![]() Inside the main.c file, make sure the following code is part of your script by including the lines of code given below. Now let us look at our main.c file that was generated. STM32 Blue Pill BME280 Sensor Code STM32CubeIDE Head over to Core > Src and create a new file called ā fonts.cā Copy the following code from this link and save it to this file. Although there are several different versions of BME280 available in the market, the one we will be studying uses the I2C communication protocol. This sensor uses I2C or SPI to communicate data with the microcontrollers. It is mostly used in web and mobile applications where low power consumption is key. The BME280 sensor is used to measure readings regarding ambient temperature, barometric pressure, and relative humidity. BME280 with ESP32 ā Display Values on OLED ( Arduino IDE).BME280 with ESP8266 NodeMCU ā Display Values on OLED ( Arduino IDE).BME280 with Arduino: Display Readings on OLED ( Arduino IDE).BME280 with Raspberry Pi Pico using MicroPython.We have similar guides for BME280 with other microcontrollers: For demonstration, we will connect an SSD1306 OLED with the STM32 Blue Pill to view the sensor data on the OLED. At first, we will briefly introduce you to BME280 sensor, then interface it with our STM32 and program it for temperature, pressure, and humidity measurement using STMCube IDE. In this tutorial, we will learn how to interface BME280 sensor with STM32 Blue Pill and program it in STM32CubeIDE using HAL libraries. ![]()
