F4.5: consola UART interactiva de operador#83
Merged
Conversation
…oot) Añade una consola de operador por UART real sobre la capa rugus-kernel, desacoplada del hardware por el trait `ConsoleOut` (mismo patrón que `StatusLeds`/`FaultObserver`). El kernel acumula la línea byte a byte, hace eco y parsea comandos que inspeccionan (`ps`/`mem`/`faults`) y actúan (`respawn`/`reboot`) sobre el estado vivo, sin `alloc` ni `defmt` y sin bloquear al supervisor. - rugus-kernel/console.rs: `Console` (parser de línea + comandos + NumBuf), trait `ConsoleOut` y anillo SPSC `RxRing` sin bloqueo (ISR productor / supervisor consumidor) reutilizable entre placas. - rugus-kernel/lib.rs: wrappers de introspección (task_state_name, is_user_task, task_priority, stack_*, heap_* cfg-gated por `alloc`) y `reboot()`. - rugus-core: `sched::task_state_name`/`is_user_task` y `heap::used/free/size`. - HAL F4/F7: `enable_rx_irq()` (RXNEIE) + `isr_read_byte()` para drenar RX desde el `#[interrupt] fn USART2`. - Ejemplos F407/F769: handler USART2 → RxRing, ConsoleOut sobre Usart2, drenado en el supervisor, NVIC unmask + greet. Validado por RTT en ambas placas (loopback PASS, "UART console ready", selftests PASS, supervisor vivo). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
