BMX280 for ESP-IDF

BMX280 is a basic I2C based driver for ESP32 devices licensed mostly under MIT. (See caption "License" for details.)

Usage

Clone this repository or add it as a submodule into your components directory. Add the module as a requirement to your main module, or other modules.

Example Code

To use the legacy i2c.h driver, please refer to the example_with_i2c.h.

To use the i2c_master.h driver (ESP-IDF >= 5.3):

• First, run idf.py menuconfig to configure the project.

• Navigate to Component Config -> BMX280 Options -> I2C driver setting -> I2C Master Driver (i2c_master.h).

• Press the 'S' key to save the configuration.

• You can then use the I2C Master driver to complete your code.

For example code, please see the example_with_i2c_master.h.

Note: If you want to use the legacy i2c.h driver, no changes are needed; continue using bmx280_create to create the anonymous structure bmx280. If you use the i2c_master.h driver, you need to use bmx280_create_master to create the structure.

License

This repository contains a lot of code I have written which is licensed under MIT, however there are sections modified from the BME280 datasheet which is unclearly licensed.

The unclearly licensed section is clearly marked with two comments. Any code between // HERE BE DRAGONS and // END OF DRAGONS contains modified versions of the Bosch Sensortec code.

Please take note of this in production.
