This program is firmware to Home Automation Main module. Code for peripferal modules is stored in https://github.com/r-gal/LON_devices repository.
Compilation
General information: Project is prepared on IDE that uses GCC compiller, files from System directory may need be adapted to other compillers. Program is prepared to use on dedicated Hardware, Schematic and PCB layout in KiCad format is available in PCB directory. Program uses 3rd party software: CMSIS, HAL libraries and FreeRTOS, in Core directory files generated in STM32CubeMX tool are stored.
- Clone this repository with submodules
git clone https://github.com/r-gal/LON_v2 --recursive-
Create project in your IDE and attach all files from repository
-
Attach FreeRTOS Kernel files
git submodule add https://github.com/FreeRTOS/FreeRTOS-KernelUse source files from main directory and from correct portable. Choose correct port.c and portmacro.h files from portable directory - for STM32H725 and GCC compilator use portable\GCC\ARM_CM7\r0p1 Do not add any memory manager from portable/MemMang - Application offers own memory manager.
- Add preprocesor definitions:
USE_PWR_LDO_SUPPLY
USE_HAL_DRIVER

Questions
How big is the Lon6Main PCB?
It measures 100 × 100 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Lon6Main use?
288 parts, built around the STM32H725ZGT6, DM9161AEP, MCP6004-E/P and LM2596S-5.0. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lon6Main KiCad files?
From the r-gal/LON_v2 repository on GitHub, at the commit this page was made from: the board is PCB/Lon6Main.kicad_pcb and its schematic PCB/Lon6Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lon6Main design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
