基坑监测坐标位移小程序，能任意放大坐标位移。虽然小，但是是原创。多谢指教(Excavation monitoring coordinate displacement small program that can coordinate any displacement amplification. Although small, but it is original. Thank you advice)

STM32F103C8T6配套程序源码-红外发射和接收(945ccfdsd de d ffd ex xfe d dd)

STM32_F107显示U盘中图片,神舟IV号原光盘资料，MDK编译测试。(STM32_F107 Display U disk images, Shenzhou IV, the original CD-ROM, MDK compiler testing.)

这是FreeRTOS移植到STM32F0系列单片机的实例，已经验证成功，成功的驱动了LED,24L01,SPI,ADC等等外设。源码已经测试通过无误。(This is FreeRTOS transplanted to STM32F0 MCU instance, has been verified successfully, the success of driven LED, 24L01, SPI, ADC and so on peripherals. Source code has been tested correctly.)

假设P1.0口为发光二极管（共阴），其通过按键来控制是否开启(Suppose that the P1.0 port is a light emitting diode (common negative), which controls whether to turn on or not by pressing a button.)

使用485向外发送0-255的数字。 若开发板的485接收到256个字节数据，会把数据以16进制形式打印出来。(Use 485 to send out 0-255 digits. If 485 of the development board receives 256 byte data, the data will be printed in 16 form.)

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)

本例是基于STM32F407完成对。本代码主要完成MP3播放，界面显示等功能，还可在此基础上外扩点阵屏实现LED显示功能！(This case is based on the completion of the STM32F407. The code is mainly to complete MP3 playback, interface display and other functions, can also be based on the expansion of LED dot matrix screen display function!)
