EM78单片机与24Cxx / 85Cxx 串行CMOS EEPROM接口I2C总线读/写的程序 ** （所有时隙均基于2MHZ晶体震荡器频率）-Tips SCM and 24Cxx/85Cxx CMOS Serial Interface I2C EEPROM Bus read/write procedures** (all slots are based on two MHZ frequency Crystal Oscillator)

详细介绍了单片机的总线设计法，讲述清除并有设计实例-Details of the MCU bus design method, and a design example about the removal

目前市场上有很多语音录放系统，如录放音玩具、录音笔等，大多采用了单片机控制一个语音芯片，再接一个FLASH存储器的结构。单片机可以控制录放时间，选取特定时间段的播放以及单多声道的录放，容易通过改变外接存储FLASH改变录放时间。 我们做的是一个简单模型，只能录放。 只需要录音和放音时的外部 ROSC 端振荡电阻不同就能改变声音的录入和播放速度，录入的时间越短音质越好，录入的时间越长音质越差 它采用模拟量直接存贮技术，因此保真度高，音质好 -Currently on the market there is a lot of voice recording systems, such as sound recording toys, sound recording pens and so on, most of the single-chip microcomputer to control the use of a voice chip, making the structure of a FLASH memory. Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct ana

程控增益线性脉冲放大器的设计。 设计了一种新型程控增益线性脉冲放大器。采用准高斯CR2RC2CR 成形电路结构,使用非易失性数字电位器和精密运放,使电路结构大大简化,抗干扰能力强,增益多级连续变化平稳,且具有温漂低、脉冲线性好等特点-Programmable gain linear pulse amplifier design. Design a new type of programmable gain linear pulse amplifier. Using quasi-Gaussian CR2RC2CR forming circuit structure, the use of non-volatile digital potentiometers and precision operational amplifier, so that greatly simplify the circuit structure, anti-jamming, multi-stage continuously variable gain stable, and has a low drift, pulse linear good characteristics

频率计，精度高，可以自动换档，一般单片机可以达到0…500k-Frequency, high precision, can automatic transmission, the general single-chip microcomputer can be 0 ... 500k
