Firmware
The firmware written in C++ is here.
Requirements for v1.0
- control stepper motor with Trinamic IC
- hall encoder connection to get current motor state
- read motor temperature
- CAN peripherie (dedicated PCB)
- power rails are secured by two fuses, with reverse polarity/overvoltage protection
- drive syncronous addressable LEDs
- get states from door and lock
- connection to two buttons to open/close door
- switch on/off Nerdstern (outdoor lamp)
Known issues in v1.0
- Mosfet Q1 has wrong connections for choosen part. Gate and Source are swapped.
- can be solved by simply solder the part upside down
- the LQFP32 package of STM32G0B1KE doesn't support HSE connection
- the internal HSI is used

Questions
How big is the StepperLockingSystem PCB?
It measures 54 × 84 mm and has 4 copper layers, 3.66 mm thick.
What parts does the StepperLockingSystem use?
107 parts, built around the STM32G0B1KET6, USBLC6-2SC6, 24LC64(LX) and TMC2209-LA. 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 StepperLockingSystem KiCad files?
From the netz39/Stepper-Locking-System repository on GitHub, at the commit this page was made from: the board is StepperLockingSystem.kicad_pcb and its schematic StepperLockingSystem.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StepperLockingSystem 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).
