Hi there, I am using KSDK1.2.0 with KDS 3.0.0 with FRDM-KL25Z board. I am trying to understand the purpose of the UART receive callback function when setting the parameters of UART in processor expert. In the callback function generated, there are 2 input parameters: uint32_t instance and void *uartState. How do i make use of these to obtain the received character in the UART?
