基于μClinux的微型热敏打印机驱动的实现

目前市场上的打印机产品基本上是不带操作系统的,这样使得一些能并行运行的任务只能串行运行,增加了程序运行的时间,降低了程序运行的效率,如果在操作系统上开发产品就可以将任务设计成并行的运行方式,从而使系统的资源得到充分的利用。μClinux是Linux经过裁减和优化而成的专门应用于嵌入式领域的操作系统,其针对嵌入式处理器做了专门的改良,成为嵌入式操作系统的首选。本文论述了μClinux下驱动编写的规范以及如何以驱动的方式在μClinux上实现热敏打印机的功能。

Realization of Micro Thermal Printer Driver Based on μClinux

In the current market, most printer products are not based on operating system. This makes some parallel tasks can run but in serial manner, so it increases the time of program running and reduces the efficiency of program executing. If we develop products basing on operating system, and design tasks by parallel way, we can take full advantage of system resources, shorten the time of designing and debugging, and improve the efficiency of work. uClinux is derived from Linux, it is reduced and optimized from Linux and specially used for embedded system. It makes special improvement for embedded processor, and so becomes the first choice of embedded operating system. This paper describes the driver rules of uClinux and the process of designing thermal-printer driver on uClinux.
