Arduino for STM32

After some test i made it work! So my results: The sensor can be found with ID 0x76 ony when is connected to pins PB7---SDA and PB6---SCL I hsd to "set" the adddes to bme.begin() like bme.begin(0x76) Then the sensor work fine. This is my working code: #include <Wire.h> #include <SPI.h> #in...

I have this pin out diagram and i connect the sensor acording to this.
That's why i use PB6-PB9 pins , because as shown in the diagram is for SDA and SCL.
But no luck till now.
Anyway thanks for the help and usefull info.

Thanks Ray. I have used this with a M7N gps module and an TFT display with no problem. But i have problem with BME280 sensor. Is there any other library for BME280 to use or to do any modifications? Also i see that in your barometer project you use 15,16 pin in STM32 for SDA and SCL.That means that ...

You didn't answer the question: which core do you use? https://github.com/stm32duino/Arduino_Core_STM32 or https://github.com/rogerclarkmelbourne/Arduino_STM32 or other... If you don't provide enough information you will not be able to get help from the community. Sorry for this. I use https://gith...

I tried the scanner code from the above link.
It does not detect my BME280 sensor.
But when i connect an RTC module it finds it.
What am i doing wrong?
Any ideas?
My STM32 board is STM32F103C8T6

Hi to all I have an STM32F103 (blue pill) and i want to connect with a BME280 sensor in order to develop a project. I want to read temperature , humidity and pressure from the sensor. I use I2C protocol for my sensor. After some search i found that the sensor could connect to B8,B9 of the STM module...

Tried my sketch with M6N M7N and M8N.
Everything works fine.
I display the data in a 240X240 display.

Thanks for everything friend.

Friend Pito thanks for your help.
Suddenly the project works as it should.
I didn't change anything exept from removing the delay at "no gps data" (the first delay in my code)

Can you please sent the code for M7N?
I would like to test it.
