| name | ss-new-driver |
| description | Scaffold a new Serial Studio I/O driver (a new data source under app/src/IO/Drivers/). Use when adding support for a new bus/transport — e.g. "add a <X> driver", "support reading from <Y>", "new data source". Encodes the canonical driver pattern and every registration touch-point so the new driver actually shows up in the UI, CLI, and connection manager. |

Serial Studio — new I/O driver
Before writing anything, read app/src/IO/Drivers/BluetoothLE.h and BluetoothLE.cpp in
full. They are the canonical reference for the driver contract — match their structure,
signal/slot wiring, and driverProperties() shape rather than inventing a new layout. After
the read, restate the driver contract in chat in 2-3 sentences (pure virtuals, publish path,
timestamp-at-boundary) before scaffolding — a contract you've just named is one the new code
follows, not one it drifts from (doc/claude/j-space.md).
A driver subclasses IO::HAL_Driver (app/src/IO/HAL_Driver.h) and must implement the pure
virtuals: close, isOpen, isReadable, isWritable, configurationOk, write, open,
driverProperties, and setDriverProperty. Also consider the non-pure virtuals with default
bodies — deviceIdentifier(), selectByIdentifier(), applyConnectionSettings() — which
drive device selection and reconnection. Received bytes are published via
publishReceivedData(...) — stamp the timestamp at the driver boundary (source owns time;
see [ss-hotpath]). Never re-stamp downstream.
Touch-points to wire (verify each against an existing driver)
app/src/IO/Drivers/<Name>.h / .cpp — the driver class, SPDX header, .h ordering rules.app/src/SerialStudio.h — add the value to the BusType enum (QML uses SerialStudio.BusType.*,
never integer literals).app/src/IO/ConnectionManager.{h,cpp} — accessor (e.g. network() / uart() analogue)
plus signal forwarding; the bus lookups live in ConnectionManager/DriverUiRegistry.cpp
(forBusType()) and the live-instance switch in ConnectionManager/DriverFactory.cpp
(DriverFactory::create(), spec 0070). Update both.app/CMakeLists.txt — add src/IO/Drivers/<Name>.cpp to the SOURCES list (sources are
listed explicitly, not globbed; commercial drivers go in the guarded
set(SOURCES ${SOURCES} ...) block).- QML configuration UI — the driver panes are bespoke forms (nothing renders
driverProperties() generically): create
app/qml/MainWindow/Panes/SetupPanes/Drivers/<Name>.qml, add its Loader to the
StackLayout in SetupPanes/Hardware.qml at the bus's enum position (the layout
indexes by Cpp_IO_Manager.busType), and register the new .qml in the QML_SOURCES list
in app/CMakeLists.txt.
app/src/API/EnumLabels.cpp — add the bus to the busTypeSlug() and busTypeLabel()
switches (the API's string names for the bus; commercial buses go inside the
#ifdef BUILD_COMMERCIAL block).app/src/DataModel/Project/ProjectEditorIcons.h — add the bus to the busTypeIcon()
switch, and app/src/DataModel/Project/ProjectEditorForms.cpp — add it to the busTypes
combobox list in the source form model.- Icon — add the driver SVG under
app/rcc/icons/devices/<tier>/ (16/24/32) and register it with a
<file> entry in app/rcc/rcc.qrc (busTypeIcon() returns its qrc:/ path).
- CLI (optional) — if it should be launchable headless, add options in
following the existing / pattern.
The list above drifts as the app grows. Before declaring done, grep a recently added bus value
(e.g. grep -rn "BusType::HidDevice" app/src) and mirror every switch/list it appears in.
Rules
- This is a multi-file change (>3 files): state the plan and get confirmation before executing.
- Follow
doc/claude/code-style.md (header ordering, [[nodiscard]], no in-header member init,
Q_EMIT not emit, Christmas-tree ordering).
- Run
python scripts/code-verify.py --check on the new files before handoff.
- Do not build or run the app — leave compilation and runtime testing to the developer.
