M25PE10, M25PE20, M25PE40 and M25PE80 这些型号FLASH 的驱动程序-M25PE10, M25PE20, M25PE40 and M25PE80 these models FLASH driver

USB主机方式的应用可以参考CH375的资料，与计算机连接的USB设备方式（或自己做U盘）可以参考CH372 的资料。如果是读写U盘并且用量较少或者是系统集成，关心快速入门并且简单易用，那么可以参考半成 -USB host mode the application can reference CH375 information, and computer-connected USB devices (or their own to do U disk) can refer to the information CH372. If it is to read and write U disk and the amount of less or systems integration, care and easy-to-use Quick Start, it can refer to semifinished

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
