光电编码器，是一种通过光电转换将输出轴上的机械几何位移量转换成脉冲或数字量的传感器。 这是目前应用最多的传感器，光电编码器是由光栅盘和光电检测装置组成。光栅盘是在一定直径的圆板上等分地开通若干个长方形孔。由于光电码盘与电动机同轴，电动机旋转时，光栅盘与电动机同速旋转，经发光二极管等电子元件组成的检测装置检测输出若干脉冲信号(Photoelectric encoder, a photoelectric conversion to the output shaft of the mechanical geometry of displacement into a pulse or digital sensors. This is currently the most widely used sensors, optical encoder is determined by the grating disk and photoelectric detection device component. Grating disc is a circular plate in such a diameter of several rectangular holes partially opened. Because coaxial photoelectric encoder and the motor, the motor rotates, the grating disk rotates with the same speed motor, the light-emitting diodes and other electronic components of the detection device detects certain pulse signal output)

基于DSP2812对于挂在一条总线上多个18B20采集温度的程序，通过读取每个18B20不同的64位编码，发送数据匹配编码来确定某个18B20，可以读取温度(Based on DSP2812 hanging on a bus for more than 18B20 temperature acquisition program by reading each 18B20 different 64-bit encoded transmission data to determine a match-coding 18B20, you can read the temperature)

stm32F103c8t6 连接HC08蓝牙串口模块与手机（安卓系统）通过蓝牙连接，并实现手机无线控制stm32F103c8t6 的GPIO口控制指示灯动作，同时stm32F103c8t6 的GPIO口控制指示灯动作后将指示灯状态通过HC08蓝牙模块回传给手机APP，并在APP上显示出来。(Connect the HC08 stm32F103c8t6 Bluetooth serial module and mobile phone (Android) via Bluetooth, mobile phone and wireless control stm32F103c8t6 GPIO port control indicator action, while the stm32F103c8t6 GPIO port control indicator after the action will light status through the HC08 Bluetooth module back to the mobile phone APP, and displayed on the APP.)

说明：  SI4463 测试可用 只需要自己更改si463的管脚就可以(The SI4463 test is available by changing the pin of the si463 itself)

板载三个灯同时亮灭，板子上可以看到灯发出闪烁的白光(On-board three lights turn on and off at the same time)

As a multicarrier transmission system Orthogonal frequency division multiplexing (OFDM) has been widely applied in wireless communication systems due to its numerous advantages like robustness against multipath fading and delay, high data rate transmission capability, high spectral efficiency, allows adaptive modulations
