nios II--实验3——led 100M软件部分

软件开发

参照实验二(led),该实验与实验二(led)的不同之处在于系统的时钟由50M提成为100M。运行结果,在调试窗口输出Hello from Nios II!,并且板上的四个LED灯流动显示,表明测试成功!通过此实验证实,板子支持的运行频率足够高,可达到100M。

实验代码

/*

* "Hello World" example.

*

* This example prints 'Hello from Nios II' to the STDOUT stream. It runs on

* the Nios II 'standard', 'full_featured', 'fast', and 'low_cost' example

* designs. It runs with or without the MicroC/OS-II RTOS and requires a STDOUT

* device in your system's hardware.

* The memory footprint of this hosted application is ~69 kbytes by default

* using the standard reference design.

*

* For a reduced footprint version of this template, and an explanation of how

* to reduce the memory footprint for a given application, see the

* "small_hello_world" template.
