ARM LPC2368芯片，外部中断实验的源码，通过此源码可以了解外部中断的工作原理-ARM LPC2368 chips, external interrupt source experiment, the passage of this external interrupt source can understand the working principle

lpc2368 串口接受 采用中断方式 编译环境为keil4 -lpc2368 uartprocess interrupt

LPC2368 利用外部中断对跳变沿计数，实现对方波频率的测试-LPC2368 using the external interrupt on edge counting, to achieve each wave frequency of the test
