TOWER SYSTEM Step-by-Step Installation Instructions In this Quick Start Guide, you will learn how to set up the TWR-K40X256 module and run the default demonstration. STEP 1 Install the Software and Tools 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. STEP 3 Tilt the Board STEP Navigate the Segment LCD Tilt the board side to side to see the LEDs on E1–E4 light up as it is tilted. 4 STEP 2 Configure the Hardware 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. 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.
