Step-by-Step Installation
Instructions
In this Quick Start Guide, you will learn how to set up the TWR-K65F180M board and run
the included demonstrated software. For more detailed information, review the user manual
at
freescale.com/TWR-K65F180M.

Run the Quick
Start Demo
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/OpenSDA micro-
AB connector on the TWR-K65F180M
module. Allow the PC to automatically
configure the USB drivers if needed.
The LEDs on the board, D6 and D7, will
gradually illuminate as the board is tilted.
When rotated around the accelerometer’s
x-axis the orange LED (D7) will illuminate.
Similarly, the yellow LED (D6) will gradually
illuminate as rotated around the y-axis.
The actual accelerometer data is printed to
a terminal window via the UART module.
