i am using frdmk64f120 controller. am working on KDS 2.0 and KSDK 1.0.0 mqx examples.
i need uart-3 port interrupt receive and transmit function.
UART-3 RX/TX pin- PTC16 AND PTC17. SO can any one tel how to initialize and how to make code for this one..? please give explanation of code also. already i saw "hello" example code but i didn't understood how they are initialized and how they are using. if i call " printf " function its printing string but i didn't understand which function they are calling and used.
i am not expert in coding so give example code simple way to understand.
