COM channel printf - MK60DN512xxx10

carbon — Fri, 18 Dec 2015 10:58:31 GMT

Hello,

I have a MK60DN512xxx10, can someone please show me how to use "printf" and "scanf" from standard stdio.h over COM channel?

Right now I have two channels open, COM4 which is writing dots over and over and COM5 which does absolutely nothing.

Right now, I use semihosting - telnet when debugging, but I need a two way communication.

Hi Tomas,

Please refer to this post:

How to use printf() to print string to Console and UART in KDS2.0

Besides, you also can refer to the KSDK1.3.0, folder:C:\Freescale\KSDK_1.3.0\examples\twrk60d100m

These code are also using the printf from stdio.h

If you still have question, please contact me!

Have a great day,

Jingjing

Please note, the code is printf from the tower Kxx, not the ser board.

Hello Joice,

Please check you use which UART to transfer , for the TWR-k53 example , the TWR-k53 use the UART0(J27),

while the TWR-SER use the UART3 (when connected to the TWR-K53 ).

Hope it helps
