v1.10.2

v1.10.2 - Further reduce packet limits for USB reconnection robustness

v1.10.1

Added

• Extended watchdog breadcrumbs: Added NETWORK_REFRESH, USB_SEND, USB_RECONNECT, and USB_RECOVERY breadcrumbs for finer-grained watchdog timeout diagnostics

Fixed

• CRITICAL: Unbounded network processing: Limited EthernetManager::Refresh() to process maximum 10 packets per call, preventing watchdog timeouts when network accumulates many packets during USB reconnection
• Unbounded UDP processing: Limited processUdp() to process maximum 10 UDP packets per call, preventing main loop from blocking >128ms
• USB recovery watchdog feeding removed: Removed watchdog feeds during USB port recovery operations - if USB operations hang, watchdog should fire to recover system (feeding defeats the purpose of the watchdog)
• Watchdog timeout on USB reconnection: USB host reconnection and message sending now properly tracked with breadcrumbs, allowing identification of exactly where blocking occurs

v1.10.0

Added

• Error logging system: Circular buffer with 100 entries (8.8KB) supporting DEBUG/INFO/WARN/ERROR/CRITICAL levels
• Heartbeat log: 24-hour USB/network status tracker (2880 × 8-byte entries, 23KB) recorded every 30 seconds
• dump_error_log command: Retrieve diagnostic logs via USB or network
• USB auto-recovery: Detects stuck TX buffer (2s timeout) and automatically reopens port with watchdog protection

Changed

• Motor fault detection: 500ms grace period after clearing faults prevents false alarms during status register stabilization

Fixed

• Watchdog timeout during USB recovery: Removed blocking delay and added watchdog feeds during port operations
• Double-reset requirement: Single RESET command now properly clears watchdog recovery state
• USB connection persistence: Auto-recovery eliminates need for power cycle after app restart

v1.9.0

Changed

• Multi-step command handling: Commands with force_action=retract now send a single DONE message only when the entire sequence (move + retract) completes
  • Move completion sends INFO message: "Move complete, retracting..." or "Force limit reached, retracting..."
  • DONE message sent only when retract finishes, using original command name (e.g., DONE: move_abs)
  • Simplifies app-side logic - app waits for one DONE per command regardless of internal steps
  • Makes firmware responsible for its own multi-step command flow

v1.8.3

[1.8.3] - 2025-11-19

Fixed

• Watchdog timeouts: Fixed watchdog timer triggering during USB host detection and reconnection by queueing messages instead of blocking on ConnectorUsb.Send()
• USB reconnection: USB host reconnection message now only sends when sufficient buffer space is available (>40 bytes) to prevent blocking

v1.8.0

Fixed

• USB buffer improvements: Implemented automatic USB host connection detection to prevent buffer overflow
• Message filtering: Firmware now only sends USB/network messages when respective interfaces have active listeners

Changed

• Device naming portability: Replaced hardcoded "PRESSBOI" strings with DEVICE_NAME_UPPER and DEVICE_NAME_LOWER defines from config.h

v1.7.0

Changed

• Device definition restructuring: Moved device definition from Equipment Control App to firmware repository
  • Command definitions, telemetry schemas, and GUI layouts now live in pressboi/definition/ folder
  • Versioning of device protocol now happens alongside firmware
  • Equipment Control App automatically discovers and loads definitions from device paths
  • Supports both standalone definition folders and definitions embedded in firmware repos

Fixed

• USB telemetry: Fixed firmware not sending telemetry over USB serial when GUI not discovered via network
• USB message buffer: Implemented chunked message sending for telemetry packets larger than 64-byte USB CDC buffer
• Network discovery: Fixed firmware accepting discovery commands even when GUI already discovered, allowing reconnection
• Retract position telemetry: Fixed retract_pos reporting garbage values when motor not homed (now reports 0.0)
• Dual connection support: Both USB and network telemetry now stream simultaneously when both connections present

v1.6.1

Changed

• Repository structure: Reorganized project layout - moved libraries to lib/ folder and flattened pressboi/ subfolder to root
• Build system: Updated project paths to reflect new library locations

v1.6.0

Added

• Endpoint telemetry: New endpoint variable records the exact position (mm) where press moves stop

Fixed

• CRITICAL: Fixed infinite retract loop that caused watchdog timeouts when using retract or abort force actions.
• Fixed abort force action to only trigger retract when force limit is actually hit. Previously, abort action would retract even when the move completed normally without hitting the force limit.
• Fixed zero-step moves causing timeout errors. Moves with 0 steps now immediately return DONE instead of attempting to execute and timing out.

Changed

• Updated force_action parameter documentation to clarify behavior: retract always retracts on any completion, abort only retracts when force limit is hit.

v1.5.0

Added

• USB serial communication: Commands and telemetry now mirrored to USB serial (ConnectorUsb) alongside network communication
• Dual-channel command processing: USB commands processed identically to network commands through unified dispatcher

Changed

• Lowercase status text: Main state and motor status use lowercase for consistency (standby, busy, error, enabled, disabled, homed, not homed)
• USB processing limit: Characters per call capped at 32 to prevent watchdog timeout (128ms threshold)
