drawing and writing

There are two ways, the second is recommended

First, use the lcd module to draw directly on the screen

import image, lcd

lcd.init()

lcd.draw_string(0, 0, "hello")

For more functions and parameters, please refer to lcd API Manual

Second, use the image module to draw in the memory, and use the lcd.display function to display the entire picture on the screen after drawing

import image, lcd

lcd.init()

img = image.Image(size=(320, 240))
img.draw_string(0,0, "hello")
lcd.display(img)

For more functions and parameters, please see image API manual, search for image.draw on the page to find all drawing functions
For Chinese (multi-language) support, please see How to display Chinese, or search for "font".
