This repository contains the embedded driver sources for Sensirion's SGP product line.
Download the latest ready-to-use driver bundle from the releases page
We strongly recommend to use the driver from the release bundle instead of cloning the repository.
Note: If you use the SVM40 module (which contains an SGP40) please check out https://github.com/Sensirion/embedded-svm40.
Note: If you are using SGP40 or SGP41 sensor, please check out the following repositories:
git clone --recursive https://github.com/Sensirion/embedded-sgp.git
- embedded-common - Submodule repository for common embedded driver stuff
- embedded-sht - Submodule repository for SHT drivers
- sgp40 - SPG40 driver
- sgp40_voc_index - Driver for a SGP40 and SHTC3 combo with a VOC algorithm.
- sgp30 - SGP30 driver
- sgpc3 - SGPC3 driver
- svm30 - Driver for the SVM30 module consisting of a SPG30 and an SHTC3 sensor.
- sgpc3_with_shtc1 - Driver for a SGPC3 and SHTC1 sensor combo.
- sgp-common - Common code for all SGP drivers.
make release
This will create a 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 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 one of the following:
sensirion_hw_i2c_implementation.c(functions for hardware i2c communication if your platform supports that)sensirion_sw_i2c_implementation.c(functions for software i2c communication via GPIOs)
- Step into your desired directory (e.g.: release/sgp30)
- Adjust sensirion_arch_config.h if you don't have the
<stdint.h>header file available - Implement necessary functions in one of the
*_implementation.cfiles - make
Please check the embedded-common repository for further information and sample implementations.
