The code needed to build a mechanical 7-segment display that uses electromagnets to display characters

Repo for various embedded projects my husband and I are working on together
Kitty feeder is an open-source printed circuit board by aladshaw3, from the aladshaw3/embedded_projects repository on GitHub, published under the MIT licence. It is a 2-layer board of 64.4 × 33.4 mm with 10 parts on 60 nets.
It is built around the LD1117V33. Its parts include 4 resistors and 1 IC.
Mono Repo for various personal embedded projects with my husband
This mono repo is strictly just for code development with a lot of boilerplate for helping to write unit tests for the code. Does not include build instructions for specific devices.
(1) Initial Setup
make environment
make grab-submodulesNOTE: Not strictly required if you have an environment that is already setup. See build/setup.sh for recommendations
(2) Running unit tests
make unit-testsor
make unit-test TEST={TEST_NAME}(3) Checking formatting
make static-code-analysis
make lint-filename
make pre-commitor
make all-checks(3) Building API-Docs
make api-docsprojects folder(1) Start by creating new folder under projects
e.g.,
embedded_projects/
├── projects/
│ ├── ExampleProject/
│ └── NewProject/ # Add here(2) Update the projects/sources.cmake and include.cmake files for new location
e.g., source.cmake
################# Add other project directories here #####################
include_sources(ExampleProject)
include_sources(NewProject) # Add heree.g., include.cmake
################# Add other project directories here #####################
include_directories(${SIL_DIR}/ExampleProject)
include_directories(${SIL_DIR}/NewProject)(3) Adding subdirectories in your project
You can add any subdirectories to your new project folder. You will
then need to add another layer of a sources.cmake file to add the
new subdirectories to be discoverable by the unit testing and static
code analysis infrastructure
See projects/ExampleProject for an example.
(4) Adding source code
Each sub-folder should contain both the header file and source file together.
Each sub-folder that contains source files needs to also include a sources.cmake
file. This file should call an add_sources helper function to tell cmake what
source files to include in the builds.
e.g., projects/ExampleProject/unit_tests/sources.cmake
add_sources(test_builds.cpp)
add_sources(test_eigen.cpp)| Qty | Value | Footprint | References |
|---|---|---|---|
| 4 | R | Resistor_THT:R_Axial_DIN0207_L6.3mm_D2.5mm_P5.08mm_Vertical | R1, R2, R5, R6 |
| 2 | Conn_02x04_Odd_Even | Connector_PinHeader_2.54mm:PinHeader_2x04_P2.54mm_Vertical | FeederIn1, FeederMicro1 |
| 2 | ~ | cat_feeder_footprints:nau7802_module | INA228, U2 |
| 1 | Adafruit_Feather_Generic | Module:Adafruit_Feather | A1 |
| 1 | LD1117V33 | Package_TO_SOT_THT:TO-220-3_Vertical | U1 |
It measures 64.4 × 33.4 mm and has 2 copper layers, 1.6 mm thick.
10 parts, built around the LD1117V33. 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.
From the aladshaw3/embedded_projects repository on GitHub, at the commit this page was made from: the board is projects/cat_feeder/pcb/kitty_feeder.kicad_pcb and its schematic projects/cat_feeder/pcb/kitty_feeder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
