Description
我在使用RT-Thread Settings设置板上的SDA（P8.1)、SCL(P8.0)为软件I2C时，未能产生I2C时序，用万用表测1.3V左右，上拉电阻也无效。改用P5.6、P5.7时正常驱动I2C的SSD1306.

Research direction
Reproduce the software I2C setup in RT-Thread Settings using SDA P8.1 and SCL P8.0, then compare it with the working P5.6/P5.7 configuration and SSD1306 test. Trace the board pin configuration and software I2C entry points; done means valid I2C timing is produced on P8.1/P8.0 with the intended pull-ups.
