Hardware setup This code example has been developed for the board KIT_AURIX_TC297_TFT_BC-Step. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved. - Page 5 Inside the function initPeripherals(), the port pin is configured to push-pull output mode using the function IfxPort_setPinMode(). During program execution, inside the interrupt service routine isrSTM(), the LED is switched on and off using the function IfxPort_setPinState(). 2019-10-17 Copyright © Infineon Technologies AG 2019.
