| - | ## MicroGUI based DDS | + | ## 基于MicroPython的Micro-GUI |
| + | 来自[[https://github.com/peterhinch/micropython-micro-gui|Peter Hinch在Github上的项目分享]] | ||
| + | 它是一个轻量级的、可移植的MicroPython GUI库，用于显示，并从framebuf子类化了驱动程序。它是用Python编写的，可以在标准的MicroPython固件构建下运行。输入资料的选项包括: | ||
| + | - 根据应用程序，通过2到5个按钮。 | ||
| + | - 通过一个开关导航操纵杆。 | ||
| + | - 通过两个按钮和一个像这样的旋转编码器。 | ||
| + | |||
| + | 由于对输入的支持，它比nano-gui更大、更复杂。它可以在屏幕之间切换和启动模态窗口。除了nano-gui小部件外，它还支持列表框、下拉列表、各种输入或显示浮点值的方法以及其他小部件。 | ||
| + | 它与nano-gui的所有显示驱动程序兼容，因此可移植到各种显示器上。它还可以在主机之间移植。 | ||
