硬件要求 6 | 7 | 1. 运行`micropython`的开发板，且`micropython>=1.17` 8 | 2. 使用`SSD1306`驱动芯片的`OLED屏幕`或者是`ST7735`驱动芯片的`LCD`屏幕亦或是`1.54英寸的e-Paper` 9 | (只要是使用`FrameBuffer`的屏幕都支持，但本项目提供的驱动只有这三种) 10 | 3. 如果想要在`OLED`或者`e-Paper`上使用`ufont`显示支持`GB2312`的所有字符，则至少 `230Kbyte` 的空闲 ROM 空间和 `20 Kbyte`的空闲内存 11 | 如果想要在`ST7735`上使用`ufont`显示支持`GB2312`的所有字符，则至少 `230Kbyte` 的空闲 ROM 空间和 `100 Kbyte`的空闲内存 12 | 13 | ## 快速上手 14 | 15 | 1. 准备运行`micropython`的开发板和一个`SSD1306`的`OLED`屏幕，并完成连接 16 | 17 | 2. 将`demo/ssd1306_demo.py`用编辑器打开 18 | 19 | ```python 20 | # 修改为对应的 Pin 21 | i2c = I2C(scl=Pin(2), sda=Pin(3)) # Line 29 22 | ``` 23 | 24 | 3. 依次将`demo/ssd1306_demo.py`、`driver/ssd1306.py`、`ufont.py`、`unifont-14-12917-16.v3.bmf`上传到**开发板根目录**，运行`ssd1306_demo.py`即可 25 | 26 | ## 使用方法 27 | 28 | 仅需三步就能使用`ufont`: 29 | 30 | ```python 31 | # 第一步：导入 ufont 库 32 | import ufont 33 | ··· 34 | # 第二步：加载字体 35 | font = ufont.BMFont("unifont-14-12917-16.v3.bmf") 36 | ··· 37 | # 第三步：显示文字 38 | font.text(display, "你好", 48, 16, show=True) 39 | ``` 40 | 41 | ### 详细参数 42 | 43 | ```python 44 | text(display, # 显示对象 45 | string: str, # 显示文字 46 | x: int, # 字符串左上角 x 轴 47 | y: int, # 字符串左上角 y 轴 48 | color: int = 0xFFFF, # 字体颜色(RGB565) 49 | bg_color: int = 0, # 字体背景颜色(RGB565) 50 | font_size: int = None, # 字号大小 51 | half_char: bool = True, # 半宽显示 ASCII 字符 52 | auto_wrap: bool = False, # 自动换行 53 | show: bool = True, # 实时显示 54 | clear: bool = False, # 清除之前显示内容 55 | alpha_color: bool = 0, # 透明色(RGB565) 当颜色与 alpha_color 相同时则透明 56 | reverse: bool = False, # 逆置(MONO) 57 | color_type: int = -1, # 色彩模式 0:MONO 1:RGB565 58 | line_spacing: int = 0, # 行间距 59 | **kwargs) 60 | ``` 61 | 62 | 63 | 64 | ##

-------------------------------------------------------------------------------- 1 | ## MicroPython 中文字库[ufont]的使用 2 | 3 | Github: https://github.com/AntonVanke/MicroPython-Chinese-Font 4 | 5 | #### 使用方法 6 | 7 | 以【合宙 Air10x 系列屏幕扩展板驱动】为例 8 | 9 | 1. 如何确认驱动是否支持？ 10 | 11 | ```python 12 | from st7735 import ST7735 13 | from framebuf import FrameBuffer 14 | print(issubclass(ST7735, FrameBuffer)) # True: 支持;False: 不支持 15 | ``` 16 | 17 | 如果返回的是`True`则支持，`False`的话需要一些额外的操作 18 | 19 | 2. 先初始化屏幕 20 | 21 | ```python 22 | from machine import SPI, Pin 23 | from st7735 import ST7735, color 24 | spi = SPI(1, 30000000, sck=Pin(2), mosi=Pin(3)) 25 | display = ST7735(spi=spi, cs=18, dc=12, rst=1, bl=19, width=160, height=80, rotate=1) 26 | ``` 27 | 28 | 3. 载入字体 29 | 30 | - 上传`ufont.py`、`unifont-14-12888-16.v3.bmf`到开发板 31 | 32 | ```python 33 | import ufont 34 | f = ufont.BMFont("../unifont-14-12888-16.v3.bmf") 35 | ``` 36 | 37 | 4. 测试字体 38 | 39 | 1. 基本使用 40 | 41 | - `text(显示实例，文字，x轴，y轴，颜色 )` 42 | 43 | - `show = True` 立即显示，就不需要执行 `display.show() ` 44 | 45 | ```python 46 | f.text(display, "你好", 0, 0, color=0xf8, show=True) 47 | ``` 48 | 49 | 2. 如何设置字号 50 | 51 | ```python 52 | f.text(display, "你好", 32, 0, color=0xe007, font_size=18, show=True) 53 | ``` 54 | 55 | 3. 如何显示反转背景的字体 56 | 57 | ```python 58 | f.text(display, "你好", 68, 0, color=0xe007, reverse=True, show=True) 59 | ``` 60 | 61 | 4. 如何显示的时候清除之前的内容 62 | 63 | ```python 64 | f.text(display, "你好\nabCD123", 0, 0,font_size=16, color=0xf8, clear=True, show=True) 65 | ``` 66 | 67 | 5. 当某些字体需要全格显示时 68 | 69 | - `half_char=False` 英文数字全格显示 70 | 71 | ```python 72 | f2 = ufont.BMFont("DIGITAL-Dreamfat-95-16.v3.bmf") # 载入特殊字体 73 | f2.text(display, "abCD123", 0, 32,font_size=16, color=0xe007,half_char=False,show=True) 74 | ``` -------------------------------------------------------------------------------- /doc/如何生成点阵字体文件.md:
