Page 2: Scope Of Work
An ASCLIN module is configured as LIN master to send “Hello World!” The string “Hello World!” is sent via an ASCLIN module configured as LIN master. The signal can be visualized using an oscilloscope. 2019-10-17 Copyright © Infineon Technologies AG 2019.

Page 4: Hardware Setup
Hardware setup This code example has been developed for the board KIT_AURIX_TC297_TFT_BC-Step. The port pin P15.5 (LIN-TX/RX) should be connected to an oscilloscope probe. TX/RX Ground 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved. - Page 5 The pin configuration is set using the predefined structure IfxAsclin_Lin_Pins. The ASCLIN module is initialized with IfxAsclin_Lin_initModule(). All functions required for the configuration of the ASCLIN module are provided by the iLLD header IfxAsclin_Lin.h. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
- Page 6 The transmission of header is checked by using the parameter txHeaderEnd of the structure acknowledgmentFlags. The frame is sent with the function IfxAsclin_Lin_sendResponse(). The functions above are provided by the iLLD header IfxAsclin_Lin.h. 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved.
