Point RTOS 主要是一个针对小系统开发而设计的实时操作系统。
目前，Point RTOS 仅提供对51系列及其扩展系统单片机的支持，
针对51内核函数不能重入以及51单片机的内存空间管理方式等因素，
RTOS放弃了抢先式内核的调度，而使用了时间片的调度方式，除非任务主动放弃，
否则任务将独占CPU一直运行，因而任务中必须完成对本次操作的时间片设置，即等时间的设置。-Main Point RTOS is a small system development and design of real-time operating system. At present, Point RTOS only provide for 51 series and its expansion of the system single-chip support for 51 core function should not re-entrant, as well as 51 single-chip memory space management and other factors, RTOS abandoned preemptive kernel scheduling, the use of a scheduling time slice manner, unless voluntarily chose to abandon the mission, or mission will be exclusive CPU has been running, which must be completed in the mission of this operation time slice settings, that is, the time settings.

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
