This tool automates the creation of a compliant EtherCAT slave stack skeleton for embedded hardware. It is designed for firmware engineers, system integrators, and automation developers building devices that participate in EtherCAT networks, such as drives, I/O blocks, or safety peripherals. The problem solved is delivering a consistent, IEC 61158-conformant code scaffold for stack version 1.5.3, reducing setup time and enabling rapid bring-up and validation in hardware-requirements scenarios. It complements existing toolchains by producing portable templates and wiring diagrams that integrate with common IDEs and compilers.\n\nCore Logic & Features: The tool analyzes hardware constraints (target MCU/SoC, clock frequency, RAM/ROM budget, memory map) and project goals (process data size, endianness, distributed clocks preference) to emit a code package with a minimal yet compliant stack skeleton. Required features include a compliant slave state machine (Init, Safe-Operational, Operational), mailbox handlers, process data transport, and a basic distributed clock interface when requested. Optional/advanced features include tracing hooks, runtime parameter updates, SDO scaffolding, and unit-test skeletons. It also generates a skeleton ESI manifest and build/config templates to aid integration.\n\nInputs & Outputs: Inputs cover hardware profile, data sizes, PDO configuration, and timing expectations; outputs include portable C/C++ sources, headers, a Makefile or CMake configuration, and a sample ESI manifest. Validation enforces input ranges (clock > 0, memory nonnegative, PD size within constraints) and cross-field consistency (alignment, sizes, and feature selections). Outputs are structured for direct integration with existing toolchains and CI pipelines, with clear placeholders for device drivers and vendor-specific code.\n\nAlgorithms & Calculations: The generator performs simple budget calculations to verify timing feasibility based on clock frequency, intended cycle time, and processing overhead. It validates PDO layouts, memory budgets, and 1.5.3 feature sets, generating diagnostic notes when constraints cannot be satisfied. It also ensures compatibility with IEC 61158 and the standard ECAT slave information model.\n\nError & Edge Cases: If required inputs are missing or inconsistent (unknown MCU, zero clock, excessive PD size, or conflicting feature selections), generation fails with precise diagnostics and actionable recommendations. External data gaps (missing device headers or toolchain) trigger detailed remediation notes. Edge-case mappings (DC off, large PD) trigger alternative template branches.\n\nIndustry/Region & Localization: Adheres to IEC 61158 for EtherCAT slave information and 1.5.3 feature sets; uses SI units (Hz, bytes) and standard automation terminology with broad geographic applicability. The outputs are designed for translation-ready strings if localization is required.\n\nAssumptions & Exclusions: Assumes standard EtherCAT timing and supported MCU toolchains. Excludes generation of runtime binaries, vendor-specific optimizations, and non-standard extensions beyond 1.5.3. The tool does not execute hardware tests or provide platform-specific driver code beyond the skeleton templates.
