摘要
文章介绍以ARN17为控制器的微型热敏打印机软件设计方案。由于微型热敏打印机对控制打印时序的要求较高，以往的设计方法很难达到要求。本文在比较传统的嵌入式软件设计方法基础上，给出了一种基于嵌入式实时操作系统的控制软件的设计方法，井详细介绍各个任务模块以及相互协调的软件实现。设计的微型热敏打印机已运用于实际项目中，取得了良好的效果。文章的创新点在于将嵌入式实时操作系统引入微型热敏打印机控制软件的设计中，解决了传统设计的种种弊端，提高了打印的速度和质量。
The software design scheme of micro-thermal printer based on ARM7 is briefly introduced.For the demand of the time sequence is very high, the previous method won＇t meet the qualification. Through comparing traditional design of embedded software, the article suggests a method of a programming embedded software design based on RTOS. Then the software design of each task module and coordination between each other are given in detail.The designed micro-thermal printer is put into projects, and the effect is well. By introducing real time operating system into for control software on micro-thermal printer, the innovation of this text is that it overcome the disadvantages of traditional design, and improve the speed and quality of the printer.
