显示英文字符

import ssd1306py as lcd


lcd.init_i2c(22, 21, 128, 64)
lcd.text('font8x8', 0, 0, 8)
lcd.text('font16x16', 0, 20, 16)
lcd.show()

显示汉字

汉字字库较大,单一字号的字库就需要几M字节,所以没有放在库中。需要自己将需要显示的汉字做成字库传入到库中。

制作字库可以使用工具PCtoLCD2002,百度网盘下载链接,提取码:z4tf

使用方法可参考:如何使用PCtoLCD2002取模(汉字、ASCII字符集)

提取的汉字字库做成字典格式供程序使用,字典的键是汉字的utf-8编码值。可以使用python获取python的utf-8值,比如: 在这里插入图片描述 则汉字”你“的utf-8值是0xe4bda0。

也可以使用在线转换工具查询:http://www.mytju.com/classcode/tools/encode_utf8.asp

比如以下示例,显示汉字“你好”。
