Description: 基于单片机的语音温度计的设计
包含 源程序 原理图 PCB 源文件
先录音，能分160段(地址为00H-0A0H)。我们说话平均语速4字/秒，所以20秒我们录80字。
经过计算，每个字占2个地址。我们录音15段。
录音用S1键，放音控制用S2键。录音时按下键后开始录音,录完每段后放开按键,录音停止。
共录15段,录每段时同时用数码管提示，分别用数字1-F来表示。
录音时按住来录音，放开手停止录音。
按语音(长按等到数码管变暗放手)提示键播报温度,不按不播报。-Based on SCM voice thermometer design
Contains source program diagram PCB source files
First recording, can divide for 160 (address for 00 H-0 A0H). We speak average speed 4 words/seconds, so 20 seconds we recorded 80 words.
Through calculation, every word of 2 addresses. We recording 15 paragraph.
The recording with S1 key, and let the sound with the S2 key control. When recording after press the button to start recording, record every period after after let go of buttons, stop the recording.
Were recorded 15 segment, recorded each paragraph at the same time use the digital tube hint, respectively for the number 1-F to said.
Listen to the tape recording down, let go stop the recording.
According to speech (long according to wait until digital tube darker let go) indicates that the key temperature, not by not report.

Description: 1) 每一个进程有一个PCB，其内容可以根据具体情况设定。
2) 可以在界面设定的互斥资源（包括两种：输入设备与输出设备）的数目
3) 进程数、进入内存时间、要求服务时间可以在界面上进行设定
4) 进程之间存在一定的同步与互斥关系，可以通过界面进行设定，其表示方法如下：
进程的服务时间由三段组成：I2C10O5（表示进程的服务时间由2个时间片的输入，10个时间片的计算，5个时间片的输出）
进程间的同步关系用一个段表示：W2，表示该进程先要等待P2进程执行结束后才可以运行
因此，进程间的同步与互斥关系、服务时间可以统一用四段表示为：I2C10O5W2
5) 可以在运行中显示各进程的状态：就绪、阻塞、执行
6) 采用可视化界面，可在进程调度过程中随时暂停调度，查看当前进程的状态以及相应的阻塞队列
7) 具有一定的数据容错性-1) Each process has a PCB, its contents can be set depending on the circumstances.
2) may be in the number of interface settings mutex resources (including two types: the input device and output device)
3) the number of processes into the memory time, service time can be set on the interface
4) between processes, there are certain synchronization and mutual exclusion relationship can be set via the interface, which represents the method is as follows:
The service time of the process is comprised of three fields: I2C10O5 (the service time of the process from the input of the two time slice, the calculation of the 10 time slices, five time slices output)
Interprocess synchronization: W2, said that the process need to wait until after the end of the P2 process execution can run a segment
Therefore, inter-process synchronization and mutual exclusion relations, service time can be unified in four to: I2C10O5W2
5) can display the status of each process running: Ready, blocking, execut

Description: 很好的东西，用硬件实现的8路数码显示抢答器，有仿真和硬件pcb电路。很好的东西值得收藏。具体功能如下：
（1）抢答器同时供8名选手或8个代表队比赛，分别用8个按钮S0 ~ S7表示。
（2） 设置一个系统抢答指示灯，一个清除和抢答控制开关S，该开关由主持人控制。
（3） 抢答器具有锁存与显示功能。即选手按动按钮，锁存相应的编号，并在七段数码管上显示选手号码。选手抢答实行优先锁存，优先抢答选手的编号一直保持到主持人将系统清除为止。
-Good things, with 8-way digital hardware implementation show Responder, a simulation and hardware pcb circuit. Good things worthy of collection. Specific functions are as follows:
(A) Responder same time for eight players or eight team competition, respectively, with eight buttons S0 ~ S7 representation.
(2) to set up a system to answer in light, a clear and Responder control switch S, the switch is controlled by the moderator.
(3) Responder has a latch and display capabilities. That players press the button, the latch corresponding number, and in the seven-segment digital tube display player number. Players Responder implement priority latched priority answer the player s number has remained to host the system cleared.

Description: BK9520是用于无线麦克风的芯片组，包括V段发射芯片BK9521、V段接收芯片BK9522、U段发射芯片BK9523和U段接收芯片BK9524。V段频率覆盖160~270MHz，U段频率覆盖500~980MHz。
BK9520采用数字调制和高性能音频ADC和DAC，配合极低延迟的音频编码器，实现了高保真的数字音频传输，可以应用于视唱、舞台演出以及教学系统。由于BK9520在单芯片上实现了从射频到基带的完全集成，同时省却了压扩器，这样可以显著减小系统的PCB尺寸，极大的提高生产可靠性。(BK9520 is a chip set used for wireless microphone, including V segment transmitter BK9521, V segment receiver chip BK9522, U segment transmitter chip BK9523 and U segment receiver chip BK9524. The frequency of the V segment covers 160~270MHz, and the frequency of the U segment covers 500~980MHz. BK9520 uses digital modulation, high-performance audio ADC and DAC, and very low latency audio encoder to achieve high fidelity digital audio transmission. It can be applied to solfeggio, stage performance and teaching system. Because BK9520 realizes the integration from radio frequency to baseband on single chip, and saves the companding device, so that the PCB size of the system can be significantly reduced, and the production reliability can be greatly improved.)
