Arduino for STM32

I changed the pin to SCL -> PB10 and SDA->pB11 and i got this !! false measurment !!

I try with this .. it gives me the adresse of mlx90614 which is 0x5A !!

Hi friend,
actually, i am working on the same project.
I would interface the gps neo 6m with stm32 bluepill.
I programme with Arduino ide.
my one code doesn't work . Can you share yours. I hope that it will work.
Thank you.
I really need it because i ma blocked !!!

Hi to all community,

I have an STM32F103 (blue pill) and i want to connect with a mix90614 temperature sensor in order to develop a project for my internship.
I want to read temperature, from the sensor.
I use I2C protocol for my sensor (B8---SDA , B9---SCL)
I used Adafruit mlx90614 library.
But ...
