第8章 让开发板发出声音，蜂鸣器驱动 心得体会

第8章让开发板发出声音,蜂鸣器驱动 心得体会 通过学习Android深度探索(卷1)HAL与驱动开发的第8章 让开发板发出声音,蜂鸣器驱动,我加深对驱动的认识.以下主要是我对本节实验和参考在Linux驱动开发中使用PWM控制蜂鸣器中的一些见解. 先编写一个简单的蜂鸣器驱动程序,根据开发板上的硬件IO接口和Android驱动规范,在kernel中的driver目录中新建一个Buzzer文件,新建一个buzzer.c的源文 在目录下创建一个Makefile文件 先运行make clean命令清楚到编

go语言让windows发出声音，或者播放音乐

go语言让windows发出声音,或者播放音乐的例子:会发出alert警告的声音 ( 这是我应群员的求助写的, 如果你需要了解其中的调用原理或过程 或更多go语言调用win32api的资料,加群: 218160862 , 答案我告诉你) package main func main(){ winSound() } // golang 让windows发出警告的声音  todo 需要完善播放mp3之类 func winSound(  )  { funInDllFile, err := syscal

VB调用API函数

API函数快速入门--怎样在VB中声明和使用API函数-- 一.在VB中声明API函数有两种方法:如果我们只在某个窗体中使用API函数,我们可以在窗体代码的 General部分声明它: 声明的语法是: Private Declare Function ... Private Declare Sub..... 这里必须采用Private声明,因为这个API函数只能被一个窗体内的程序所调用. 如果我们的程序有多个窗体构成,而且我们需要在多个窗体中使用同一个API函数,就需要在模块中 声明了. 先添加

第8章 让开发板发出声音，蜂鸣器驱动

第8章让开发板发出声音,蜂鸣器驱动 心得体会 在目录下创建一个Makefile文件 先运行make clean命令清楚到编译生成的一些工程文件,执行make命令,重新编译驱动程序.将编译生成的buzzer.ko内核镜像文件拷贝出来,adb push buzzer.ko /fpga/moudles 然后插入内核镜像文件到系统中,insmod buzzer.ko,并且装载设备驱动程序,mknod  /dev/buzzer c 248 0 现在就可以在库层直接编写C/C++文件来调用这个驱动程序,这个

第八章 让开发板发出声音：蜂鸣器驱动

这一章的主要内容是让开发板发出声音——蜂鸣器驱动,在Linux驱动开发中重点也学习了这一部分内容,同时最后我们小组的考核内容是通过中断控制蜂鸣器发七个音符的音. 这一部分中,要中断控制蜂鸣器,在中断和蜂鸣器代码的基础上进行增加.中断与蜂鸣器的代码不变,在中断的测试代码中,首先要定义七个音符,之后将开发板上的七个键与七个音符相连接,再将七个音符的转换与蜂鸣器相连接,来达到所需的效果. 核心代码: int main() { int fd,fd1; int div; int keyval; fd1 =

OAuth2.0学习（5-4）新浪开放平台-微博API-使用OAuth2.0调用API

使用OAuth2.0调用API 使用OAuth2.0调用API接口有两种方式: 1. 直接使用参数,传递参数名为 access_token URL 1 https://api.weibo.com/2/statuses/public_timeline.json?access_token=abcd 2.在header里传递,形式为在header里添加 Authorization:OAuth2空格abcd,这里的abcd假定为Access Token的值,其它接口参数正常传递即可. 注:所有的微博开放

调用API接口下载腾讯CDN访问日志

公司使用腾讯cdn为网站静态内容加速,由于业务需求,需要每天下载昨天的日志(因为腾讯方面给出回复,访问日志会有2个小时或以上时间的延迟,所以不建议下载当天日志,所以每天统计前一天的日志以做分析).因为cdn是由运维来管理,但是这个需求是业务的,如果每天都由运维进行下载,再通过邮件或其他工具发送,可能就显得麻烦.所幸腾讯CDN提供了API接口,因此采用shell脚本调用API进行下载的方式,定期下载日志,这样只要业务人员运行这个脚本就能自行下载日志,解放了运维的工作. #!/bin/bash ##

32位汇编第四讲,干货分享,汇编注入的实现,以及快速定位调用API的数量(OD查看)

32位汇编第四讲,干货分享,汇编注入的实现,以及快速定位调用API的数量(OD查看) 昨天,大家可能都看了代码了,不知道昨天有没有在汇编代码的基础上,实现注入计算器. 如果没有,今天则会讲解,不过建议把昨天代码熟悉一遍(课程是紧跟着来的,请不要拉下任何一天,因为今天的知识, 可能就和昨天的知识挂钩,昨天的知识,和前天的挂钩.....,当然你如你懂汇编,不是新手,那么则可以直接往下看) 一丶远程线程注入,和汇编远程注入的区别 昨天的代码,大家可能看了(没看也没有关系,就是远程线程注入的代码,开发角
