How to enable UART3 on TWR-K60D100M

yarannan — Tue, 17 Mar 2015 20:32:33 GMT

I am trying to modify a demo application on KDS 2.0 with KSDK 1.1.0. I only have twr-k60d110m and TWR-IND-IO. Am i being able to change

default setting to UART3? Does anyone know?

Hi Yaran

I can't help with the demos but if you want full flexibility using KDS you can look at µTasker Kinetis TWR-K60D100M support

1. Choose the UART to be used as follows (example of opening the interface on any channel (0..5) and sending a "Hello, World!" output.

TTYTABLE tInterfaceParameters;

tInterfaceParameters.Channel = 3; // 0, 1, 2, 3 ,4 or 5

tInterfaceParameters.ucSpeed = SERIAL_BAUD_115200;

tInterfaceParameters.Config = (CHAR_8 + NO_PARITY + ONE_STOP + USE_XON_OFF + CHAR_MODE);

tInterfaceParameters.ucDMAConfig = UART_TX_DMA;

SerialPortID = fnOpen(TYPE_TTY, FOR_I_O, &tInterfaceParameters);

fnWrite(SerialPortID, "Hello, World!", 13);

2. Fine tune the UART's pin multiplexing by choosing from a set of defines:

//#define UART0_A_LOW	// alternative UART0 pin mapping
//#define UART0_ON_B	// alternative UART0 pin mapping
//#define UART0_ON_D	// alternative UART0 pin mapping
//#define UART1_ON_C	// alternative UART1 pin mapping
//#define UART2_ON_E	// alternative UART2 pin mapping
//#define UART2_ON_F	// alternative UART2 pin mapping
//#define UART3_ON_B	// alternative UART3 pin mapping
//#define UART3_ON_F	// alternative UART3 pin mapping
#define UART3_ON_C	// alternative UART3 pin mapping
//#define UART4_ON_C	// alternative UART4 pin mapping
//#define UART5_ON_D	// alternative UART5 pin mapping

Hi Yaran Nan,

I don't know which demo are you using.

let's take hello_world_twrk60d100m as an example.

To modify the debug console output to UART3, you need just modify BOARD_DEBUG_UART_INSTANCE from 5 to 3.

This Macro is defined in line 43 in board.h.

hope it helps!

So hey guys thanks for helping me. I still dont know how, but i will try it later.
