Biedt hardwarenabije drivers voor directe inkapseling en besturing van microcontroller-randapparatuur en interne registers.

Het modulecluster Microcontroller Abstraction (MCAL) omvat de drivers Port, Dio, Adc, Pwm, Spi en Wdg voor de hardwarenabije inkapseling en aansturing van de on-chip-randapparatuur (SWS_ECUStateManager p. 34). Tot de kerntaken behoren de pinconfiguratie voorafgaand aan toegang tot randapparatuur, het analoge en pulsgemoduleerde signaalbeheer evenals de tijdbewaakte programmabesturing ([SWS_Adc_00507], [SWS_Wdg_00155]). Centrale modus- en energietoestandswisselingen moeten daarbij strikt sequentieel en niet-re-entrant worden uitgevoerd ([SWS_Wdg_00107]).

Het modulecluster Microcontroller Abstraction (MCAL) kapselt de fysieke on-chip-bronnen van de microcontroller in en stelt gestandaardiseerde interfaces beschikbaar voor de I/O-hardware-abstractie (IoHwAb), de watchdog-interface (WdgIf) evenals EcuM en BswM (SWS_ECUStateManager p. 34). Het omvat de zes driverbouwstenen Port (pinmultiplexing), Dio (digitale in-/uitgang), Adc (analoog-digitaalomzetting), Pwm (pulsbreedtemodulatie), Spi (seriële randapparatuurcommunicatie) en Wdg (hardwarematige programmabesturingsbewaking) ([SWS_Adc_00507], [SWS_Pwm_00197], [SWS_Wdg_00155]).

De modules opereren in vaste afhankelijkheden: Port_Init configureert de pintoewijzing voordat drivers zoals Pwm of Adc de bijbehorende hardwareblokken activeren (AUTOSAR_CP_RS_PWMDriver p. 14, ModemanagementGuide p. 54). Databuffers worden via Adc_SetupResultBuffer aan applicatiezijde beschikbaar gesteld ([SWS_Adc_91000]), terwijl de watchdog-bediening asynchroon via timer-interrupts wordt ontkoppeld (AUTOSAR_SWS_WatchdogDriver p. 31).

Terwijl kanaal- en groepsgebonden driveraanroepen voor disjuncte instanties re-entrant zijn ([SWS_Pwm_91000], [SWS_Adc_00367]), vereisen modus- en toestandswisselingen strikt synchrone, niet-re-entrante paden ([SWS_Wdg_00107]). Om de energiebehoefte te verlagen voeren Adc en Pwm tweefasige power-state-overgangen uit met asynchrone gereedheidsmeldingen aan de IoHwAb ([SWS_Adc_00478], [SWS_Pwm_00183], AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57).

Bedieningsfouten zoals niet-geïnitialiseerde aanroepen worden gemeld aan de DET ([SWS_Pwm_00177]), terwijl hardwaredefecten worden gemeld aan de DEM ([SWS_Wdg_00111]). In het geval van degradatie maakt Wdg_SetTriggerCondition het mogelijk om via doorgifte van de time-out 0 gericht een ECU-reset te forceren ([SWS_Wdg_00155], SWS_WatchdogDriver p. 29).

Systeemarchitectuur & rol van het modulecluster

Het modulecluster van de microcontroller-abstractielaag (Microcontroller Abstraction Layer, MCAL) vormt het meest hardwarenabije fundament van het AUTOSAR Classic Platform. Het kapselt de registertoegangen van de on-chip-randapparatuureenheden in en biedt bovenliggende lagen een gestandaardiseerde, microcontrolleronafhankelijke interface. Binnen de lagenarchitectuur bedienen de drivers de I/O-hardware-abstractie (IoHwAb), de watchdog-interface (WdgIf) evenals centrale systeemservices zoals de ECU State Manager (EcuM) en de Basic Software Mode Manager (BswM) (SWS_ECUStateManager p. 34).

Het cluster omvat zes complementaire driverbouwstenen: Port verzorgt de globale pinconfiguratie en de multiplexing van de microcontroller-pins (AUTOSAR_CP_RS_PWMDriver p. 14). Dio realiseert de snelle, bit- en poortgewijze digitale-I/O-toegang, terwijl Spi synchrone en asynchrone seriële buscommunicatie naar on-board-randapparatuurbouwstenen inkapselt. Voor analoge en pulsgemoduleerde signalen stellen Adc ([SWS_Adc_00507]) en Pwm ([SWS_Pwm_00197]) geavanceerde omzettings- en modulatiediensten beschikbaar. Wdg bestuurt de hardwarematige tijdbewaking ter beveiliging van de integriteit van de programma-afloop ([SWS_Wdg_00155]).

Samenspel & interactiepaden tussen de modules

De modules opereren in duidelijk gedefinieerde signaal- en bufferstromen. De driver Port initialiseert vooraf de elektrische poortlogica en de multiplexing, waarna drivers zoals Pwm of Adc de toegewezen randapparatuurblokken aansturen, zonder kennis van de pad-schakeling te hoeven hebben (AUTOSAR_CP_RS_PWMDriver p. 14). Bij het uitlezen van interne logicatoestanden via [SWS_Pwm_00100] leest Pwm_GetOutputState de registertoestand van de PWM-eenheid uit en niet de fysieke poortpin ([SWS_Pwm_00108], AUTOSAR_SWS_PWMDriver p. 51).

In het analoge pad vraagt de bovenliggende IoHwAb metingen aan en stelt buffers aan applicatiezijde beschikbaar (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 55). Via [SWS_Adc_91000] initialiseert Adc_SetupResultBuffer de interne pointer naar het geheugenbereik van de aanroeper (AUTOSAR_SWS_ADCDriver p. 31). Na het triggeren van een omzetting via software ([SWS_Adc_00367]) of hardware-trigger ([SWS_Adc_91001]) worden ruwe gegevens in de buffer geschreven. De leestoegang vindt synchroon plaats via [SWS_Adc_00369] (kopiëren van de meest recente resultaten) of via [SWS_Adc_00375] door middel van Adc_GetStreamLastPointer (SWS_ADCDriver p. 27).

Het watchdog-pad scheidt de logische programmabesturing van de hardwarematige bediening (servicing): de WdgM bestuurt bewakingsbudgetten en stelt via het WdgIf met [SWS_Wdg_00155] het tijdvenster in Wdg_SetTriggerCondition in (SWS_WatchdogDriver p. 29). De feitelijke hardwarebediening vindt cyclisch plaats via hardware-timer-interrupts (AUTOSAR_SWS_WatchdogDriver p. 31). Externe watchdog-bouwstenen worden daarbij indien nodig via driverinstanties van Dio of Spi aangesproken ([SWS_Wdg_00111], AUTOSAR_SWS_WatchdogDriver p. 11).

Synchronisatie, re-entrantie en taakcontexten

De MCAL-drivers zijn onderworpen aan gedifferentieerde re-entrantievoorschriften. In module Pwm zijn besturingsfuncties zoals Pwm_SetDutyCycle ([SWS_Pwm_91000]), Pwm_SetPeriodAndDuty ([SWS_Pwm_91001]) en Pwm_SetOutputToIdle ([SWS_Pwm_91002]) re-entrant voor verschillende kanalen, maar mogen voor hetzelfde kanaal niet gelijktijdig worden aangeroepen (AUTOSAR_CP_SWS_PWMDriver p. 46). In module Adc zijn besturings- en lees-API's zoals Adc_StartGroupConversion ([SWS_Adc_00367]), Adc_StopGroupConversion ([SWS_Adc_00368]) en Adc_ReadGroup ([SWS_Adc_00369]) re-entrant met betrekking tot verschillende kanaalgroepen.

Daarentegen zijn centrale configuratie- en modus-API's strikt niet-re-entrant ontworpen. Dit geldt voor Wdg_SetMode ([SWS_Wdg_00107]), Wdg_SetTriggerCondition ([SWS_Wdg_00155]) evenals de initialisatie- en de-initialisatieroutines van alle drivers ([SWS_Adc_00366], [SWS_Pwm_00096]). Concurrerende aanroepen vanuit verschillende OS-taken moeten via SchM-exclusieve gebieden worden beschermd (AUTOSAR_SWS_WatchdogDriver p. 11).

Meldingen over events (bijv. flankwisselingen of het einde van een omzetting) worden via configureerbare callbacks zoals Pwm_Notification_<#Channel> ([SWS_Pwm_00105]) of Adc_Notification_Group_<x> ([SWS_Adc_91003]) vanuit de interruptcontext (ISR) geactiveerd. Bij activering van meldingen worden openstaande interruptflags gereset ([SWS_Pwm_91004]). Als meerdere ADC-groepen concurreren om omzetterbronnen, treedt afhankelijk van de configuratie een hardwarematige prioritering of softwarematige wachtrijvorming (queuing) ([SWS_Adc_00522]) met een configureerbaar abort/restart- of suspend/resume-mechanisme in werking ([SWS_Adc_00523], SWS_ADCDriver p. 97).

Typische levenscycli en bedrijfsmodi

De levenscyclus van de MCAL-drivers begint in de startfase van het totale systeem onder controle van de EcuM (SWS_ECUStateManager p. 34). Via BswM-regels wordt een deterministische volgorde afgedwongen: eerst initialiseert Port_Init de pinfunctionaliteiten (ModemanagementGuide p. 54). Pas daarna volgen randapparatuurdrivers zoals Dio_Init, Spi_Init, Adc_Init ([SWS_Adc_00365]), Pwm_Init ([SWS_Pwm_00095]) en Wdg_Init ([SWS_Wdg_00106], AUTOSAR_CP_SWS_PWMDriver p. 47).

In bedrijf kent Wdg drie statische modi: WDGIF_OFF_MODE, WDGIF_SLOW_MODE en WDGIF_FAST_MODE ([SWS_Wdg_00107]). De module Adc maakt onderscheid tussen one-shot- en continue omzettingen ([SWS_Adc_00515]) evenals single- en streaming-toegangsmodi ([SWS_Adc_00528], [SWS_Adc_00519]). De groepsstatus doorloopt daarbij de toestanden ADC_IDLE, ADC_BUSY, ADC_COMPLETED en ADC_STREAM_COMPLETED ([SWS_Adc_00513], [SWS_Adc_00374], SWS_ADCDriver p. 37).

Voor energiebesparingsmodi (Low Power) implementeren Adc en Pwm een gestandaardiseerd tweefasig power-state-protocol: eerst bereiden Adc_PreparePowerState ([SWS_Adc_00478]) en Pwm_PreparePowerState ([SWS_Pwm_00183]) de overgang voor ([SWS_Pwm_00165], [SWS_Adc_00527]). Na asynchrone voltooiing meldt de hardware-abstractie de gereedheid via callbacks zoals IoHwAb_Adc_NotifyReadyForPowerState<#Mode> ([SWS_Adc_00480]). Ten slotte schakelen Adc_SetPowerState ([SWS_Adc_00475]) en Pwm_SetPowerState ([SWS_Pwm_00166]) de hardware naar de doeltoestand (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57). De cyclische bewaking wordt in taken gewaarborgd door Pwm_Main_PowerTransitionManager ([SWS_Pwm_00189], [SWS_Pwm_00190]).

Bij een systeemshutdown of reset brengen de-initialisatiediensten zoals Adc_DeInit ([SWS_Adc_00366], AUTOSAR_SWS_ADC_Driver p. 76) en Pwm_DeInit ([SWS_Pwm_00096], AUTOSAR_SWS_PWMDriver p. 47) de eenheden naar een veilige rusttoestand en deactiveren alle interrupts.

Foutafhandeling, DET-tracing en degradatie

Fouten worden strikt gescheiden in ontwikkelings- en productiefouten. Bij actieve ontwikkelingscontrole melden de drivers aanroepen vóór voltooide initialisatie aan de Default Error Tracer (DET), bijvoorbeeld via PWM_E_UNINIT ([SWS_Pwm_00177], [SWS_Pwm_00104]) of ADC_E_UNINIT ([SWS_Adc_00476]). Pointerparameters worden gecontroleerd op NULL, bijvoorbeeld bij GetVersionInfo via ADC_E_PARAM_POINTER ([SWS_Adc_00376]) en WDG_E_PARAM_POINTER ([SWS_Wdg_00109]).

Runtimefouten beveiligen ontoelaatbare bedrijfsovergangen: als Pwm_SetPowerState wordt aangeroepen terwijl kanalen zich niet in de IDLE-toestand bevinden of er nog actieve meldingen zijn, meldt de driver de runtimefout PWM_E_NOT_DISENGAGED ([SWS_Pwm_00202]). Bij Adc leidt de poging om een bezette kanaalgroep in configuraties zonder queuing opnieuw te triggeren tot de runtimemelding ADC_E_BUSY aan de DET (SWS_ADCDriver p. 95).

Ernstige productiefouten en uitval van randapparatuur worden gemeld aan de Diagnostic Event Manager (DEM) via Dem_SetEventStatus ([SWS_Wdg_00111]). Voor degradatie in noodbedrijfsmodi biedt Pwm_SetOutputToIdle de onmiddellijke deactivering van individuele PWM-uitgangen ([SWS_Pwm_91002]). In de watchdog-driver maakt het instellen van de trigger-time-out op de waarde 0 het onmiddellijk stoppen van de servicing mogelijk en dwingt het een snelle ECU-reset af ([SWS_Wdg_00155], [SWS_Wdg_00136], SWS_WatchdogDriver p. 29).
