按键进入GPIO中断服务函数，并采用延时函数来控制LED的亮灭。开发环境：TKStudio。使用中断函数需在vector_cfg.h中修改对应的中断，例如：#define PIOINT1_IRQ_Handle GPIOIsr0，还需要在vector_table.c中写外部函数定义，例如：extern void GPIOIsr0 (void) -Press the button to enter the GPIO interrupt service function, and use delay

周立功LPC1752开发板配套的工程模板和配套例程-ZLG LPC1752 development board supporting the TKStudio project templates and matching routines

使用系统节拍定时器SysTick精确定时，实现LED1和LED2交替亮灭的效果。开发环境：TKStudio-System tick timer SysTick can fix time precisely. The result is LED1 and LED2 alternating on and off. Development environment is TKStudio.
