FRDM-KL25Z serial communication

Serial demo program for the FRDM-KL25Z board. UART0 is used for communication via OpenSDA's USB-UART protocol converter. Default speed and format are used: 9600 bps, 8-bit, no parity, 1 stop bit.

Usage: Find your virtual serial port at your computer and watch the transmission by using a terminal application. When you send a character from the PC, the character will be echoed back and the character code (in decimal) will be printed as well.

Hardware requirements:

  • FRDM-KL25Z board
  • USB cable between the PC and the OpenSDA connector
