三轴加速度传感器ADXL345的驱动程序,基于STM32F4.(Triaxial accelerometer ADXL345 drivers, based STM32F4.)

基于STM32单片机的profibus-dp的软件通信协议的实现(Design of profibus-DP software protocol based on STM32 MCU)

采用凌阳SECE061A板，外接发光二极管来设计一个语音跑马灯，具体功能如下： 1. 采用61板播放一小段语音。 2. 用发光二极管显示声音的大小。 3. 可以扩展为让声音一直循环播放。(By Ling Yang SECE061A board, an external LED to design a voice Marquee, specific functions are as follows: 1. By 61 board plays a brief speech. 2. With a voice the size of the light-emitting diode display. 3. Could have been extended to allow the sound loop.)

说明：  设计一个基于单片机的嵌入式系统，要求具备以下功能: 红外数据的接收及解码,红外发色电路 数码管的显示驱动控制 将接收到的红外数据进行实时显示(限于动态扫描方法) 请根据以上功能要求，进行硬件系统设计,编写软件程序并画出流程图。 信号波形解码显示都没问题，LED灯和蜂鸣器设计是有点问题的，可以删掉不用不影响。自动使用的是压缩包里第二个文件的程序，其他包里有额外的参考资料，可借鉴。(To design an embedded system based on MCU, the following functions are required: Infrared data receiving and decoding, infrared color circuit Display drive control of digital tube Real time display of received infrared data (limited to dynamic scanning method) According to the above functional requirements, design the hardware system, write the software program and draw the flow chart. Signal waveform decoding display is OK, LED lights and buzzer design is a bit of a problem, can be deleted without affecting. Automatic use of the second file in the compressed package of the program, other packages have additional reference materials, can be used for reference.)

说明：  基于51单片机，芯片STC89c52,12864液晶屏基础显示实验源代码(Based on 51 MCU, chip STC89c52, 12864 LCD basic display experimental source code)
