measured-frequency-meter

This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:

说明：  利用定时/计数器T0从P1.0输出周期为1s的方波，让发光二极管以1HZ闪烁，设晶振频率为12MHz(The use of timer/counter T0 from P1.0 output cycle square wave 1s, so that the light-emitting diodes 1HZ blinking, set the crystal frequency is 12MHz)
