用視頻字符發(fā)生器芯片MAX7456。該芯片集成了所有用于產(chǎn)生用戶定義OSD,并將其插入視頻信號(hào)中所需的全部功能,僅需少量的外圍阻容元件即可正常工作。給出了以MAX7456為核心的可視倒車?yán)走_(dá)的軟、硬件實(shí)現(xiàn)方案及設(shè)計(jì)實(shí)例。該方案具有電路結(jié)構(gòu)簡單、價(jià)格低廉、符合人體視覺習(xí)慣的特點(diǎn)。經(jīng)實(shí)際裝車測(cè)試,按該方案設(shè)計(jì)的可視倒車?yán)走_(dá)視場(chǎng)清晰、提示字符醒目、工作可靠,可有效降低駕駛員倒車時(shí)的工作強(qiáng)度、減少倒車事故的發(fā)生。 Abstract:  A new video and text generation chip,MAX7456,was used in the design of video parking sensor in order to simplify system structure,improve reliability and reduce cost. This chip included all the necessary functions to generate user-defined OSDs and to add them into the video signals. It could be put into work with addition of just a small number of resistances and capacitors. This paper provided software and hardware implementation solutions and design example based on the chip. The system had the characteristics of simplicity in circuit structure,lower cost,and comfort for the nature of human vision. Loading road test demonstrates high video and text display quality and reliable performance,which makes the driver easy to see backward and reduces chance of accidents.

  • 基于單片機(jī)AT89C51的MP3播放系統(tǒng)的設(shè)計(jì)方案

    提出一種基于單片機(jī)AT89C51SND1C的MP3播放系統(tǒng)的設(shè)計(jì)方案。單片機(jī)集成了專用的解碼器,使用K9F1208閃存作為外存儲(chǔ)器,放音電路采用CS4330,存儲(chǔ)文件通過播放器上的USB接口設(shè)備從PC機(jī)上直接下載,液晶顯示采用LCD1602。方案設(shè)計(jì)簡單,性價(jià)比高,低功耗,易擴(kuò)展。由于采用的是通用單片機(jī)實(shí)現(xiàn)的,可以很容易地移植到其他微控制器系統(tǒng)中,有很強(qiáng)的市場(chǎng)競(jìng)爭(zhēng)能力和實(shí)用價(jià)值。 Abstract:  A MP3 player design based on microchip AT89C51SND1C was presented, which used K9F1208 Flash chip as the memory circuit and used CS4330 as play chip. Storage files were download from PC through USB interfaces player on the device,and the LCD/602 was used as display screen. This system had characteristics of simple design,low power,easy expand,low cost and high recognition. Using of universual microchip make it easy to transplant to other microcontrol system,and have strong market competitiom and practical value.
