Developed and enhanced ISO-TP (ISO 15765-2) support for ESP-IDF within the espressif/idf-extra-components repository, enabling robust CAN/TWAI communication for automotive applications. Designed a modular isotp-c library and esp_isotp component in C, introducing non-blocking APIs, multi-instance support, and segmentation for large payloads. Extended the transport layer to handle both 11-bit and 29-bit CAN IDs with thread safety and ISR-safe asynchronous transmission using pre-allocated buffers. Integrated callback-based, event-driven interfaces and centralized configuration via Kconfig and YAML, simplifying deployment and improving throughput, latency, and interoperability for embedded systems requiring reliable protocol implementation and flexible communication workflows.

Sep 1, 2025Monthly summary for 2025-09: Implemented ISO-TP enhancements in espressif/idf-extra-components to improve CAN transport reliability, performance, and usability. Key deliverables include 29-bit ID support with thread safety, non-blocking per-message ID transmission with ISR-safe operation using pre-allocated TX buffers, and a callback-based event-driven interface with automatic ID detection. Fixed a critical issue in asynchronous TWAI sending by pre-allocating TX buffers to enable interrupt-context sends. Result: improved throughput, lower latency, simpler integration, and reduced configuration complexity for developers.

Aug 1, 2025Month: 2025-08 Key features delivered: - ISO-TP support for ESP-IDF (ISO 15765-2) over CAN/TWAI implemented via a new isotp-c library and the esp_isotp component. This enables end-to-end ISO-TP transmission with segmentation/reassembly, and introduces a non-blocking API with multi-instance support. Major bugs fixed: - No major bugs fixed this month. (no regressions reported related to the new ISO-TP stack) Overall impact and accomplishments: - Expanded ESP-IDF’s automotive communications capabilities with ISO-TP, enabling reliable transmission of large payloads and improved interoperability with CAN networks. - Reduced integration effort for automotive-focused projects and opened new use cases (diagnostics, firmware updates) thanks to a modular, scalable implementation. - Strengthened product readiness for automotive customers by providing a centralized configuration path and a reusable isotp-c library. Technologies/skills demonstrated: - ISO-TP protocol implementation and automotive-grade library design (isotp-c) - ESP-IDF component development (esp_isotp) and modular architecture - Non-blocking, multi-instance API design and segmentation/reassembly patterns - SDK config integration for centralized, scalable deployment Commit highlights: - 465046b74311e0fe6ae38a98214d140563edec8d — feat: Add isotp-c library - 233b082eacca9079fcdd7dc5de6208666d6e8128 — refactor(isotp): update configuration to use SDK config values - fce267a0fc19104e70b954e53863e8573de61f53 — feat(isotp): add the esp_isotp component
