Embedded-SGP30-7.1.2，Sensirion官方驱动程序，2021年5月版本

# Arduino Specific README This guide contains some hints on getting the generic reference drivers working on Arduino platforms. Note that this is a generic driver meant to be adaptable to any platform with minimal effort but it is not, by design, a ready-to-use Arduino driver. Kindly keep in mind that Sensirion cannot assist with general Arduino questions not related to the driver. ## Project Setup Arduino compiles all files in a Library (See [Build-Process](https://github.com/arduino/Arduino/wiki/Build-Process)). Thus, for Arduino to pick up the driver as a library all files must be in a directory with the name of that library and it must be in the folder where your Arduino IDE installs libraries. For the sake of this tutorial we'll call this the `sxx30` folder, where _sxx_ is substituted for the actual project name (name of your _.ino_ file). We suggest using the driver's name as project name e.g. _sgp30_, _sps30_, _shtc1_ etc. ### Files to copy to your Library folder Use as base the *release* version of your driver from `make release` or, if you're not sure what this means, download the release Zip from the driver's releases page on GitHub, e.g. for the embedded-sgp driver download _sgp30-x.y.z.zip_ from [https://github.com/Sensirion/embedded-sgp/releases](https://github.com/Sensirion/embedded-sgp/releases) * Copy all content except the example usage file (`example_usage.c` or `sxx30_example_usage.c`) from the release folder into the `sxx30` library folder. * Copy the Arduino sample implementation `sensirion_hw_i2c_implementation.cpp` from this folder into the `sxx30` library folder. ### A Typical Example Project ```cpp #include <Arduino.h> #include "sxx30.h" /* Adapt for your sensor */ void setup() { /* // Initialize Serial for debugging Serial.begin(115200); while (!Serial) { delay(100); } */ } void loop() { // adapt the code from the main() method content from sxx30_example_usage.c // make sure to replace any sleep(x) calls with delay(x * 1000) } ``` ### sensirion\_arch\_config.h Copy the `sensirion_arch_config.h` from this folder to your `sxx30` folder. Note that it may need additional tweaks according to your specific arduino platform. If needed, you should ask for help on an Arduino forum for your specific platform as Sensirion is not in a position to help you with such questions. ### Board-Specific Setup Let us know if your Arduino needs a tweak and we'll be happy to document your changes here. ## Common Compile Errors This section lists some of the most common compile errors encountered along with possible solutions. If your error does not appear in this list, your error is likely not related to the driver and you should ask for help on an Arduino forum for your specific platform as Sensirion is not in a position to help you with such questions. ### Sleep was not declared in this scope Delete the example usage file or replace `sleep(x)` with `delay(x * 1000)` Multiply by 1000 because delay uses milliseconds but sleep uses seconds. error: 'sleep' was not declared in this scope ## Hardware ### Limited Receive Buffer Arduino's Wire library has a limited receive buffer of 30bytes, which is not enough for the SPS30. We're offering an alternative I2C implementation for our drivers to address this, called arduino-alt-i2c. Another possible workaround is using a software-i2c implementation. See [embedded-sps #7](https://github.com/Sensirion/embedded-sps/issues/7) for more details.
