Encoder Peripheral Configuration
Map encoder peripherals in the Infineon AURIX model to peripheral registers in the MCU
Since R2024a
Description
View and edit the map of peripherals in the Infineon® AURIX™ model to the hardware peripherals.
Encoder block is developed based on GPT12 (general purpose timer) module available in the AURIX TC3x devices.
Using the Peripheral Configuration tool, you can:
View and edit the configuration parameters for the Encoder peripheral block.
Configure the module specific parameters in BrowserPeripherals
Encoder
. For more, see .Check for conflicts, if any between peripherals.
Open the Encoder Peripheral Configuration
In the Simulink toolstrip, go to Hardware tab and click Hardware Mapping.
