How should I get started on writing device drivers? [closed]

别等时光非礼了梦想. 提交于 2019-11-29 18:41:39
I would like to learn how to write device drivers because I think it would be fun. I use a Mac OS X Macbook, but I also have an Ubuntu machine (running on a Mac Min). I am pretty familiar with C and currently am reading this book . I have found some links online such as Mac Dev Center . I am doing this because it would be fun. I think there would be real gratification to see hardware operate because of software I wrote. I guess what I would like is some tips or advice and guidance, and does anyone know of a list of devices that don't have drivers or can I write a driver for something that's

Using LINQ to Entity Framework with DB2

泄露秘密 提交于 2019-11-29 10:22:18
问题 Is there an IBM Driver so we can use Linq to Entity framework to connect to DB2 and generate the DB2 entities on the desinger edmx file? Any links would be greatly appreciated 回答1: 7 is out. You can install DB2 9.7 client in your pc to connect to any DB2 version. You can create edmx file to DB2 8.2 database too using this 9.7 client. While developing you might require a visual studio debugger similar to that of Scott's - Linq to SQL debug visualizer. In that case feel free to download my RV's

问题 I have written an application for Android. the main part being that it communicates via bluetooth. I have four devices: 1. Samsung Galaxy S2 2. Samsung Galaxy Gio 3.

I first wrote the bluetooth side (since that was what I had the least experience in) - and the only device I can get to work is the Netsurfer touch. It uses

Writing drivers in C#

こ雲淡風輕ζ 提交于 2019-11-28 06:48:18
I have written earlier in C/C++ but currently, I need it to convert into C#. Can anyone tell me the code/way How to write drivers in C#? Actually currently I have some problems with my old application written in C++ and we have to write the drivers of our LPT1,COM Printers and other USB drivers in C#. Simply you can't. C# produces intermediate language that is interpreted by a virtual machine (.NET). All these stuff runs in user mode and WDM drivers run in kernel mode. There is a DDK but it is not supported in VStudio either (but you can make a makefile project for compilation though). Driver

Enumerate external drives

亡梦爱人 提交于 2019-11-28 03:35:02
问题 In java, you can use File.listRoots() to get all drives in the system. I'm looking to get only the external drives, i.e. USB drives, external hard disks, optical drives, floppy, etc. Is there any way to do it in java? If not, native C++ code would be good as well. In that case, I need both Windows and Linux code. 回答1: To get file system info, use something like: import java.io.*; import javax.swing.filechooser.*; public class DriveTypeInfo { public static void main(String[] args) { System.out

What is the jdbc driver “org.gjt.mm.mysql.Driver” for?

会有一股神秘感。 提交于 2019-11-27 14:37:27
After taking over a coworker's project I noticed he was using "org.gjt.mm.mysql.Driver" as the jdbc driver for MySQL 5 instead of the more common one "com.mysql.jdbc.Driver". They both are contained in the driver I found on Maven central that appears to be the standard distribution of the driver. When I look up gjt.org I found some old site that talks about "Mark's mysql driver". http://gjt.org/ The MySQL JDBC driver was initially developed by a hobbyist. It's later donated to MySQL where they renamed the package/classname. The old classname is kept for backwards compatibility reasons, but if

Difference between JDBC Driver type numbers

点点圈 提交于 2019-11-27 12:57:35
问题 I noticed that JDBC has different Drivers like: Type 1 Driver Type 2 Driver etc.. to Type 4 Why did they get the name like Type 1, Type 2 etc.? Is there any logic? 回答1: The type number tells something about how the driver actually communicates with the database. Via ODBC API. Via DB vendor specific API (using JNI calls on e.g. a DLL file in Windows). Via generic network protocol (using sockets with e.g. TCP/IP protocol). Via DB vendor specific network protocol (still with sockets). In general
