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.
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

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.

Memory Game
Press SW2 to play a memory recall
game using the touch pads E1–E4.
A sequence will light up, then press
