我是 python 的初学者，但想创建一个简单的硬件提醒来放置正确的 bin。也许在这个过程中学到一些东西。我的设置是 Pimoroni 的 Raspberry Pico 和 Pico-Unicorn 帽子。目标是每周四滚动提醒。首先我用单一颜色制作它，然后我想做一个特定的渐变
代码的要点是我使用了嵌套列表，其中列表的 [x][y] 对应于 pico-unicorn led 矩阵的 x 和 y。[x][y] 的值将是 0（熄灭）或十六进制颜色（以十六进制颜色点亮）。
缺少学习汇编，我可以用代码做什么？我的方法是否存在根本缺陷，或者只是 pico 很慢？它有效，不要误会我的意思，但如果我能做些什么来让它更好/更快——我只想学习最佳实践。另外，我研究过使用 framebuf 库，但它有一个我不喜欢的固定字体。感谢任何提示。
