在万利199元开发板实现了STM32的定时中断功能，1秒钟产生一次中断，并且控制led在中断时闪烁。(199 yuan in Wanli STM32 development board implements the timer interrupt function, a second generating an interrupt, and interrupt control led flashes.)

Using weighted model nodes in the network strength and weight are power law distribution, Including the generalized cross-correlation function GCC time delay estimation, Conducted through virtual array DOA estimation.
