TWR-K70F120M Freescale Tower System
Development Board Platform
The TWR-K70F120M board is part of the Freescale Tower System, a
modular development board platform that enables rapid prototyping and tool
re-use through reconfigurable hardware. The TWR-K70F120M can be used
with a broad selection of Tower System controller boards, including the new
TWR-LCD-RGB which accepts RGB data from the K70 MCU graphics LCD
controller.

Installation Instructions
3Tilt the
Board
Tilt the board side to side to see the LEDs
on E1–E4 light up as it is tilted. While the
board is held flat, touch the pads on E1–E4
to toggle the LEDs.
4Play the
Memory Game
Press SW2 to play a memory recall game
using the touchpads E1–E4. A sequence
will light up, then press the touchpads in
the order flashed. If an incorrect sequence
is touched or too much time has elapsed,
all the lights will blink rapidly and the game
will reset.
Press SW1 to return to the accelerometer
demo.

Features
1Install the Software
and Tools
Install the P&E Micro Kinetis Tower toolkit.
The toolkit includes the OSJTAG and USB
to serial drivers. These can be found on the
DVD under Software.
2Configure the
Hardware
Install the included battery into the VBAT
(RTC) battery holder. Then, connect one
end of the USB cable to the PC and the
other end to the Power/OSJTAG mini-B
connector on the TWR-K70F120M module.
Allow the PC to automatically configure the
USB drivers if needed.
