STEP 1 Install the Software and Tools STEP Install the P&E Micro Kinetis Tower Toolkit to install the OSJTAG and USB-to-Serial drivers. These can be found on the DVD under Software. Tilt the board side to side to see the LEDs on E1–E4 light up as it is tilted. 3 Tilt the Board STEP 4 STEP Install the included battery into the VBAT (RTC) battery holder. Then plug in the included Segment LCD Tower Plug-In (TWRPI-SLCD) into the Touch/ SLCD TWRPI socket. Finally, connect one end of the USB cable to the PC and the other end to the Power/OSJTAG mini-B connector on the TWR-K40X256 module. Allow the PC to automatically configure the USB drivers if needed. 2 Configure the Hardware Navigate the Segment LCD The Segment LCD will come up displaying the seconds elapsed since boot-up. Press SW4 to toggle between viewing the seconds, hours and minutes, potentiometer percent, and temperature. Quick Start Guide for TWR-K40X256 TOWER SYSTEM Explore Further by Conducting Lab 1: TWR-K40X256 Quick Start Demo STEP 5 Explore all the features and capabilities of the pre-programmed demo by reviewing the lab document located at freescale.com/TWR-K40X256.
