起因：前不久跟着公司领导去给车上换装ETC，在装ETC的场地捡了一个别人扔下的ETC整体，还是带屏幕的，顺手捡了回来，准备DIY。 目的：准备先用89C52点亮试试，后续再添加/改造成其他用途的工具

准备工作:

屏幕型号

图片

LCD屏幕大小为48mm15mm，加上白色外壳有50mm23mm

确定屏幕型号为：HEM12832-19B3 1604

找了很久，终于找到这么一张有关的图片:

屏幕参数

图片

查看规格得知 Vop=6.5V,Vdd=3.3 ~ 0.2V。

驱动IC是ST7567

图片中有和我们屏幕一样的引脚编号，查看fpc pin def就行

将二者全部置放于洞洞板上，并使用线将单片机与屏幕引脚相连接

这里我接了三个按钮开关，你可以加也可以不加

很好，估计看到这儿你已经懵了，不要着急，你只需要按照我给出的连接方式连接即可

  1. 根据规格图中得知屏幕的驱动IC是ST7567，那我们直接百度download一个ST7567的示例程序，下载好之后，通过左上角的file→open→选择刚才下载的文件，导入进我们的keil5软件，
  2. 双击main.c打开程序

程序调试

再经过短暂的程序调试，我们得到了一个不多不少的显示小车的程序：

接下来需要上传我们的程序到单片机上

点击这里的小锤子：

  1. 在弹出来的框中，点击Output
  2. 勾选"生成HEX文件"
  3. 再点击ok关闭

上传程序时，需要通过stc-isp软件上传，这里就不过多赘述了。。。

打开我们的stc-isp软件

1.选择我们的单片机，我的是STC89C52RC

2.选择你的端口号，

3.默认我们的波特率为115200

当这些选择好后，还需要选择刚才生成的HEX文件

点击“打开程序文件”

在弹出的框中选择你自己的HEX文件，

以我的为例，在“桌面→12832→Objects→12832.hex”，

选中后点击打开

点击下载/编程

点击后，右侧控制台输出“正在检测目标单片机 ...”

我的单片机需要将电源开关关闭再打开便可以上传了，


操作成功！！！
