It takes a long time to write a device driver, and you should also be prepared that debugging it can take a long time.
Necessary
- - a program for writing drivers;
- - emulator.
Instructions
Step 1
If you are new to developing device drivers, read the tutorial on how to create one. When choosing literature, pay special attention to the platform for which the device driver is intended, as this is of fundamental importance. Also, it will not be superfluous to consolidate knowledge of object-oriented programming, this will help you better understand the aspects of software development for devices.
Step 2
Go to the programmatic part of the device driver assembly. You need to download a software development tool such as Driver Development Kit if you are creating drivers for the Windows operating system. The program also has more convenient counterparts, for example, Numega Driver Studio. Also, most programs for creating drivers for Windows are paid, which makes it difficult to determine in advance whether this development tool is right for you.
Step 3
In cases where you write drivers for Ubuntu operating systems, use the Linux Device Driver Kit software. You can also download all the necessary programs on the Internet from the official websites of the developers.
Step 4
Write the device driver code. This can take quite a long time depending on the complexity of the equipment. Check the written code for bugs, check its work on the emulator in the environments in which you are going to use it.
Step 5
Compile the written code into an installation file, write it to disk along with the source code, which, quite possibly, you will need more than once to debug its work in the operating system taking into account updates. Check the operation of the driver on several computers at once so that you do not have to rewrite it many times in the future.
