Set di comandi SCPI per smartIO 8x24
Utilizzo generale
The help could be called in several ways:
'__?' => Print all commands
'__? ?' => Print the list of all sections
'can:__?' => Print the 'can' section help
'__? can' => Other way to print the 'can' section help
'__? sta' => Print commands starting with 'sta'
The commands can be entered in the short form (shown in capital letters in the help)
or in the long form. Intermediate lengths are not permitted.
The commands can be specified in uppercase or lowercase letters.
Parameters are separated with commas.
Several commands in one line are separated with ';'.
Comments start with '//'.

Status LED1
Il LED singolo a pixel WS2812 mostra la sequenza di boot, lo stato idle e le classi di errore come sequenze di colori.
Il tempo di bit di base è impostabile tramite system:bitlen (default 250 ms); tutti gli altri tempi
(separatori, pause) sono multipli fissi di questo valore. L'autotest subito dopo l'accensione è l'unica
eccezione e viene eseguito sempre con tempo fisso, indipendentemente da system:bitlen.
Sequenza dopo l'accensione:
- Autotest: rosso – verde – blu, 200 ms ciascuno, senza pausa tra l'uno e l'altro.
- Pausa (3× il tempo di bit di base).
- Annuncio della versione del firmware (ripetibile tramite
system:swver?): blu (preambolo, 3×) → versione principale (6 bit, MSB first, bianco = 1 / verde = 0, 1× il tempo di bit di base per ogni bit incl. fase finale) → giallo (separatore, 3×) → versione decimale (6 bit, stesso schema) → pausa (4×, sync). - Successivamente heartbeat in idle.
Heartbeat in idle: 1 volta al secondo verde per un breve istante, altrimenti spento. Finché system:admin è attivo, al posto del verde viene utilizzato il giallo (promemoria visibile che la modalità admin è attiva).
Segnalazione degli errori (sostituisce l'heartbeat in idle finché è attiva almeno una classe di errore): rosso (preambolo, 3×) → per ogni classe di errore attiva un codice a 4 bit (bianco = 1 / rosso = 0, MSB first); per le classi relative ai canali segue una pausa (3×) e successivamente una bitmap dei canali a 8 bit (rosso = 1 / canale interessato, verde = 0 / canale ok), canale 0 per primo, canale 7 per ultimo. Tra più codici attivi si trova un separatore giallo (3×); segue una pausa di sync (4×), poi si torna al preambolo (se gli errori sono ancora attivi) oppure all'heartbeat in idle.
| Codice | Significato | Tipo |
|---|---|---|
| 1 | Errore CAN | globale |
| 2 | ADC bloccato (interrupt DR da ~3s senza nuovi dati) | globale |
| 3 | Reset watchdog rilevato (una sola volta, solo subito dopo il boot) | globale |
| 4 | Errore CRC del registro di configurazione MCP3914 (adc:crc?) | globale |
| 5 | Reset da panic rilevato (stack overflow, corruzione dell'heap, eccezione, ...), una sola volta, solo subito dopo il boot1 | globale |
| 8 | Overrange | per canale |
| 9 | Errore CMT (Common-Mode-Trim mancante/fuori campo, calib:cmstat?) | per canale |
| 10 | Calibrazione mancante nel gain/nella modalità attivi | per canale |
I codici 1-5 e 8/9/10 corrispondono 1:1 ai bit nell'item CAN 8120 (codici 1-5) ovvero alle bitmap dei canali negli item CAN 8100 (Overrange), 8101 (errore CMT) e 8102 (errore No-CAL) -- vedere CAN Mapping.
I reset da watchdog e da panic (codici 3/5) scrivono inoltre immediatamente al boot una voce nel
registro eventi (file:log)1 -- in quanto uniche classi di errore rare ma critiche che sono rilevabili solo dopo
il riavvio. Errori CAN, overrange ed errori CMT/CAL restano intenzionalmente solo telemetria
LED/CAN, senza voce nel registro eventi.
Diagrammi temporali per le sequenze più importanti (sequenza di power-up, versione firmware 1.37, funzionamento normale e admin in idle, un singolo codice di errore, più codici di errore globali simultanei, nonché un codice relativo ai canali su canali selezionati):
