=================

Micropython module for Sensirion SPS-30, based on Sensirion official C driver packaged as mpy file.

Installation

-

...

Development

-

Install toolchain:

* Pull the needed submodules: `git submodule init` and pull the submodules to commit/release compatible with your architecture

  * Eg. pull micropython 1.20.0 if you want to run the .mpy on micropython 1.20.0

* Install prerequisites:

    `sudo apt install git wget flex bison gperf python3 python3-pip python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0`

* Install **gcc-multilib** if you want to cross-compile:

    `sudo apt install gcc-multilib`

* Install **ESP-IDF toolchain**: 

    `.toolchain/esp-idf/install.sh esp32`

Compile native C module (.mpy file):

* `. toolchain/esp-idf/export.sh`

* Build the **.mpy file**: `make`, or eg. `make ARCH=x86` if you want to cross compile
