Fournit des pilotes bas niveau pour l'encapsulation directe et le pilotage des périphériques de microcontrôleur et des registres internes.
Fournit des pilotes bas niveau pour l'encapsulation directe et le pilotage des périphériques de microcontrôleur et des registres internes.
Le cluster de modules Microcontroller Abstraction (MCAL) comprend les pilotes Port, Dio, Adc, Pwm, Spi et Wdg pour l'encapsulation bas niveau et le pilotage des périphériques intégrés à la puce (SWS_ECUStateManager p. 34). Parmi les tâches fondamentales figurent la configuration des broches avant les accès aux périphériques, la gestion des signaux analogiques et modulés par impulsions ainsi que le contrôle d'exécution surveillé dans le temps ([SWS_Adc_00507], [SWS_Wdg_00155]). Les changements centraux de mode et d'état d'énergie doivent y être exécutés de manière strictement séquentielle et non réentrante ([SWS_Wdg_00107]).
Le cluster de modules Microcontroller Abstraction (MCAL) encapsule les ressources physiques sur puce du microcontrôleur et met à disposition des interfaces standardisées pour l'abstraction matérielle des E/S (IoHwAb), l'interface de watchdog (WdgIf) ainsi que EcuM et BswM (SWS_ECUStateManager p. 34). Il comprend les six composants de pilote Port (multiplexage de broches), Dio (entrées/sorties numériques), Adc (conversion analogique-numérique), Pwm (modulation de largeur d'impulsion), Spi (communication série avec les périphériques) et Wdg (surveillance matérielle du déroulement du programme) ([SWS_Adc_00507], [SWS_Pwm_00197], [SWS_Wdg_00155]).
Les modules fonctionnent selon des dépendances fixes : Port_Init configure l'affectation des broches avant que des pilotes tels que Pwm ou Adc n'activent les blocs matériels associés (AUTOSAR_CP_RS_PWMDriver p. 14, ModemanagementGuide p. 54). Les tampons de données sont fournis côté application via Adc_SetupResultBuffer ([SWS_Adc_91000]), tandis que la desserte du watchdog est découplée de manière asynchrone via des interruptions de temporisateur (AUTOSAR_SWS_WatchdogDriver p. 31).
Diagramme d'architecture : architecture en couches et classification du cluster MCAL. Sources : SWS_ECUStateManager p. 34, AUTOSAR_CP_RS_PWMDriver p. 14.
Tandis que les appels de pilote liés aux canaux et aux groupes sont réentrants pour des instances disjointes ([SWS_Pwm_91000], [SWS_Adc_00367]), les commutations de mode et d'état requièrent des chemins strictement synchrones et non réentrants ([SWS_Wdg_00107]). Afin de réduire la consommation d'énergie, Adc et Pwm exécutent des transitions d'état de puissance diphasiques avec des notifications de disponibilité asynchrones envoyées à IoHwAb ([SWS_Adc_00478], [SWS_Pwm_00183], AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57).
Les mauvaises manipulations telles que les appels non initialisés sont signalées au DET ([SWS_Pwm_00177]), tandis que les défaillances matérielles sont signalées au DEM ([SWS_Wdg_00111]). En cas de dégradation, Wdg_SetTriggerCondition permet de provoquer de manière ciblée une réinitialisation de l'ECU en transmettant le timeout 0 ([SWS_Wdg_00155], SWS_WatchdogDriver p. 29).
Architecture système & rôle du cluster de modules
Le cluster de modules de la couche d'abstraction de microcontrôleur (Microcontroller Abstraction Layer, MCAL) constitue le socle le plus proche du matériel de l'AUTOSAR Classic Platform. Il encapsule les accès aux registres des unités périphériques sur puce et fournit aux couches supérieures une interface standardisée et indépendante du microcontrôleur. Au sein de l'architecture en couches, les pilotes desservent l'abstraction matérielle des E/S (IoHwAb), l'interface de watchdog (WdgIf) ainsi que des services système centraux tels que l'ECU State Manager (EcuM) et le Basic Software Mode Manager (BswM) (SWS_ECUStateManager p. 34).
Le cluster comprend six composants de pilote complémentaires : Port prend en charge la configuration globale des broches et le multiplexage des broches du microcontrôleur (AUTOSAR_CP_RS_PWMDriver p. 14). Dio réalise l'accès numérique rapide aux E/S par bit et par port, tandis que Spi encapsule les communications série synchrones et asynchrones vers les composants périphériques intégrés sur la carte. Pour les signaux analogiques et modulés par impulsions, Adc ([SWS_Adc_00507]) et Pwm ([SWS_Pwm_00197]) fournissent des services élaborés de conversion et de modulation. Wdg contrôle la surveillance temporelle matérielle afin de sécuriser l'intégrité de l'exécution du programme ([SWS_Wdg_00155]).

Interaction & voies d'interaction entre les modules
Les modules opèrent selon des flux de signaux et de tampons clairement définis. Le pilote Port initialise au préalable la logique de port électrique et le multiplexage, après quoi des pilotes tels que Pwm ou Adc pilotent les blocs périphériques attribués sans avoir besoin de connaître le câblage des plots (AUTOSAR_CP_RS_PWMDriver p. 14). Lors de la lecture d'états logiques internes via [SWS_Pwm_00100], Pwm_GetOutputState lit l'état du registre de l'unité PWM et non la broche de port physique ([SWS_Pwm_00108], AUTOSAR_SWS_PWMDriver p. 51).
Dans le chemin analogique, l'entité supérieure IoHwAb demande des mesures et met à disposition des tampons côté application (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 55). Au moyen de [SWS_Adc_91000], Adc_SetupResultBuffer initialise le pointeur interne vers la zone mémoire de l'appelant (AUTOSAR_SWS_ADCDriver p. 31). Après le déclenchement d'une conversion par voie logicielle ([SWS_Adc_00367]) ou par déclencheur matériel ([SWS_Adc_91001]), les données brutes sont écrites dans le tampon. L'accès en lecture s'effectue de manière synchrone via [SWS_Adc_00369] (copie des résultats les plus récents) ou via [SWS_Adc_00375] au moyen de Adc_GetStreamLastPointer (SWS_ADCDriver p. 27).
Le chemin du watchdog sépare le contrôle logique du déroulement de la desserte matérielle : WdgM gère les budgets de surveillance et définit la fenêtre temporelle dans Wdg_SetTriggerCondition via WdgIf avec [SWS_Wdg_00155] (SWS_WatchdogDriver p. 29). La desserte matérielle proprement dite s'effectue de manière cyclique via des interruptions de temporisateur matériel (AUTOSAR_SWS_WatchdogDriver p. 31). Les composants de watchdog externes sont alors sollicités si nécessaire via des instances de pilote de Dio ou Spi ([SWS_Wdg_00111], AUTOSAR_SWS_WatchdogDriver p. 11).
Diagramme de séquence : interaction de WdgM, WdgIf et Wdg lors de la prolongation cyclique de déclenchement et de la commutation de mode. Sources : AUTOSAR_SWS_WatchdogDriver p. 31, AUTOSAR_SWS_WatchdogDriver p. 34, [SWS_Wdg_00155], [SWS_Wdg_00107].
Synchronisation, réentrance et contextes de tâches
Les pilotes MCAL sont soumis à des règles de réentrance différenciées. Dans le module Pwm, les fonctions de commande telles que Pwm_SetDutyCycle ([SWS_Pwm_91000]), Pwm_SetPeriodAndDuty ([SWS_Pwm_91001]) et Pwm_SetOutputToIdle ([SWS_Pwm_91002]) sont réentrantes pour différents canaux, mais ne doivent pas être appelées de manière concurrente pour le même canal (AUTOSAR_CP_SWS_PWMDriver p. 46). Dans le module Adc, les API de commande et de lecture telles que Adc_StartGroupConversion ([SWS_Adc_00367]), Adc_StopGroupConversion ([SWS_Adc_00368]) et Adc_ReadGroup ([SWS_Adc_00369]) sont réentrantes pour différents groupes de canaux.
En revanche, les API centrales de configuration et de mode sont strictement non réentrantes. Cela s'applique à Wdg_SetMode ([SWS_Wdg_00107]), Wdg_SetTriggerCondition ([SWS_Wdg_00155]) ainsi qu'aux routines d'initialisation et de désinitialisation de l'ensemble des pilotes ([SWS_Adc_00366], [SWS_Pwm_00096]). Les appels concurrents provenant de différentes tâches de l'OS doivent être protégés par des zones exclusives SchM (AUTOSAR_SWS_WatchdogDriver p. 11).
Les notifications d'événements (par ex. changement de front ou fin de conversion) sont déclenchées depuis le contexte d'interruption (ISR) via des rappels configurables tels que Pwm_Notification_<#Channel> ([SWS_Pwm_00105]) ou Adc_Notification_Group_<x> ([SWS_Adc_91003]). Lors de l'activation des notifications, les indicateurs d'interruption en attente sont réinitialisés ([SWS_Pwm_91004]). Si plusieurs groupes ADC se disputent les ressources de conversion, une priorisation matérielle ou une mise en file d'attente logicielle ([SWS_Adc_00522]) intervient selon la configuration, avec un mécanisme configurable d'abandon/redémarrage (Abort/Restart) ou de suspension/reprise (Suspend/Resume) ([SWS_Adc_00523], SWS_ADCDriver p. 97).
Cycles de vie et modes de fonctionnement typiques
Le cycle de vie des pilotes MCAL commence lors de la phase de démarrage de l'ensemble du système sous le contrôle de EcuM (SWS_ECUStateManager p. 34). Un ordre déterministe est imposé via des règles BswM : Port_Init initialise d'abord les fonctionnalités des broches (ModemanagementGuide p. 54). Ce n'est qu'ensuite que suivent les pilotes périphériques tels que Dio_Init, Spi_Init, Adc_Init ([SWS_Adc_00365]), Pwm_Init ([SWS_Pwm_00095]) et Wdg_Init ([SWS_Wdg_00106], AUTOSAR_CP_SWS_PWMDriver p. 47).
En fonctionnement, Wdg connaît trois modes statiques : WDGIF_OFF_MODE, WDGIF_SLOW_MODE et WDGIF_FAST_MODE ([SWS_Wdg_00107]). Le module Adc distingue les conversions One-Shot et Continuous ([SWS_Adc_00515]) ainsi que les modes d'accès Single et Streaming ([SWS_Adc_00528], [SWS_Adc_00519]). L'état du groupe traverse alors les états ADC_IDLE, ADC_BUSY, ADC_COMPLETED et ADC_STREAM_COMPLETED ([SWS_Adc_00513], [SWS_Adc_00374], SWS_ADCDriver p. 37).
Pour les modes d'économie d'énergie (Low Power), Adc et Pwm implémentent un protocole standardisé de Power-State en deux phases : d'abord, Adc_PreparePowerState ([SWS_Adc_00478]) et Pwm_PreparePowerState ([SWS_Pwm_00183]) préparent la transition ([SWS_Pwm_00165], [SWS_Adc_00527]). Après achèvement asynchrone, l'abstraction matérielle signale la disponibilité via des callbacks tels que IoHwAb_Adc_NotifyReadyForPowerState<#Mode> ([SWS_Adc_00480]). Enfin, Adc_SetPowerState ([SWS_Adc_00475]) et Pwm_SetPowerState ([SWS_Pwm_00166]) font basculer le matériel dans l'état cible (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57). La surveillance cyclique est assurée dans des tâches par Pwm_Main_PowerTransitionManager ([SWS_Pwm_00189], [SWS_Pwm_00190]).
Lors de l'arrêt du système (System-Shutdown) ou d'un reset, des services de désinitialisation tels que Adc_DeInit ([SWS_Adc_00366], AUTOSAR_SWS_ADC_Driver p. 76) et Pwm_DeInit ([SWS_Pwm_00096], AUTOSAR_SWS_PWMDriver p. 47) font passer les unités dans un état de repos sécurisé et désactivent toutes les interruptions.
Diagramme de séquence : changement d'état de puissance (Power-State) asynchrone en deux phases dans le cluster MCAL via BswM et IoHwAb. Sources : AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57, [SWS_Adc_00478], [SWS_Pwm_00183], [SWS_Adc_00475], [SWS_Pwm_00166].
Gestion des erreurs, traçage DET et dégradation
Les erreurs sont strictement séparées entre erreurs de développement et erreurs de production. Lorsque le contrôle de développement est actif, les pilotes signalent les appels antérieurs à l'initialisation au Default Error Tracer (DET), par exemple via PWM_E_UNINIT ([SWS_Pwm_00177], [SWS_Pwm_00104]) ou ADC_E_UNINIT ([SWS_Adc_00476]). Les paramètres de pointeur sont vérifiés par rapport à NULL, par exemple pour GetVersionInfo via ADC_E_PARAM_POINTER ([SWS_Adc_00376]) et WDG_E_PARAM_POINTER ([SWS_Wdg_00109]).
Les erreurs d'exécution sécurisent les transitions opérationnelles non autorisées : si Pwm_SetPowerState est appelé alors que des canaux ne sont pas à l'état IDLE ou que des notifications sont encore actives, le pilote signale l'erreur d'exécution PWM_E_NOT_DISENGAGED ([SWS_Pwm_00202]). Dans le cas de Adc, la tentative de redéclencher un groupe de canaux occupé dans des configurations sans mise en file d'attente (Queuing) entraîne le signalement d'exécution ADC_E_BUSY au DET (SWS_ADCDriver p. 95).
Les erreurs de production graves et les défaillances de périphériques sont signalées au Diagnostic Event Manager (DEM) via Dem_SetEventStatus ([SWS_Wdg_00111]). Pour la dégradation vers des modes de fonctionnement dégradé, Pwm_SetOutputToIdle fournit la désactivation immédiate des sorties PWM individuelles ([SWS_Pwm_91002]). Dans le pilote Watchdog, définir le timeout de déclenchement à la valeur 0 permet l'arrêt immédiat du servicing et force un reset ECU rapide ([SWS_Wdg_00155], [SWS_Wdg_00136], SWS_WatchdogDriver p. 29).
