我是编码新手。我有一个想要完成的项目，所以这令人生畏。我让别人写了这个，但我的 LCD 是 DOA，所以我想切换到 OLED。谁能帮我把这段代码从 LCD 显示器转录到 OLED？我想我取得了一些进展，但我不完全确定下一步该做什么。我已经设置了头文件以导入 OLED 的 SSD1306 python 文件，并将 I2C 的选项更改为 OLED 显示器的设置。我已经设置了引脚，并且我已经更改了 I2C 运行到我认为适合此 OLED 显示器时发生的情况，但我不确定。后来有一些代码可以控制写入显示器的内容，但这是我无法理解的地方。我不知道在 lcd_print 的东西上要改变什么才能让它做同样的事情，但是在 OLED 上......

from machine import I2C, Pin

import sys


relay_pin = 6
relay = Pin(relay_pin, Pin.OUT)

i2c = I2C(0, sda=Pin(0), scl=Pin(1))
def lcd_print(keyword):
  if keyword is not str:
    keyword=str(keyword)
  I2C_ADDR     = 0x3c


  i2c = I2C(0, sda=Pin(0), scl=Pin(1))
  lcd = ssd1306.SSD1306_I2C(128, 32, i2c)
  lcd.text(keyword)
  lcd.show()
