    Marlin——开源固件,3D打印控制系统。本质是一个Gcode代码解释器,接收来自上位机的控制命令或者读取存储卡中的gcode文件。生成3MF程序包

    Marlin——开源固件,3D打印控制系统。本质是一个Gcode代码解释器,接收来自上位机的控制命令或者读取存储卡中的gcode文件。把程序(固件)烧录到主板,这块主板就相当于微型电脑一般,而控制系统就相当于操作系统(这是我以前接触这块的理解)。研究Marlin代码,我觉得最好是有一些电子方面的知识,容易理解(可惜我这方面知识很薄弱,只是略懂皮毛)。

    控制系统,顾名思义,主要是用于控制主板各种行为。

    1.驱动控制板;

    2.执行队列中的命令;

    3.控制步进电机;

    4.温度控制和侦测(挤出头和热床的温度);

    5.读写SD卡;

    6.控制显示屏(LCD或触摸屏)

    Configuration.h:主要是一些定义,如波特率,打印行程, 限位开关,PID等。ultralcd.h和ultralcd.cpp:显示屏界面。watchdog.h和watchdog.cpp:看门狗。

    Marlin_main.cpp:setup()函数用于初始化工作。

    医院现有的采血管贴标传统工作方式包括手工方式和直接采购带有随机条码的试管,进行再匹配的两种方式。以患者化验任务为例,护士首先需从医院的实验室信息系统中取得患者检测的相关信息,如姓名性别、检测信息、检测日期等等,再打印每个需要检测的人试管标签,最后人工选择相应化验项目的试管并一一粘贴。当检验人数较大时,仅仅粘贴标签这一项工作都将消耗大量的时间和人力。

    本场 Chat 将带领大家通过一个实例代码,基于单片机学会打印贴标机核心控制部分的操作,也就是完成各种信息以及条形码的打印,帮助大家对控制打印的知识做到知其然,并知其所以然。

    本场 Chat 您将学到如下内容:

    1. 学会整体方案的设计
    2. 打印机工原理
    3. 文字,数字等如何打印
    4. 条形码如何打印
