高职物联网屏幕二维码

高职物联网模拟4

题目

利用提供的 NBIOT 通用库项目工程，找一块 NB-IOT 模块进行开发。
**任务要求： **
1. 运行二维码识别生成具，在文本信息输入框中，输入“2021 年物联网高职赛项”+【工位号】+“号工位”，版本自动，模块大小 5，生成二维码并保存图片至“提交资料\模块 C\题 3”目录下。

2. 在 NB-IOT 节点盒模块的液晶屏上显示上面生成的二维码图片，要求最终液晶屏显示的二维码高度不小于液晶屏 1/2 高度。

分析

• 液晶屏为64*128将图片设置为64 * 64
• 直接调用OLED_DrawBMP(32,0,64,64,bmp);
