micropython esp8266+ssd1306(OLED) 显示中文(示例)

1.Adafruit_SSD1306

OLED显示库使用Adafruit_SSD1306:https://github.com/adafruit/Adafruit_SSD1306

连接示例:

库使用示例:

>>> from machine import Pin, I2C
>>> i2c = I2C(scl=Pin(5), sda=Pin(4))

>>> from ssd1306 import SSD1306_I2C
>>> oled = SSD1306_I2C(128, 64, i2c)

>>> oled.fill(1)
>>> oled.show()
>>> oled.fill(0)
>>> oled.show()


>>> oled.pixel(0, 0, 1)
>>> oled.show()
>>> oled.pixel(127, 63, 1)
>>> oled.show()

>>> oled.text('Hello', 0, 0)
>>> oled.text('World', 0, 10)
>>> oled.show()

>>> oled.invert(True)
>>> oled.invert(False)

2.显示中文

代码参考:https://github.com/TPYBoard/developmentBoard/tree/master/TPYBoard-v10x-master/

自己根据实际情况进行封装

显示中文函数:

#OLED=....
#fonts=....
def chinese(ch_str, x_axis, y_axis): 
   offset_ = 0 
   y_axis = y_axis*8  # 中文高度一行占8个  
   x_axis = (x_axis*16)  # 中文宽度占16个 
   for k in ch_str: 
       code = 0x00  # 将中文转成16进制编码 
       data_code = k.encode("utf-8") 
       code |= data_code[0] << 16 
       code |= data_code[1] << 8
       code |= data_code[2]
       byte_data = fonts[code]
       for y in range(0, 16):
           a_ = bin(byte_data[y]).replace('0b', '')
           while len(a_) < 8:
               a_ = '0'+a_
           b_ = bin(byte_data[y+16]).replace('0b', '')
           while len(b_) < 8:
               b_ = '0'+b_
           for x in range(0, 8):
               OLED.pixel(x_axis+offset_+x, y+y_axis, int(a_[x]))   
               OLED.pixel(x_axis+offset_+x+8, y+y_axis, int(b_[x]))   
       offset_ += 16

自模软件使用的是PCtoLCD2002

函数调用示例:

from machine import Pin, I2C
i2c = I2C(scl=Pin(5), sda=Pin(4))

from ssd1306 import SSD1306_I2C 
OLED= SSD1306_I2C(128, 64, i2c)
