4.16.2. Introduction

SENT stands for Single Edge Nibble Transmission. The SENT protocol is unidirectional and uses single wire between two or more points to transmit signals from one or more sensors to a controller. This protocol can transmit high resolution data at a low cost to the system. The SENT module utilizes a Master Trigger Pulse Generator to control and receive data from one or more sensors, using a configurable pulse signal. The received data can be stored directly into memory or a FIFO and read by the CPU or RTDMA.

SENT driver is part of complex device drivers which receive the data from the sensors and send the RX indication, support both fast channel and slow channel.

4.16.3. Functional Overview

F29X supports two modes of the SENT :

Standard SENT:

  • This supports only one sensor per the instance.

  • Sensors will be automatically sends the data, no triggering required from the ECU/coordinator.

MTP ( Master Trigger Pulse ):

  • This supports up to 4 sensors + broadcast.

  • Sensors sends the data only after master triggers the corresponding pulse of the sensor.

  • For triggering the pulse, there are 10 comparators which can be configured to different pulse widths.

Sent Integration with AUTOSAR Communication stack Sent is communication protocol implemented in the Cdd Sent driver. Similar to other communication protocols such as Can/Lin/Flexray, Sent can also be integrated with AUTOSAR communication stack. Cdd Sent is a driver. This driver can directly act as a lower layer module for PduR without needing an interface layer in between. Integration of Cdd Sent driver with AUTOSAR com stack is optional and can be enabled by configuration parameter CddSentIntegrationWithAsrComStackEnable. When it is enabled, Cdd Sent driver is responsible to call the receive indication to PduR and PduR is responsible to call transmit function to Cdd Sent. In order to achieve this, correct handle Ids should be configured in both Cdd Sent and PduR. Please refer to the explanation of Cdd_Sent_Transmit() and PduR_Cdd_Sent_RxIndication() in Cdd Sent driver.

4.16.9. Integration description

4.16.9.1. Dependent modules

4.16.9.1.1. PduR

The PDU Router module provides services for routing of routing Protocol Data Units(I-PDUs) between various communication modules, ensuring seamless data transfer across different communication protocols.When the Cdd_Sent module receives sensor data, it encapsulates the data into PDUs and sends them to the PduR with PDU id’s. The PduR then routes these PDUs to the appropriate higher-layer modules. User need to configure configure PDUs in ECUC. Cdd_Sent will generate symbolic names for those PDUs in Cdd_Sent module.

Note

  • Symbolic names are used to call PduR receive indication.

  • Symbolic name template follows : “PduRConf_PduRSrcPdu_PduRSrcPdu_{PduName}”

    • PduName is the symbolic name configured in EcuC->Pdu Container.

    • PduRSrcPdu_PduName must be the name of source PDU configuration container in PduR routing table.[As a result PduR will generate symbolic name “PduRConf_PduRSrcPdu_PduRSrcPdu_PduName”]

4.16.9.1.2. DET

This implementation depends on the DET in order to report development errors. The detection of development errors is configurable (ON / OFF), The switch CDD_SENT_CFG_DEV_ERROR_DETECT will activate or deactivate the detection of all development errors.

4.16.9.1.3. DEM

This implementation depends on the DEM in order to report Extended production errors and can be turned OFF. The switch CDD_SENT_CFG_DEM_ENABLE will activate or deactivate the detection of all extended production errors. If hardware failure notification is enabled in the configuration set and a hardware source failure error occurs, the error code CDD_E_HARDWARE_ERROR shall be reported.

4.16.9.1.4. MCU

MCU Module is required to initialize all the clock to be used by different peripherals.

4.16.9.1.5. Port

The Port module configures the port pins used for the SENT driver as input. Hence, the Port driver has to be initialized prior to the use of SENT functions. Otherwise Cdd_Sent driver functions will exhibit undefined behavior.

4.16.9.1.6. OS

The Cdd_Sent driver uses interrupts and therefore there is a dependency on the OS, which configures the interrupt sources.

4.16.9.2. Resource Allocator

The SENT module references the Resource Allocator for device, package, and variant configuration. See the Resource Allocator Module User Guide for details on configuring device-specific settings.

4.16.9.2.1. Resource Allocator Usage Example

To allocate SENT1 to CPU1 using FRAME0:

  1. In the Resource Allocator configuration, create a new Sent instance allocation

  2. Set InstanceName to SENT1

  3. Set Frame to FRAME0

  4. The BaseAddr will be automatically calculated as SENT1_DRIVER_BASE_FRAME(0U)

Resource Allocator Configuration:
├── SentInstanceAllocation
│   ├── InstanceName: SENT1
│   ├── Frame: FRAME0
│   └── BaseAddr: SENT1_DRIVER_BASE_FRAME(0U)

4.16.10. Configuration

The Cdd_Sent Driver implementation supports one configuration variant Pre-Compile config. The driver expects generated Cdd_Sent_Cfg.h to be present as input file. The associated Cdd_Sent driver configuration generated source files are Cdd_Sent_Cfg.c

The generated configuration files should not be modified manually. The config tool Elektrobit Tresos should be used to modify the configuration files.

4.16.10.1. Migration Guide

Migration guides between module versions are detailed below.

4.16.10.1.1. v3.0.0 from v2.0.0

This section describes the changes required when migrating from CDD SENT driver version 2.0.0 to version 3.0.0.

4.16.10.1.1.1. Key Changes

  1. Resource Allocator Based Approach

    • The CDD SENT module now uses the Resource Allocator for device, package, and variant configuration

    • SENT instance selection is now done through CddSentInstanceRef which references the Resource Allocator’s allocated instances

    • Base address (CddSentBaseAddress) is automatically derived from the Resource Allocator configuration

    • See the Resource Allocator Module User Guide for details on configuring device-specific settings

  2. DEM Configuration Parameter Name Change

    • The DEM event parameter reference name has been changed for consistency with module naming conventions

    • Old name: CDD_E_HARDWARE_ERROR

    • New name: CDD_SENT_E_HARDWARE_ERROR

4.16.10.1.1.2. Migration Steps

  1. Update Resource Allocator Configuration

    • Configure the Resource Allocator module with the required SENT instances

    • Allocate SENT instances to the appropriate CPU context

  2. Update CDD SENT Configuration

    • Open the CDD SENT module configuration in EB Tresos

    • For each CddSentController, set the CddSentInstanceRef to reference the appropriate allocated instance from Resource Allocator

    • The CddSentBaseAddress will be automatically populated based on the Resource Allocator configuration

  3. Update DEM Configuration References

    • If DEM error reporting is enabled, update the DEM event parameter reference

    • Change references from CDD_E_HARDWARE_ERROR to CDD_SENT_E_HARDWARE_ERROR

    • Update any application code that references this DEM event parameter name

  4. Regenerate Configuration

    • Save the configuration and regenerate the configuration files

  5. Rebuild Application

    • Rebuild your application with the updated configuration

4.16.10.1.2. v2.0.0 from v1.0.0

To align with AUTOSAR CDD naming convention, we have named Module Name as Cdd and apiServicePrefix as Cdd_Sent. This results in change in schema as described below.

To make v1.0.0 Sent schema(generated .xdm file) compatible with v2.0.0 below changes are required:

  1. Change ‘AR-ELEMENT’ name from Cdd_Sent to Cdd.

  2. Update MODULE-CONFIGURATION path from ‘ASPath:/TI_F29H85x/Cdd_Sent’ to ‘ASPath:/TI_F29H85x/Cdd_Sent/Cdd’.

Earlier schema:
<d:lst type="TOP-LEVEL-PACKAGES">
<d:ctr name="Cdd_Sent" type="AR-PACKAGE">
<d:lst type="ELEMENTS">
<d:chc name="Cdd_Sent" type="AR-ELEMENT" value="MODULE-CONFIGURATION">
<d:ctr type="MODULE-CONFIGURATION">
<a:a name="DEF" value="ASPath:/TI_F29H85x/Cdd_Sent"/>

Modified new schema:
<d:lst type="TOP-LEVEL-PACKAGES">
<d:ctr name="Cdd_Sent" type="AR-PACKAGE">
<d:lst type="ELEMENTS">
<d:chc name="Cdd" type="AR-ELEMENT" value="MODULE-CONFIGURATION">
<d:ctr type="MODULE-CONFIGURATION">
<a:a name="DEF" value="ASPath:/TI_F29H85x/Cdd_Sent/Cdd"/>

4.16.11.2.1. Overview of Cdd_Sent_Mtp_ExternalTrigger_Source

  • Cdd_Sent_Mtp_ExternalTrigger_Source

    • This example reads data from an MTP sensor with external trigger source using SENT communication protocol

    • Sensor details:

      • Product Type: TLE5014C16D

      • Marking: 014CD

      • Sensor Type: SPC Interface

    • The sensor sends out a signal made up of a string of pulses with data encoded as falling to falling edge periods

    • The modulated signal with constant amplitude voltage evaluates the time interval between two falling edges (a single edge) delivered in units of 4 bits (1 nibble), representing values from 0 to 15

    • This example configures SENT module to receive 4 Data-nibble per frame for fast channel

    • DeviceSupport_Init()

    • EcuM_Init()

      • Initialize clock using Mcu_Init()

      • Initialize pins with Port_Init()

      • Initialize Cdd_Sent driver using Cdd_Sent_Init()

    • Trigger sensor with Sent Handle ID using Cdd_Sent_Transmit()

    • Enable GPT notifications and start timer with 1s timeout

    • Wait for data reception and verify external trigger behavior

    • Stop timer and trigger sensor again

    • Receive and display data from fast and slow channels via callback

    • Deinitialize GPT and Cdd_Sent drivers

    • External Connections:

      • Connect GPIO18 to sensor’s SENT channel 4 pin
