This repository contains the embedded driver sources for Sensirion's SFM product line.

DOWNLOAD THE RELEASE ZIP FROM THE RELEASE PAGE

Clone this repository

 git clone --recursive https://github.com/Sensirion/embedded-sfm.git

Repository content

  • embedded-common (submodule repository for the common embedded driver HAL)
  • sfm3003 (SFM3003 driver)
  • sfm3019 (SFM3019 driver)
  • sfm-common (functionality common across SFM sensors)

Collecting resources

make release

This will create the release folder with the necessary driver files in it, including a Makefile. That way, you have just one folder with all the sources ready to build your driver for your platform. You can find a pre-built release package on the release page linked at the top of this document.

Files to adjust (from embedded-common)

You only need to touch the following files:

  • sensirion_arch_config.h (architecture specifics, you need to specify the integer sizes)

and depending on your i2c implementation either of the following:

  • embedded-common/hw_i2c/sensirion_hw_i2c_implementation.c functions for hardware i2c communication if your platform supports that
  • embedded-common/sw_i2c/sensirion_sw_i2c_implementation.c functions for software i2c communication via GPIOs

Building the driver

  1. Adjust sensirion_arch_config.h if you don't have the <stdint.h> header file available
  2. Implement necessary functions in one of the *_implementation.c files described above
  3. make

Please check the embedded-common repository for further information and sample implementations.
