基于51单片机实现定位，并通过sim900a把定位信息发送到指定手机(base on 51 chip,send location to phone)

STM32F103ZET6移植官方RT-Thread嵌入式操作系统框架(STM32F103ZET6 Porting Official RT-Thread Embedded Operating System Framework)

说明：  GD32 SPI 主从通信，通过片选IO启动传输，单次最大传输64K(GD32 SPI master-slave communication)

asm_best_practices，学习asm很好的资料，经典实践学习，可下载学习参考(asm_best_practices, very good information to learn asm, classical experiential learning, downloadable learning information)

基于51单片机的TDC-GP21温度采集程序(Based on 51 single-chip temperature acquisition procedures TDC-GP21)

STC单片机驱动TLS3001LED芯片源码(STC microcontroller chip driver source TLS3001LED)

51单片机的独立键盘，包括都懂消除，松手检测(Independent of the keyboard)

本程序可以读取电离层IONEX数据，可以运行，程序流畅简洁，清楚易懂!!(The program can read the ionosphere IONEX data, you can run the program smoothly simple, clear and understandable!!)

通过WM_DEVICECHANGE来检测u盘的传播者源代码(through WM_DEVICECHANGE to detect u site promoters source code)

说明：  基于51单片机设计的万年历，采用LCD1602实现时间的显示（年月日时分秒）时间以及闹钟的设置(Based on the calendar designed by 51 single chip computer, LCD1602 is used to realize the display of time (year, month, day, hour, second) and the setting of alarm clock.)
