CanMV K230 SDK Release Notes v1.8

We are pleased to announce the release of CanMV K230 v1.8. This release focuses on IDE debugging enhancements, new MicroPython modules (OTP, time/NTP), UART and USB improvements, VICAP stream handling refinements, and expanded library support including libwebsockets and mbedTLS.

🚀 Key Highlights

  • IDE Debugging Experience: Added IDE capability protocol, virtual touch support, stdout capture, raw input handling, auto-exec control, and streamlined script-running checks for a smoother development workflow.
  • New MicroPython Modules: Introduced machine.OTP module with read and lock functionality, and time module with clock class and NTP synchronization support.
  • UART Transmission Robustness: Enhanced UART write path with full-write support for better synchronization, and improved handling of undelivered data across write calls.
  • USB Stack Improvements: Reworked DWC2 device FIFO allocation to be dynamic and config-driven, implemented IN endpoint quiescing and TX FIFO flushing on stall, and enhanced USB error logging with Debug Descriptor support.
  • New Libraries: Added libwebsockets integration with necessary stubs, and mbedTLS support in RT-Smart libraries.
  • Faster Boot: Further optimized boot time in MPP.

📦 Component Updates

1. CanMV Core

  • IDE Debugging & Protocol: Added IDE capability protocol and virtual touch support, enhanced IDE debugging output with stdout capture and raw input handling, added auto-exec control and ide_dbg_is_connected function, and streamlined script-running checks for better reliability.
  • MicroPython APIs: Added machine.OTP module with read and lock functionality for one-time programmable memory access, and time module with clock class and NTP synchronization function.
  • UART & I/O: Enhanced UART transmission with full-write path for better synchronization, and improved handling to retain undelivered data across write calls.
  • Sensor & VICAP: Refactored VICAP management functions for improved stream handling, updated sensor2 pixel format to YUV420SP with adjusted display binding, added database parse mode handling to Sensor class, and fixed CSC binding channel ID.
  • Build & Tooling: Added packaging scripts for CanMV VS Code examples and stubs with CDN layout, and removed obsolete configuration entries from build and release workflows.
