• A display library for Micropython: high versatility, multifunctionality, implemented purely in Micropython.
• This README may contain translations that are not entirely accurate.

The following are the display effects of version 2.0.

• Ability to display non-ASCII characters, such as Chinese and special symbols, by importing bmf font files.
• Supports displaying PBM images in P4/P6 format and BMP images in 24-bit.
• Default parameters can be set during initialization, making function calls more concise. Additionally, the current function call can override the default parameters.
• Compatible with most official and unofficial versions of MicroPython. It is implemented purely with native MicroPython and does not require firmware compilation. Additionally, it maintains high efficiency as much as possible.
• Supports multiple screen models such as SSD1306, ST7735, and ST7789. It also supports driving high-resolution screens on low-memory development boards (e.g., ESP32C3 driving 240*240 ST7789 screens).

• Please refer to the source code comments.（The comments section is written in Chinese and may need translation in order to read.）

For images in the dat format, make sure that they do not exceed the screen display area when using non-framebuffer driver modes. Otherwise, the image may not be displayed correctly.

# 这是一个使用示例 This is an example of usage
import time
from machine import SPI, Pin
from driver import st7735_buf
from lib.easydisplay import EasyDisplay

# ESP32S3 & ST7735
spi = SPI(1, baudrate=20000000, polarity=0, phase=0, sck=Pin(18), mosi=Pin(17))
dp = st7735_buf.ST7735(width=128, height=128, spi=spi, cs=14, dc=15, res=16, rotate=1, bl=13, invert=False, rgb=False)
ed = EasyDisplay(dp, "RGB565", font="/text_lite_16px_2312.v3.bmf", show=True, color=0xFFFF, clear=True)

ed.bmp("/img/test.bmp", 0, 0)
time.sleep(3)
ed.pbm("/img/test.pbm", 0, 0)
time.sleep(3)
ed.text("你好，世界！\nHello World!\nこんにちは、世界！", 0, 0)
