Hi @annappa
Example codes using low-level drivers (IP) and high-level drivers (MCAL) are provided with the RTDs. These examples are named Flexio_Sent_Ip_Receiver_S32K3xx and Sent_Receiver_S32K3xx (where xx refers to the specific derivative). They are available for the following devices: S32K396, S32K344, S32K358, S32K388, and S32K389.
If you are using S32 Design Studio (S32DS), you can create a project directly from an example (HOWTO: S32 Design Studio - Create a New S32DS Project from Example). For EB Tresos, you can find the examples in a path similar to the following:
C:\NXP\SW32K3_S32M27x_RTD_R21-11_6.0.0\eclipse\plugins\Sent_TS_T40D34M60I0R0\examples\EBT
