Description

Add-On Required: This feature requires the Embedded Coder Support Package for Infineon AURIX TC3x Microcontrollers add-on.

View and edit the map of peripherals in the Infineon® AURIX™ model to the hardware peripherals.

Using the Peripheral Configuration tool, you can:

  • View and edit configuration parameters for EVADC peripheral block.

  • Configure the global parameters. To set the group peripheral, select peripheral in BrowserPeripherals EVADC . For more information, see Map Tasks and Peripherals Using Hardware Mapping.

  • Check for any conflicts between peripherals.

EVADC peripheral mapping

Open the EVADC Peripheral Configuration

  • In the Hardware tab, click Hardware Mapping.

Parameters

Global parameters > Global settings > EVADC module parameters

Set the voltage supply for EVADC module.

Global parameters > Global settings > Global limit setting profile

Specify the global limit for profile 0.

Specify the global limit for profile 1.

Global parameters > G#

Select to enable group start up calibration.

G# > Request queue #

Select one of these conversion modes:

  • One-shot — Select this option for a one-time analog-to-digital conversion after a software or hardware trigger event. In case of hardware trigger event, you must add another EVADC block with the block parameter Mode set to ADC Trigger to fill the queue input register. You must map these EVADC trigger and read blocks using Select read block parameter in the Group select tab in the Hardware Mapping tool.

  • Refill with trigger — Select this option to wait for either software or hardware trigger for analog-to-digital conversion. This mode automatically refills the queue input register and a valid queue entry waits for a trigger event to initiate conversion.

  • Refill with one time trigger — Select this option for perpetual analog-to-digital conversion of valid queue entries after a software trigger. This mode automatically refills the queue input register.

When you configure PWM block to trigger the analog-to-digital conversion in One-shot or Refill with trigger conversion modes, the block converts the channels sequentially. Each of the EVADC channels requires its own PWM trigger signal to complete the conversion.

Select queue priority for ADC conversion for group #.

Select slot start mode for ADC conversion for group #.

Select source of gating for ADC conversion request for group #. For more information on EVADC trigger signals, refer to EVADC Trigger Signals.

Select gating mode for ADC conversion request for group #.

Select trigger source for ADC conversion for group #.

  • Software-Block sample time —

  • Software-Trigger block —

  • GTM ADC trigger signal# —

Select trigger mode for ADC conversion.

Dependencies

To enable this parameter, set the Trigger source parameter to GTM ADC trigger signal#.

G# > Group limit setting profile
