How can I use serial communication using KL27Z?

[tiagobmarinho]

How can I use serial communication?

Which ports could I use and how can I use? Lines, library, all.
Both serial ports that the manual explain works, but isn't functionally for me, because I can't save or send the data that have been sent or wrote.

I didn't found any program or help in other documents/this community.

I hope that someone could help me, thanks!

Hi Tiago,

Considering that you have download the SDK v2 in your last question.
Please test these examples on your FRDM-KL27Z board.

Best Regards,

Robin

Hi Tiago

UART: http://www.utasker.com/docs/uTasker/uTaskerUART.PDF

KL27 has 1 UART and 2 LPUARTs: http://www.utasker.com/kinetis/UART_LPUART.html

For the pins that can be multiplexed, check chapter "Signal Multiplexing and Signal Descriptions" of the user's manual
