Lightweight, non-blocking C libraries for STM32, and five installers that put any library into an STM32, Zephyr, ESP-IDF, Arduino or PlatformIO project with one command.
$ pip install stm32-installer $ stm32-installer nimaltd/stm32-installer-example Fetching nimaltd/stm32-installer-example ... Files written example/src/example.h written example/src/example_config.h written example/src/example.c Project updated CMake Added example to CMakeLists.txt Done. #include "example.h" and you are away.
Each installer copies the library into your project, adds it to the build, brings what it needs, and keeps your settings through every update.
For STM32 projects in CMake, STM32CubeIDE, Keil, IAR and Makefile.
$ pip install stm32-installer $ stm32-installer nimaltd/stm32-installer-example
The example blinks an LED without HAL_Delay(), in any STM32 project.
For Zephyr and nRF Connect SDK applications.
CMakeLists.txt and switches it on in prj.conf$ pip install zephyr-installer $ zephyr-installer nimaltd/zephyr-installer-example
The example builds in any Zephyr application, native_sim included.
For ESP-IDF projects, on any ESP32 chip.
components/, with its own CMakeLists.txtidf.py menuconfigsdkconfig.defaults$ pip install esp32-installer $ esp32-installer nimaltd/esp32-installer-example
The example is a period that never blocks, with its settings in menuconfig.
For the Arduino IDE, version 1 or 2, and arduino-cli.
src folder, for that sketch alonelibrary.properties Arduino knows the library by$ pip install arduino-installer $ arduino-installer nimaltd/arduino-installer-example
The example builds for any board, and prints on Serial.
For PlatformIO, with any framework: Arduino, ESP-IDF, STM32Cube, or none at all on the native platform.
lib/, with the library.json PlatformIO builds it byplatformio.ini, for every environment$ pip install pio-installer $ pio-installer nimaltd/pio-installer-example
The example builds with every framework, and runs on your computer with no board.
USER CODE lines survives every update. Anything else of yours is saved as a .bak.--uninstall takes the files and the project changes back out.Ready for stm32-installer, each with one command. The rest are moving over one by one.
Driver for SPI NOR flash, W25Qxx and compatible, on the STM32 HAL.
stm32-installer nimaltd/spifDriver for 24xx I2C EEPROMs, 24C01 to 24C512, on the STM32 HAL.
stm32-installer nimaltd/ee24Non blocking state sequencer and interrupt task queue for STM32, with no RTOS.
stm32-installer nimaltd/seqOS abstraction layer for STM32: the same mutex and delay on bare metal, FreeRTOS and ThreadX.
stm32-installer nimaltd/osalLittleFS by the littlefs project, a fail-safe file system, ready for stm32-installer.
stm32-installer nimaltd/littlefsAny library with an installer.yml installs the same way, on all five platforms.
The installers are not only for my libraries. Put one installer.yml at the root of any library's repository, and all five can install it: each reads its own keys and leaves the others alone.
Only name and files are required. Everything else, the libraries it needs, its options, its settings and each platform's own keys, is there when you want it.
The keys, platform by platform:
name: mylib description: Driver for the X chip repository: https://github.com/you/mylib license: Apache-2.0 files: headers: - src/mylib.h - src/mylib_config.h # your settings sources: - src/mylib.c
Electronics engineer and embedded developer. More than 20 years of C for STM32 microcontrollers, across embedded programming, electronics design and hardware testing, and most of it spent on one goal: libraries that are actually easy to use.
Every library and installer here is free. If one saved you an afternoon, a star helps other engineers find it, and a coffee keeps them coming.
