Add a structured firmware release (“Rr52c.03a”) focused on device stability, secure updateability, telemetry for diagnostics, modular driver architecture, and developer-friendly tooling to reduce field failures and speed future feature delivery.
From a modern security perspective, Rr52c.03a is considered vulnerable and legacy. Rr52c.03a Firmware
An elusive bug caused the real-time interrupt to occasionally exceed 15 µs during USB + CAN concurrency. .03a reorders interrupt priorities and offloads non-critical housekeeping to the idle task.
Result: Maximum interrupt latency now stays under 9 µs — critical for stepper pulse generation and encoder timestamping. Add a structured firmware release (“Rr52c
