【雕爷学编程】MicroPython动手做（16）—

知识点：什么是掌控板？
掌控板是一块普及STEAM创客教育、人工智能教育、机器人编程教育的开源智能硬件。它集成ESP-32高性能双核芯片，支持WiFi和蓝牙双模通信，可作为物联网节点，实现物联网应用。同时掌控板上集成了OLED显示屏、RGB灯、加速度计、麦克风、光线传感器、蜂鸣器、按键开关、触摸开关、金手指外部拓展接口，支持图形化及MicroPython代码编程，可实现智能机器人、创客智造作品等智能控制类应用。

4、OLED显示外部图片
OLED屏幕只能显示颜色深度为1或者就是黑白模式的bmp格式，可以使用Photoshop、“画图”或者其他图片显示软件进行转换。转换好格式的图片需要使用取模工具对图片进行取模，转换的图片大小应该为128*64，也就是掌控板屏幕的大小。所选的图片线条要分明，且颜色不能太过丰富。
（1）选择一张图片

在这里插入图片描述
用在线PS打开图片，这里使用 https://www.uupoop.com/

（3）调整为128*64规格，另存为bmp格式

（4）安装小图片取模工具Image2Lcd

（6）将复制的16进制图像数据粘贴在下列指令的空格处。

描述：OLED绘制16进制数组图像。将16进制数据转换成图像显示在oled屏幕的指定位置处。尝试将程序搭建好，将图片显示出来。
