I wish to connect a serial device (WIFI Module) to the K22F board. If I am reading the schematic correctly, my best option is to use UART_2 on the J3 port. I cannot find any documentation or examples that do not use "mbed.h" and that file is not available. I am using Kinetis Design Studio Version: 3.2.0. I want to be able to still use the Debug UART as that is working properly.
What are my options for connecting an external module? Is there a way to add "mbed.h" to KDS? Links to applicable documentation is appreciated.
