Freescale Tower System

The TWR-K70F120M module is part of the Freescale Tower System, a modular

development 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 peripheral modules, including the new TWR-LCD-RGB

which accepts RGB data from the K70 MCU graphics LCD controller.

Step-by-Step Installation Instructions

Install 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.

Configure 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.

Tilt 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.

Play the

Memory Game

Press SW2 to play a memory recall

game using the touch pads E1–E4.

A sequence will light up, then press

the touch pads 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.
