代码说明:

最近在学习QT,学了一段时间之久就自己动手做了个音视频的播放器,这是该播放器的全部代码,里边基本都有注释,功能包括有视频切换,快进/退,音量调节(鼠标调节、键盘上下键调节),全屏切换,播放列表,打开本地文件等等,基础功能不少,但是也不多,适合初学者学习,有兴趣的朋友可以下载来看看。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • 热敏打印机驱动.rar
    【实例简介】由于网上关于热敏打印机部分的驱动源码很少,基本上只有重试这部分驱动开发的人员才有该源码,因此我整理我做过的打印机驱动分享出来,该驱动只针对打印机驱动层部分,对底层定时器,IO驱动,延时部分的驱动,相信你一定能够自行实现。如有疑问请留言。 附件为热敏打印机驱动,该驱动使用双定时器,一个定时器给步进电机使用另一个定时器给热敏机芯加热使用,该驱动可移植到任何平台打印机,前提是你必须自己实现定时器接口函数,io管教函数,mdelay(),udelay(),spi 函数等函数,该驱动打印接口函数为 prn_string(),和prn_image()函数,其中prn_image()打印图片默认扫描方式为横向扫描, prn_string()函数默认字库的扫描方式为纵向扫描方式, 源码中有纵向扫描方式转换为横向扫描算法。请仔细研究... 另外为了更加便于理解该驱动,我在附件中加入打印机部分原理图,和打印机datasheet。
