FRDM-KL25Z Freedom Development Platform
4 FRDM-KL25Z Freedom Development Platform
The Freescale Freedom development platform is a set of software and hardware tools for evaluation and development. It is ideal for rapid
prototyping of microcontroller-based applications. The Freescale Freedom KL25Z hardware, FRDM-KL25Z, is a simple, yet sophisticated
design featuring a Kinetis L Series microcontroller, the industry's first microcontroller built on the ARM®Cortex™-M0+ core.
4.1 Connecting FRDM-KL25Z to the Board
The FRDM-17C724-EVB kit may be used with many of the Freedom platform evaluation boards featuring Kinetis processors. The
FRDM-KL25Z evaluation board has been chosen specifically to work with the FRDM-17C724-EVB kit because of its low cost and features.
The FRDM-KL25Z board makes use of the USB, built in LEDs, and I/O ports available with Freescale’s Kinetis KL2x family of
microcontrollers. The main functions provided by the FRDM-KL25Z are to allow control of a stepper motor using a PC computer over USB,
and to drive the necessary inputs on the FRDM-17C724-EVB evaluation kit to operate the motor.
The FRDM-17C724-EVB is connected to the FRDM-KL25Z using four dual row headers. The connections are as follows:

5 Installing the Software and Setting up the Hardware
5.1 Installing the Motor Control Graphical User Interface (GUI) on your
Computer
The latest version of the Motor Control GUI is designed to run on any Windows 8, Windows 7, Vista, or XP-based operating system. To
install the software, go to www.freescale.com/analogtools and select your kit. Click on that link to open the corresponding Tool Summary
Page. Look for "Jump Start Your Design". Download to your computer desktop the Motor Control GUI software.
Run the install program from the desktop. The Installation Wizard will guide you through the rest of the process.
To use the Motor Control GUI, go to the Windows Start menu, then Programs, then Motor Control GUI, and click on the Freescale icon.
The Motor Control Graphic User Interface (GUI) will appear. The GUI is shown in Figure 3. The hex address numbers at the top are loaded
with the vendor ID for Freescale (0x15A2), and the part ID (0x138). The left side panel displays these numbers only if the PC is
communicating with the FRDM-KL25Z via the USB interface.

5.2 Configuring the Hardware
Figure 4 shows the configuration diagram for FRDM-17C724-EVB.
Figure 4. FRDM-17C724-EVB plus FRDM-KL25Z Board Setup
5.2.1 Step-by-step Instructions for Setting Up the Hardware Using Motor
Control GUI
When using the FRDM-17C724-EVB make sure that the following operating parameters are followed or damage may occur.
• The maximum motor supply voltage (VM) cannot exceed 5.5 V, and must be at least 3.3 V
• The nominal operating current of the stepper motor cannot exceed 0.4 A (0.8 A peak)
In order to perform the demonstration example, first set up the evaluation board hardware and software as follows:
1. Setup the FRDM-KL25Z to accept code from the mbed online compiler. mbed is a developer site for ARM based
microcontrollers. The instructions are at mbed.org (https://mbed.org/handbook/mbed-FRDM-KL25Z-Upgrade) (you will need
to switch to the other USB port on the FRDM-KL25Z, and back after you load the project).
2. Go to the Freescale page on mbed.org and look for the repository named "LVHB DC Motor Drive".
(http://developer.mbed.org/teams/Freescale/code/LVHB-Stepper-Motor-Drive/) Save the compiled code on your local drive,
and then drag and drop it onto the mbed drive (which is the FRDM-KL25Z). Move the USB connector back to the other USB
port on the FRDM-KL25Z. 
Note: You may be asked to create a user before you can download the code.
3. Connect the FRDM-17C724-EVB to the FRDM-KL25Z. This is best accomplished by soldering the female connectors to the
FRDM-KL25Z, and then connecting to the male pins provided on the FRDM-17C724-EVB.
4. Ready the computer, install the "Stepper Motor Driver GUI Software" (See Section 5.1).
5. Attach DC power supply (without turning on the power) to the VM and GND terminals.
6. Attach one set of coils of the stepper motor to the OUT 1A and OUT 1B output terminals. Attach the other phase coil of the
stepper motor to terminals OUT2A and OUT2B. Launch the "Stepper Motor Driver GUI Software".
7. Make sure the GUI recognizes the FRDM-KL25Z. This is determined by seeing the hex Vendor ID (0x15A2), and Part ID
(0x138) under USB connection in the upper left hand corner of the GUI. If the GUI does not recognize the FRDM-KL25Z, you
need to disconnect and reconnect the USB cable to the FRDM-KL25Z.
8. Turn on the DC power supply.

9. Click on the "Enable Target" checkbox on the GUI. The demo is now ready to run.
10. Click the "Run" button to run the motor. Notice that some options of the GUI are disabled while the motor is running. To
make changes, click the "Stop" button on the GUI, make the desired changes, and then click "Run" on the GUI to continue.
11. When finished, click "Enable Target" button on the GUI, and then "Quit". Turn off DC power supply. Remove USB cable.
