Board:  FRDM-K22F

IDE:  KDS 3.2


I want to send a few bytes out UART-1 on the FRDM.

1200 baud, 7-bit, even parity, 1 stop bit (required by SDI-12 sensor interface).


I see no activity on the Tx Output at pin D14.

Error code is "8" or "BUSY"

However...I do see activity if I send a BREAK. 


Attached is my project.

It's very simple. 


What am I doing wrong?
