传感器实验——LCD中文显示
字体之前弄过，就不赘述了。只看如何使用即可
LCD显示小车状态
MR开发板
1.54寸液晶屏st7789 spi
基本用法
| 属性 | 说明 |
|---|---|
| lcdinit() | 初始化 |
| draw_cn(text,x,y,a) | 字号：16px…text：文字。x：x坐标。y：y坐标。a：间距 |
| draw_zh20_str(text,x,y,a) | 字号：20px…text：文字。x：x坐标。y：y坐标。a：间距 |
| set_color(color565(R,G,B),color565(R,G,B)) | 前景色，背景色RGB模式 |
