micropython-sps30

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
