RP2040-2x GC9A01显示在共享SPI显示位图眼睛和绘制眼睛绘制仪表使用多语言和符号字体
这个使用RP2040-Zero和两个GC9A01显示器的演示项目侧重于向每个屏幕发送不同的图像。通过利用SPI端口的共享使用，两个显示器都连接到RP2040-Zero，允许有效的通信。建立连接后，使用适当的代码将不同的数据发送到每个屏幕。这允许您在一个屏幕上显示时间和日期信息，同时在另一个屏幕上显示彩色图形或动画。这个项目是一个令人印象深刻的例子，突出了RP2040-Zero的灵活性和功能，以及使用共享SPI端口的效率。
使用Ardunio_GFX_Library绘制眼部图形
绘制Gauge样本(Ms CoPilot帮助完成)
下一步尝试显示空格字符，天气符号和土耳其字符。
