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

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 sin...
