micpython ili9342c驱动程序

对于使用MicroPython的ILI9342C驱动程序，你可以使用以下代码：

import time
import gc

ILI9342_DISPLAY_ON = const(0x29)
ILI9342_COLUMN_ADDR = const(0x2A)
ILI9342_PAGE_ADDR = const(0x2B)
ILI9342_MEMORY_WRITE = const(0x2C)

这个程序是一个Python的类，用于驱动ILI9342C显示器。它使用SPI接口与MicroPython设备通信，并允许您绘制像素和填充整个屏幕。你可以在代码中调用类的方法，例如`fill()`方法用于填充整个屏幕，`pixel()`方法用于在指定位置绘制像素，`show()`方法用于将缓冲区中的数据刷新到屏幕上。
