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.
