Arduino for STM32

The hardware I2C is tested OK,but the software I2C is also failed.

Well, my I2C bus has some devices that can't be set address in their init functions. At the same time,U8g2Lib also provides the SW init function,so I want to use the software I2C to use the OLED .

Hello guys,
I tried to use the 128X64 OLED by using U8g2Lib's software I2C , but it doesn't work.
However, I used the same code on Arduino UNO,and it worked well (except pins definations).
My chip is STM32F103ZET6
SDA => PF8
SCL => PF10
Please recommand me a usable lib if this actually a bug.
