Button_Test实验

=== === === === === === === === === === === === === === === =

本实验实现通过扩展IO来接收KEY1和KEY2的中断，并显示在超级终端上。本例程有两种运行方式。

Button_Test IN RAM 将程序下载到SDRAM中调试。

Button_Test IN Flash 将程序烧写到Nor Flash中。上电自动运行。

===========================================================================================

程序运行成功之后，



超级终端上将显示：

External Interrupt Test Example

此时用户可以按实验箱上的KEY1按钮和KEY2按钮来触发中断。如：

Eint0 interrupt occurred.

EINT1 interrupt occurred.-================================================== =========================================

Button_Test experiment

================================================== =========================================

Realize this experiment, by extension IO to receive KEY1 and KEY2 interrupt and displayed in HyperTerminal. There are two ways to run this routine.

Button_Test IN RAM will be downloaded to the SDRAM debugging.

Button_Test IN Flash program to be in Nor Flash. Power on automatically.

================================================== =========================================

After a successful run,



HyperTerminal displays:
