Hi, 

the example is part of EAR SDK v0.8.2. Check if you have installed all updates (Help -> Install New Software). With updated S32DS - you can find example here:

Hello, 

On MPC5744P is not I2C hardware module present. If you can't use other interface (SPI, CAN, UART) - you have to implement your own software i2c by using GPIO pins.
