Dynamic collaboration: tick calls log_loop_interval
Tick calls in apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp log_loop_interval in apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp.
How to read the diagram
- This Sequence Diagram focuses on the technical collaboration fragment of tick calling log_loop_interval.
- It describes a partial operation segment and is not necessarily equivalent to the complete business process.
- The current relationship comes from local call evidence; without Use Case Trace, it only represents a local collaboration fragment and is not directly equivalent to the main success scenario, callback, compensation or failure path.
Technical complexity analysis
- There is a calls relationship between apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp, and the technical boundary is apps/esp32_lvgl.
- Sequence Diagram is used to explain runtime or collaboration sequences, and is suitable for undertaking dynamic behaviors that are not clearly visible from the Package/Component diagram.
- If future evidence shows that there are asynchronous messages, callbacks, timeouts or failure compensation, multiple sequences should be broken out for the same business/technical scenario rather than crammed into one big picture.
Relationship with business complexity
- The main success path, failure path and callback path of the business Use Case will eventually fall on several technical sequence fragments.
- The current fragment may explain the technical execution steps in a certain business story; if there is no Use Case Trace, it only serves as a local collaboration fragment in the software structure model.
- If it is confirmed to belong to a Use Case, the project sequence document should be linked to the corresponding drill-down Sequence Diagram in docs/design.
Governance Suggestions
- Don't just judge the complete call chain based on a single relationship; you need to combine the upstream and downstream relationships to complete the scenario.
- When the sequence involves external systems, model calls, file writing, or Git operations, failure paths and retry/compensation instructions should be added.
- If the sequence supports user-visible functions, the business drill-down diagram of the organization/process model should be maintained simultaneously.

Drill-down of semantic elements in the diagram
-
tick
component
tick is the source participant of the current Sequence Diagram, used to explain the tick calls in apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp log_loop_interval in apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp.
- Technical role
- Message originator/relying party: It triggers or references the target capability.
- Why it appears
- Local repository evidence calls were observed between apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp, so the tick was put into sequence.
- Relationship meaning
- tick -> log_loop_interval indicates the dependency direction of the current fragment; if the relationship is only import, it can only indicate static dependencies and cannot directly prove the runtime order.
- Drill-down intention
- Drill-down tick can view the corresponding Component Diagram or structural context to determine the responsibilities of this participant within the larger technical boundary.
- Business association
- The execution process of the business Use Case may fall on multiple sequence fragments; the current fragment is only a candidate technical step and requires organizational/process model evidence to confirm the business meaning.
- Impact of change
- Modifying apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp may change the sequence's dependencies, calling evidence, and interpretation of related component/structure diagrams.

- Official module: apps/esp32_lvgl
Risk
- A single sequence fragment is not enough to prove the complete call chain or the successful path of the business owner.
Problem
- The current relationship type needs to be distinguished by evidence between runtime calls, static imports, type references, or configuration references; if it is only a static relationship, this diagram should not be interpreted as a real calling sequence.
-
log_loop_interval
component
log_loop_interval is the target actor of the current Sequence Diagram and is used to interpret tick calls log_loop_interval in apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp.
- Technical role
- Message receiving/relying party: It provides the ability to be referenced or called by the current fragment.
- Why it appears
- Local repository evidence calls were observed between apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp and apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp, so log_loop_interval was put into sequence.
- Relationship meaning
- tick -> log_loop_interval indicates that the target capability is dependent on the current fragment; it needs to be combined with the call evidence to confirm whether it is a runtime call, a type reference or a static import.
- Drill-down intention
- Drilling down log_loop_interval can view the corresponding Component Diagram or structural context to determine the responsibilities of this participant in the larger technical boundary.
- Business association
- The execution process of the business Use Case may fall on multiple sequence fragments; the current fragment is only a candidate technical step and requires organizational/process model evidence to confirm the business meaning.
- Impact of change
- Modifying apps/esp32_lvgl/src/esp32_lvgl_arduino_loop_runtime.cpp may change the sequence's dependencies, calling evidence, and interpretation of related component/structure diagrams.
