Location of Port mapped I/O address space

阅读更多关于 Location of Port mapped I/O address space

问题 I know access to ports in I/O address spaces requires specific IN/OUT instructions and they are not part of Physical memory( RAM) but I have not understood Where is the I/O address space actually located (Physically)? (some sort of RAM in )I/O controller? Reserved side of physical memory? 回答1: On the early X86 processors (and also the 8080, Z80 etc) I/O address space was on the same data and address bus as the memory, but was accessed by activating a dedicated IO-request pin on the CPU So

问题 I've been learning assembly language recently, and I already know how to use the in/out command. But I have some questions: where did the port addresses come from, like 0x70. How do I know how many ports my computer has and the addresses of them. I've checked the Intel developer's manual, but I can't find the answer. Thank you for your attention 回答1: There's a maximum of 65536 IO ports, and most aren't used. The IO ports that are used on a modern PC can be split into 2 categories: PCI devices

打造自己的OSC客户端，OSChina For PC v0.1_beta 发布

阅读更多关于打造自己的OSC客户端，OSChina For PC v0.1_beta 发布

自己做的osc的pc客户端，大概5月20号左右开始开工的，中间由于比较忙有两周没写了。最近看到osc上连续两篇文章说拿XX制作osc客户端，本人有点坐不住了, 花了3天时间,算是把动弹方面的功能做了个差不多。先发上来再说，后续会把其他功能完善。 # 做这个客户端，之前我想的是用#TideSdk# 做，但由于TideSdk的一些bug，让我不得不放弃TideSdk 。还白白浪费了几天时间。然后想用java，但java的webview功能方面太弱。于是就尝试了用python+pyqt 的方式。页面什么的当然是html + js +css 啦。由于是边学python和pyqt边做的，很多东西要一点点试。所以花的时间也比较长。也有很多不完善的地方，当然随着我对python的进一步熟悉，也会一步步完善。代码会在功能完善个差不多的时候开源，各位看官毋须激动。话说"no picture you say a jb". 所以图是必须的。 ps: 1：如果运行只出现白屏，请检查解压的文件目录时候含有中文字符，改成因为即可。 2：windows下运行需要MSVCP90.DLL 如果运行错误，查看c:/window/system32下面是否有MSVCP90.dll存在，没有的话从网上下载个放进去即可。源码地址: http://git.oschina.net/fantsme/oschina

问题 Is there a way to use or an alternative to InstallationManager.FindPackagesForCurrentPublisher? It looks like it is only for the phone. I know you can launch an app by creating and then launching a URI, but I need to know if the app I want to launch is installed. EDIT: The app I want to launch is by the same publisher. 回答1: If we use the LaunchUriAsync(Uri) method to launch an app, system will firstly try to launch the installed app which registered this protocol, if the target app is not

Emulate an incoming call on physical device via PC (Eclipse)

阅读更多关于 Emulate an incoming call on physical device via PC (Eclipse)

问题 I am working on an android project, and I want to be able to test my app on a physical device. The only way I can test my app is to receive incoming text messages and calls. I know I can simulate texts and calls on the emulator either via telnet or via DDMS in Eclipse. Is this possible to do the same thing without having to keep texting myself or calling myself from another device as its going to cost. I'd much prefer to do it on a device as it is much quicker than on the emulator. Thanks for
