蜂鸣器实验

本实验演示GPIO 驱动蜂鸣器的实例。

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

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

（3）重新编译完毕。

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

“GPIO.OUT”文件，点击【打开】。

（5）将蜂鸣器旁边的23J0 两针跳线座短路。点击【Debug】􀃆 【Run】或左侧快捷键

图标，全速运行。即可听到蜂鸣器发出“嘟嘟”的声音。

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。-Buzzer experiments

This experiment demonstrates GPIO driver buzzer instance.

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

(2) Click on the [project] 􀃆　[Open ...] to open the BELL "file folder" GPIO.PJT.

(3) re-compile is completed.

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

"GPIO.OUT file, click [open].

(5) the buzzer next to 23J0 two-pin jumper seat short circuit. Click [Debug] 􀃆 , [Run] or the left side of keyboard shortcuts

Icon, and run at full speed. You can hear the buzzer "beep" sound.

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 board and emulator.
