C8051F320红外发射接收程序
基于C8051F系列单片机的无线收发电路设计
1．1 发射电路 监测终端与探测节点的硬件电路相似，监测终端通过液晶显示探测节点的编号、所传输的数据等信息并通过5 V开关电源供电。而探测节点则没有液晶显示器，通过2节普通干电池构成3 V电源供电。发射电路使用单片机PCA寄存器产生3 MHz的振荡频率，直接控制LC谐振线圈进行振荡。C8051F330D单片机具有睡眠模式，可降低节点电路的功耗，其内部的编程计数器阵列(PCA0)提供增强的定时器功能，与标准8051的计数器／定时器相比，不占用额外的CPU资源。使用PCA0产生3 MHz的载波频率，以推挽方式输出，增大后级谐振回路的发射功率。1．2 接收放大电路设计 使用AD8656双运放芯片组成接收放大电路。该运放适合+2．7～+5．5 V电源电压供电，是具有低噪声性能的精密双运算放大器。AD8656型CMOS放大器在满共模电压(VCM)范围内提供250 mV精密失调电压最大值，且在10 kHz处提供低电压噪声谱密度和0．008％的低真，无需外部三极管增益级或多个并行的放大器以减小系统噪声。通过干电池提供3V单电源供电，接收放大电路。放大电路由AD8656进行两级放大，抵消线圈所感应到的信号电压幅值因距离的增加而产生的衰减，放大所接收到的微弱信号，增加无线传输距离。系统接收电路经D8656放大后的输出电压输至单片机进行A／D转换，对数据进行编解码，而未采用检波解调电路，可有效简化电路结构。
采用软件编程实现ASK调制功能节点向监测终端发送数据，当监测终端液晶屏指示“接收成功”时，表明在该距离下可以进行通信，不断增大节点线圈与终端线圈之间的距离直到不能正常接收数据为止。测试表明，有效通信距离可以达到24 cm。在探测节点通过桥接的方式与监测终端正常通信时，测得桥接节点的平均功耗约为102 mW，而探测节点间的平均桥接距离约为20 cm。 与传统无线收发模块相比。在需要大规模、密集型部署、近距离无线通信，并且电路体积、功耗、成本受限制的场合，基于C8051F系列单片机的无线收发电路有广阏的应用前景。

红外接收程序讲解
红外接收程序讲解 TYYGROUP system office room 【TYYUA16H-TYY-TYYYUA8Q8-红外接收程序讲解1、红外遥控系统通用红外遥控系统由发射和接收两大部分组成，应用编/解码专用集成电路芯片来进行控制操作，如图1所示。
发射部分包括键盘矩阵、编码调制、LED红外发送器；接收部分包括光、电转换放大器、解调、解码电路。
下面，我们将使用下面两种设备：另外，使用51单片机进行解码。
2、原理图从原理图看出，IR的data脚与51的PD2相连。
2、红外发射原理要对红外遥控器所发的信号进行解码，必须先理解这些信号。
a) 波形首先来看看，当我们按下遥控器时，红外发射器是发送了一个什么样的信号波形，如下图：由上图所示，当一个键按下超过22ms，振荡器使芯片激活，将发射一组108ms的编码脉冲(由位置1所示)。
如果键按下超过108ms仍未松开，接下来发射的代码（连发代码由位置3所示）将仅由起始码（9ms）和结束码（）组成。
下面把位置1的波形放大：由位置1的波形得知，这108ms发射代码由一个起始码（9ms）,一个结果码（）,低8位地址码（用户编码）（9ms~18ms）,高8位地址码（用户编码）（9ms~18ms）,8位数据码（键值数据码）（9ms~18ms）和这8位数据的反码（键值数据码反码）（9ms~18ms）组成。
b) 编码格式遥控器发射的信号由一串0和1的二进制代码组成．不同的芯片对0和1的编码有所不同。
通常有曼彻斯特编码和脉冲宽度编码。
XS-091遥控板的0和1采用PWM方法编码，即脉冲宽度调制。
下图为一个发射波形对应的编码方法：放大0和1的波形如下图：这种编码具有以下特征：以脉宽为、间隔、周期为的组合表示二进制的“0”；以脉宽为、间隔、周期为的组合表示二进制的“1”。
3、红外接收原理a) 波形红外接收头将38K载波信号过虑，接收到的波形刚好与发射波形相反：放大，位定义0和位定义1波形如下：4、解码原理及算法注：代码宽度算法：16位地址码的最短宽度：×16=18ms 16位地址码的最长宽度：×16=36ms可以得知8位数据代码及其8位反代码的宽度和不变：（+）×8=27ms所有32位代码的宽度为（18ms+27ms）~(36ms+27ms)对于红外线遥控对于很多电子爱好者来讲，都感觉到非常神奇，看不到，摸不着，但能实现无线遥控，其实控制的关键就是我们要用单片机芯片来识别红外线遥控器发出红外光信号，即我们通常所说的解码。
