定时器0 实验

F2812 上有3 个 32 位的 CPU 定时器，本程序主要对 CPU 定时器 0 进行操作，

100MS 产生一次中断。使用时，按以下步骤进行：

（1）点击“CCS”，启动Code Composer Studio 开发环境

（2）点击【project】􀃆 【Open…】打开“CpuTimer0”文件夹下的“CpuTimer0.PJT”。

（3）重新编译完毕。

（4）点击【File】􀃆 【Load Program…】，选择“CpuTimer0”文件夹下的“DEBUG”

中的“CpuTimer0.OUT”文件，点击【打开】。

（5）点击【Debug】􀃆 【Run】或左侧快捷键图标，全速运行。在定时器中断子

函数中，我们打上断点，当定时器0 产生中断时，CCS 就会停在断点处。如下图所示。

注：如果发现程序不能正确运行或程序跑飞，可点击CCS 中【Debug】􀃆 【Reset CPU】，

然后重新Load 程序。如果还是不能正确运行或程序跑飞，可给学习板和仿真器重新上电。-Timer 0 experiment

F2812 on three 32-bit CPU timer, this program is the main CPU Timer 0

100MS generate an interrupt. Use, follow these steps:

(1) click on the "CCS", start the Code Composer Studio development environment

(2) Click on the [project] 􀃆　[Open ...] to open the folder under "CpuTimer0 the" CpuTimer0.PJT ".

(3) re-compile is completed.

(4) Click [File] 􀃆　[the Load the Program ...] select "CpuTimer0, folder under" the DEBUG

In the "CpuTimer0.OUT" file, click [Open].

(5) Click [Debug] 􀃆 , [Run] or the left side of the shortcut icon, running at full speed. In the timer interrupt sub-

Function, we marked a breakpoint, when Timer 0 to generate an interrupt, the CCS will stop at the breakpoint. As shown below.

Note: If the discovery process can not run correctly or the program running, you can visit the CCS [Debug] 􀃆　[Reset CPU]

And then re-Load program. If you still can not run correctly or the program running, re-power on to learn bo
