用keilC 开发的基于nRF24LE1的wifi收发程序，已经用于实际数据传输系统(keil C wifi nRF24LE1)

51环境的超声波程序，keil直接完美运行，需要复制到程序中(51 microcontroller ultrasound procedure can be run directly keil)

说明：  基于无人机，组合导航实现联邦滤波器。代码(UAV-based, integrated navigation filter to achieve Federation. Code)

51单片机编程器制作资料。内有pcb，原理图，物料清单，hex文件。自制成功(51 Microcontroller Programmer production of information. There pcb, schematics, BOM, hex file. Self-made success)
