Disponibiliza drivers de baixo nível para encapsulamento e controle diretos de periféricos do microcontrolador e registradores internos.

O cluster de módulos Microcontroller Abstraction (MCAL) compreende os drivers Port, Dio, Adc, Pwm, Spi e Wdg para o encapsulamento de baixo nível e acionamento dos periféricos on-chip (SWS_ECUStateManager p. 34). Entre as tarefas centrais estão a configuração de pinos antes dos acessos a periféricos, o gerenciamento de sinais analógicos e modulados por pulso, bem como o controle de execução monitorado por tempo ([SWS_Adc_00507], [SWS_Wdg_00155]). Mudanças centrais de modo e de estado de energia devem ser executadas estritamente de forma sequencial e não reentrante ([SWS_Wdg_00107]).

O cluster de módulos Microcontroller Abstraction (MCAL) encapsula os recursos físicos on-chip do microcontrolador e disponibiliza interfaces padronizadas para a abstração de hardware de E/S (IoHwAb), o Watchdog-Interface (WdgIf), bem como EcuM e BswM (SWS_ECUStateManager p. 34). Ele compreende os seis blocos de drivers Port (multiplexação de pinos), Dio (entrada/saída digital), Adc (conversão analógico-digital), Pwm (modulação por largura de pulso), Spi (comunicação serial de periféricos) e Wdg (monitoramento de execução por hardware) ([SWS_Adc_00507], [SWS_Pwm_00197], [SWS_Wdg_00155]).

Os módulos operam em dependências fixas: Port_Init configura a pinagem antes que drivers como Pwm ou Adc ativem os blocos de hardware correspondentes (AUTOSAR_CP_RS_PWMDriver p. 14, ModemanagementGuide p. 54). Buffers de dados são disponibilizados pelo lado da aplicação via Adc_SetupResultBuffer ([SWS_Adc_91000]), enquanto o acionamento do watchdog é desacoplado de forma assíncrona através de interrupções de temporizador (AUTOSAR_SWS_WatchdogDriver p. 31).

Diagrama de arquitetura: Arquitetura em camadas e classificação do cluster MCAL. Fontes: SWS_ECUStateManager p. 34, AUTOSAR_CP_RS_PWMDriver p. 14.

Enquanto chamadas de driver relacionadas a canais e grupos são reentrantes para instâncias disjuntas ([SWS_Pwm_91000], [SWS_Adc_00367]), comutações de modo e de estado exigem caminhos estritamente síncronos e não reentrantes ([SWS_Wdg_00107]). Para redução do consumo de energia, Adc e Pwm executam transições de Power-State bifásicas com notificações assíncronas de prontidão para o IoHwAb ([SWS_Adc_00478], [SWS_Pwm_00183], AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57).

Operações incorretas, como chamadas não inicializadas, são reportadas ao DET ([SWS_Pwm_00177]), enquanto defeitos de hardware são reportados ao DEM ([SWS_Wdg_00111]). Em caso de degradação, Wdg_SetTriggerCondition permite provocar deliberadamente um reset da ECU passando o timeout 0 ([SWS_Wdg_00155], SWS_WatchdogDriver p. 29).

Arquitetura do sistema & papel do cluster de módulos

O cluster de módulos da camada de abstração de microcontrolador (Microcontroller Abstraction Layer, MCAL) forma a base mais próxima do hardware da AUTOSAR Classic Platform. Ele encapsula os acessos aos registradores dos periféricos on-chip e disponibiliza para as camadas superiores uma interface padronizada e independente de microcontrolador. Dentro da arquitetura em camadas, os drivers atendem a abstração de hardware de E/S (IoHwAb), o Watchdog-Interface (WdgIf), bem como serviços centrais do sistema como o ECU State Manager (EcuM) e o Basic Software Mode Manager (BswM) (SWS_ECUStateManager p. 34).

O cluster compreende seis blocos de drivers complementares: Port assume a configuração global de pinos e a multiplexação dos pinos do microcontrolador (AUTOSAR_CP_RS_PWMDriver p. 14). Dio realiza o acesso digital de E/S rápido, por bit e por porta, enquanto Spi encapsula comunicações seriais síncronas e assíncronas de barramento para componentes periféricos on-board. Para sinais analógicos e modulados por pulso, Adc ([SWS_Adc_00507]) e Pwm ([SWS_Pwm_00197]) disponibilizam serviços avançados de conversão e modulação. Wdg controla a temporização baseada em hardware para salvaguarda da integridade da execução do programa ([SWS_Wdg_00155]).

Diagrama de arquitetura: Arquitetura em camadas e classificação estrutural do cluster MCAL entre serviços de sistema, camadas de abstração e periféricos. Fontes: SWS_ECUStateManager p. 34, AUTOSAR_CP_RS_PWMDriver p. 14, AUTOSAR_SWS_WatchdogDriver p. 11.

Interação e caminhos de interação entre os módulos

Os módulos operam em fluxos de sinais e de buffers claramente definidos. O driver Port inicializa previamente a lógica elétrica de portas e a multiplexação, após o que drivers como Pwm ou Adc acionam os blocos de periféricos associados sem necessitar de conhecimento sobre a ligação dos pads (AUTOSAR_CP_RS_PWMDriver p. 14). Na leitura de estados lógicos internos via [SWS_Pwm_00100], Pwm_GetOutputState lê o estado de registrador da unidade PWM e não o pino físico da porta ([SWS_Pwm_00108], AUTOSAR_SWS_PWMDriver p. 51).

No caminho analógico, o IoHwAb de nível superior solicita medições e disponibiliza buffers do lado da aplicação (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 55). Por meio de [SWS_Adc_91000], Adc_SetupResultBuffer inicializa o ponteiro interno para a área de memória do chamador (AUTOSAR_SWS_ADCDriver p. 31). Após o disparo de uma conversão por software ([SWS_Adc_00367]) ou por trigger de hardware ([SWS_Adc_91001]), dados brutos são gravados no buffer. O acesso de leitura ocorre de forma síncrona via [SWS_Adc_00369] (cópia dos resultados mais recentes) ou via [SWS_Adc_00375] através de Adc_GetStreamLastPointer (SWS_ADCDriver p. 27).

O caminho de watchdog separa o controle lógico da execução do servicing de hardware: o WdgM controla orçamentos de monitoramento e define a janela de tempo em Wdg_SetTriggerCondition por meio do WdgIf com [SWS_Wdg_00155] (SWS_WatchdogDriver p. 29). O atendimento real ao hardware ocorre ciclicamente através de interrupções de temporizador de hardware (AUTOSAR_SWS_WatchdogDriver p. 31). Componentes externos de watchdog são acessados, quando necessário, através de instâncias de driver de Dio ou Spi ([SWS_Wdg_00111], AUTOSAR_SWS_WatchdogDriver p. 11).

Diagrama de sequência: Interação de WdgM, WdgIf e Wdg na extensão cíclica de trigger e comutação de modo. Fontes: AUTOSAR_SWS_WatchdogDriver p. 31, AUTOSAR_SWS_WatchdogDriver p. 34, [SWS_Wdg_00155], [SWS_Wdg_00107].

Sincronização, reentrância e contextos de tarefas

Os drivers MCAL estão sujeitos a regras de reentrância diferenciadas. No módulo Pwm, funções de controle como Pwm_SetDutyCycle ([SWS_Pwm_91000]), Pwm_SetPeriodAndDuty ([SWS_Pwm_91001]) e Pwm_SetOutputToIdle ([SWS_Pwm_91002]) são reentrantes para canais diferentes, mas não devem ser chamadas concorrentemente para o mesmo canal (AUTOSAR_CP_SWS_PWMDriver p. 46). No módulo Adc, APIs de controle e leitura como Adc_StartGroupConversion ([SWS_Adc_00367]), Adc_StopGroupConversion ([SWS_Adc_00368]) e Adc_ReadGroup ([SWS_Adc_00369]) são reentrantes em relação a grupos de canais diferentes.

Por outro lado, APIs centrais de configuração e de modo são estritamente projetadas como não reentrantes. Isso se aplica a Wdg_SetMode ([SWS_Wdg_00107]), Wdg_SetTriggerCondition ([SWS_Wdg_00155]), bem como às rotinas de inicialização e desinicialização de todos os drivers ([SWS_Adc_00366], [SWS_Pwm_00096]). Chamadas concorrentes a partir de diferentes tarefas de OS devem ser protegidas por áreas exclusivas SchM (AUTOSAR_SWS_WatchdogDriver p. 11).

Notificações sobre eventos (por exemplo, transição de borda ou fim de conversão) são disparadas a partir do contexto de interrupção (ISR) através de callbacks configuráveis como Pwm_Notification_<#Channel> ([SWS_Pwm_00105]) ou Adc_Notification_Group_<x> ([SWS_Adc_91003]). Na ativação de notificações, flags de interrupção pendentes são resetadas ([SWS_Pwm_91004]). Se múltiplos grupos ADC concorrerem por recursos de conversor, atua, dependendo da configuração, uma priorização por hardware ou um enfileiramento por software (queuing) ([SWS_Adc_00522]) com mecanismo configurável de abort/restart ou suspend/resume ([SWS_Adc_00523], SWS_ADCDriver p. 97).

Ciclos de vida típicos e modos de operação

O ciclo de vida dos drivers MCAL começa na fase de inicialização de todo o sistema sob o controle do EcuM (SWS_ECUStateManager p. 34). Por meio de regras do BswM, uma ordem determinística é imposta: primeiro, Port_Init inicializa as funcionalidades de pinos (ModemanagementGuide p. 54). Somente depois seguem os drivers de periféricos como Dio_Init, Spi_Init, Adc_Init ([SWS_Adc_00365]), Pwm_Init ([SWS_Pwm_00095]) e Wdg_Init ([SWS_Wdg_00106], AUTOSAR_CP_SWS_PWMDriver p. 47).

Em operação, Wdg reconhece três modos estáticos: WDGIF_OFF_MODE, WDGIF_SLOW_MODE e WDGIF_FAST_MODE ([SWS_Wdg_00107]). O módulo Adc distingue conversões One-Shot e Continuous ([SWS_Adc_00515]), bem como modos de acesso Single e Streaming ([SWS_Adc_00528], [SWS_Adc_00519]). O status do grupo passa pelos estados ADC_IDLE, ADC_BUSY, ADC_COMPLETED e ADC_STREAM_COMPLETED ([SWS_Adc_00513], [SWS_Adc_00374], SWS_ADCDriver p. 37).

Para modos de economia de energia (Low Power), Adc e Pwm implementam um protocolo padronizado de Power-State bifásico: primeiro, Adc_PreparePowerState ([SWS_Adc_00478]) e Pwm_PreparePowerState ([SWS_Pwm_00183]) preparam a transição ([SWS_Pwm_00165], [SWS_Adc_00527]). Após a conclusão assíncrona, a abstração de hardware reporta a prontidão através de callbacks como IoHwAb_Adc_NotifyReadyForPowerState<#Mode> ([SWS_Adc_00480]). Finalmente, Adc_SetPowerState ([SWS_Adc_00475]) e Pwm_SetPowerState ([SWS_Pwm_00166]) comutam o hardware para o estado de destino (AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57). O monitoramento cíclico é assegurado em tarefas por Pwm_Main_PowerTransitionManager ([SWS_Pwm_00189], [SWS_Pwm_00190]).

No shutdown ou reset do sistema, serviços de desinicialização como Adc_DeInit ([SWS_Adc_00366], AUTOSAR_SWS_ADC_Driver p. 76) e Pwm_DeInit ([SWS_Pwm_00096], AUTOSAR_SWS_PWMDriver p. 47) transferem as unidades para um estado de repouso seguro e desativam todas as interrupções.

Diagrama de sequência: Mudança assíncrona bifásica de Power-State no cluster MCAL via BswM e IoHwAb. Fontes: AUTOSAR_CP_SWS_IOHardwareAbstraction p. 57, [SWS_Adc_00478], [SWS_Pwm_00183], [SWS_Adc_00475], [SWS_Pwm_00166].

Tratamento de erros, rastreamento pelo DET e degradação

Os erros são estritamente separados em erros de desenvolvimento e de produção. Com o controle de desenvolvimento ativo, os drivers reportam chamadas antes da inicialização realizada ao Default Error Tracer (DET), por exemplo através de PWM_E_UNINIT ([SWS_Pwm_00177], [SWS_Pwm_00104]) ou ADC_E_UNINIT ([SWS_Adc_00476]). Parâmetros de ponteiro são verificados contra NULL, como em GetVersionInfo via ADC_E_PARAM_POINTER ([SWS_Adc_00376]) e WDG_E_PARAM_POINTER ([SWS_Wdg_00109]).

Erros de tempo de execução asseguram contra transições operacionais inadmissíveis: se Pwm_SetPowerState for chamado enquanto canais não estiverem no estado IDLE ou ainda houver notificações ativas, o driver reporta o erro de tempo de execução PWM_E_NOT_DISENGAGED ([SWS_Pwm_00202]). No caso de Adc, a tentativa de disparar novamente um grupo de canais ocupado em configurações sem queuing leva ao relato de tempo de execução ADC_E_BUSY ao DET (SWS_ADCDriver p. 95).

Erros graves de produção e falhas de periféricos são reportados ao Diagnostic Event Manager (DEM) via Dem_SetEventStatus ([SWS_Wdg_00111]). Para a degradação em modos de emergência, Pwm_SetOutputToIdle disponibiliza a desativação imediata de saídas PWM individuais ([SWS_Pwm_91002]). No driver de watchdog, a definição do timeout de trigger para o valor 0 permite a parada imediata do servicing e força um reset oportuno da ECU ([SWS_Wdg_00155], [SWS_Wdg_00136], SWS_WatchdogDriver p. 29).
