树莓派pico控制oled屏为什么会报错啊

Question

树莓派pico控制oled报错，以下为代码

from machine import Pin,I2C
from utime import sleep
from ssd1306 import SSD1306_I2C

WIDTH=128
HEIGHT=64,
sda=Pin(18)
scl=Pin(19)

i2c=I2C(0,sda=sda,scl=scl,freq=400000)
oled=SSD1306_I2C(WIDTH,HEIGHT, i2c)

oled.text('HELLO WORLD',0,0)
oled.show()

报错内容为bad SCL pin

Traceback (most recent call last):
  File "<stdin>", line 10, in <module>
ValueError: bad SCL pin

已经导入了ssd1306
连接方式如下

把i2c=I2C(0,sda=sda,scl=scl,freq=400000)这一句改为i2c=I2C(1,sda=sda,scl=scl,freq=400000)试试，你似乎硬件接的是I2C1
