用C实现广告灯箱自动装置1、直流电机控制系统，控制广告牌的升降。 2、定时翻转广告，可由按键设定时长。 3、时间设置，5：00-22：00正常工作，其余时间不工作，时间可以调整。 4、到达广告的边缘部分广告停止翻转。 5、广告可以由按键设置升/降。 6、白天时间广告灯不亮，光线较暗时广告灯才亮，测试灯的好坏时可以手动控制灯光。 7、断电时保存时间及按键的设置，使广告牌到达边缘部分。 -C implementation using automatic device 1 advertisement light box, DC motor control system, control the rise and fall of advertising. 2, ads from time to time reversal, length of time set by the keys. 3, time set ,5:00-22: 00 normal job, the rest of the time does not work, time to adjust. 4, Get ads ads stop some of the edge flip. 5, ads can be set up by the button/drop. 6, ads during the day time lights are not bright, low light only bright lights when the ads to test the quality of light can control the lights manually. 7, when power-off time and save the settings button so that the edge part of advertising arrival.

基于C8051F340的SD卡读写，移植了FATFS的文件系统。可以实现文件的读写。本人验证通过，可对有文件系统的SD进行读写。-Based on C8051F340" s SD card reader, transplant FATFS the file system. File read and write can be achieved. I verified by, a file system can read and write SD.

SD 卡，基于 FATFS 库 STM32F103RC 接口的代码示例。 你可以看到通过 SPI 接口的单片机与 SD 卡的软件连接。 使用 FATFS，您可以使 folfer，写入和读取文件在 SD 卡很容易......

SD卡的源码，希望这个资料能帮上大家，-sdmmc

L298N是ST公司生产的一种高电压、大电流电机驱动芯片。该芯片采用15脚封装。主要特点是：工作电压高，最高工作电压可达46V；输出电流大，瞬间峰值电流可达3A，持续工作电流为2A；额定功率25W。内含两个H桥的高电压大电流全桥式驱动器，可以用来驱动直流电动机和步进电动机、继电器线圈等感性负载；采用标准逻辑电平信号控制；具有两个使能控制端，在不受输入信号影响的情况下允许或禁止器件工作有一个逻辑电源输入端，使内部逻辑电路部分在低电压下工作；可以外接检测电阻，将变化量反馈给控制电路。使用L298N芯片驱动电机，该芯片可以驱动一台两相步进电机或四相步进电机，也可以驱动两台直流电机。-L298N is produced by ST a high-voltage, high current motor driver chip. The chip uses 15-pin package. Main features are: high voltage, the maximum working voltage up to 46V output current, instantaneous peak current up to 3A, continuous operating current of 2A rated power of 25W. Contains two H-bridge high-voltage high-current full-bridge driver can be used to drive DC motors and stepper motors, relay coils and other inductive load using standard logic level signal control has two enable control terminal, input signal without affecting the case to permit or prohibit the device work a logic supply input, so that part of the internal logic circuits at low voltage work can be an external sense res
