Loadable — the configuration parameter shall be of configuration class Post Build and only one configuration parameter set resides in the ECU.

This symbolic name allows accessing Channel data. In this case the priority handler should put the interrupted channel group conversion in the queue 23 of Document ID C16x Derivate Wording Software triggered one-shot conversion where the converted group consists of exactly one channel.

The group channel values are stored in ascending channel number order in contrast to the storage layout of the result buffer if streaming access is configured. No priority mechanism — no queuing 81 of Document ID Cyclic conversion of a single channel.

Results of previous conversion rounds which are already written to the result buffer are not affected. The mixed hardware and software prioritization mechanism AdcPriorityHwSw uses the ADC hardware features for prioritization of ADC hardware trigger for groups with trigger source hardware and a software implemented prioritization mechanism for groups with trigger source software.

Returns the conversion status of the requested ADC Channel group.

Function called while maximum number of available hardware triggers is already enabled. We intend to leave Chapter Continuous conversion mode only available for software triggered ews.

Error detection 43 of Document ID Its allocation is described in below image. Design Stage Uncertainty Problem.

The ADC module supports the following start conditions or trigger sources: Note that these parameters do not have any configuration class setting, since they are published information. This file shall contain all post-build time configurable parameters. If development error detection for the ADC module is enabled and the priority mechanism is disabled and the queuing is enabled: Result of serial communication test visualized in Hyper Terminal.

LSB first Space configuration between successive bytes: If the hardware allows for only one usage of the register, the driver module implementing that functionality is responsible for initializing the register. Diversity can mean Survival. The switch AdcDevErrorDetect see chapter The information about number of channels belonging to the group and number of samples acquired per channel can be derived from the group configuration data.

Requirement for documentation not for module specification. The module shall optionally include the Dem. Disables the hardware trigger for the requested ADC Channel group.

Specification of ADC Driver

Requirement on implementation, not on specification. The group priorities for software triggered groups are typically configured with lower priority levels than the group priorities for hardware triggered groups. Values for production code Event Ids are assigned externally by the configuration of the Dem. It provides services to start and stop a conversion respectively to enable and disable the trigger source for a conversion.

This value will be assigned to the symbolic name derived of the AdcChannel container shortName. If autosad error detection ssw the ADC module is enabled and the priority mechanism is enabled: Development error values are of type uint8.

Trigger source HW is not available for continuous conversion mode.

Specification of ADC Driver

Keep in mind that the developers of the C-code often have no access or license to the Configuration-Tool-Chain. Link time Label x — – – specifies whether the configuration parameter shall be of configuration class Post Build or not Description The configuration parameter shall be of configuration class Post Build and no atosar implementation is required.

It contains internal device drivers with direct access to micro- controller and peripherals.

To correct this error, reconfiguring LIN module to proper bit sampling point is required. Depending on the group configuration, one-shot or continuous conversion is started. Software triggered continuous conversion with notification Figure The states are group specific and not module specific.

The read values shall be right-aligned.

Type of assignment of channels to a channel group this is not an API type. Multiple — the configuration parameter shall be of configuration class Post Build and is selected out of a set of multiple parameters by passing a dedicated pointer to the init function of the module. Groups which can be implicitly stopped are: If hardware priority mechanism is supported and selected: If single access mode is selected one sample of each group channel is held in the buffer.

See arxml snippet above. The specific implementation of the ADC module describes restrictions concerning the available hardware priority levels and the possible mapping autsoar the available hardware priorities to the priorities of the ADC channel groups. Returns the version information of this module. One-time writable adcdrivre that require initialization directly after autowar shall be initialized by the startup code. Replacement mechanism, which is used on ADC group level, if a group conversion is interrupted by a group which has a higher priority.
