用于STM32实时时钟程序,可以代PC8563使用.,Real-time clock procedures for STM32

NRF2401 STM32 收发例程 注意，这里要用2个NRF24L01模块同时工作，才能实现。我们测试时基于两套开发板的- NRF2401 STM32 receive routine Note that this use two NRF24L01 modules at a time, can be achieved. Our development board based on two sets of test

在用STM32做开发或学习的时候难免需要同时采集多路AD信号(When do with STM32 development or learning inevitably need to gather multi-channel AD signal at the same time)
