OLED显示库使用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)
代码参考:
自己根据实际情况进行封装
显示中文函数:
