Hello,

this is the first time i'm writing an issue on Github.

Well, i'm using your library with STM32duino and a "Blue Pill" STM32F103C8 - It's working fine out of the box!
I just set the I2C clock speed to 100kHz and added a small ceramic capacitor (0.1 µF) between GND and VCC near the sensor.

Maybe you can add this MCU to the list of supported ones.

Best regards,

Hello Sir I was not able how to install the libary at Platform IO maybe you are able to help me.

Hello Maarten,

The examples show a function being called to setup Wire:

Wire.begin(/*SDA*/D2,/*SCL*/D1);

When using this library in PlatformIO with the Arduino framework I had to set SDA and SCL separately:

Wire.setSDA(SDA);
Wire.setSCL(SCL);
Wire.begin();

Based on current Arduino documentation, they might've changed Wire's 'begin' function to only accept an address rather than set SDA and SCL pins.

After this change is made, the code successfully runs on an STM32L031K6 microcontroller.

Hi Maarten!! just read IAQ-core P datasheet from AMS ans they talk about use 4k7 Ohms resistors with SDA / SCL and VCC.
I want to mount one IAQ and would know if u use the resistors berfore mountig.
Resistors are not in your wiring and i'm not sure if ther are necesary or not.

Regards
