6 Installing the software and setting up the hardware

The latest version of the Motor Control GUI is designed to run on any Windows 10, Windows 8, Windows 7, Vista, or XP-based operating system. To install the software, go to www.nxp.com/analogtools and select your kit. Click on that link to open the corresponding tool summary page. Look for “Jump Start Your Design”. Download the Motor Control GUI software to your computer desktop (LVMC-Steppermotor- setup.exe).

Run the installed program from the desktop. The Installation Wizard guides 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 then click the NXP icon. The Motor Control Graphic User Interface (GUI) appears. The GUI is shown in Figure 3. The hex address numbers at the top are loaded with the vendor ID for NXP (0x15A2), and the part ID (0x138). The panel on the left side displays these numbers only if the PC is communicating with the FRDM-KL25Z via the USB interface.

6.2 Step-by-step instructions for setting up the hardware using Motor Control GUI

When using the board make sure that the following operating parameters are followed or damage may occur.

• The maximum motor supply voltage (VM) cannot exceed 7.0 V, and must be at least

3.3 V

• The nominal operating current of the stepper motor cannot exceed 1.0 A (1.4 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). Switch to the other USB port (programming port) on the FRDM-KL25Z, and back after you load the project.

2. Go to the NXP page on mbed.org and look for the repository named "LVHB Stepper

Motor Drive" (https://developer.mbed.org/teams/NXP/code/LVHB-Stepper-Motor-

Drive-v2).

3. Import main.cpp source code into compiler.

4. Save the compiled code on your local drive, and then drag and drop it onto the mbed

drive (which is the FRDM-KL25Z) while connected to the programming OpenSDA port. Move the USB connector back to the other USB port on the FRDM-KL25Z. Note: Create a user before you can download the code. Connect the board 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 board.

5. Ready the computer and install the Stepper Motor Driver GUI software.

6. Attach DC power supply (without turning on the power) to the VM and GND terminals.

7. Attach one set of coils of the stepper motor to the OUT1A and OUT1B output

terminals. Attach the other phase coil of the stepper motor to terminals OUT2A and OUT2B. Launch the Stepper Motor Driver GUI software.

8. 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 lefthand 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.

9. Turn on the DC power supply.

10.Select Enable Target on the GUI. The demo is now ready to run.

11.Select Direction, Step Mode, and Acceleration Enabled.

Acceleration enabled controls motor speed slowly increasing from stop to maximum number of steps selected by Step Time slider control.

12.Click Run to run the motor. Notice that some options of the GUI are disabled while

the motor is running. To make changes, click Stop on the GUI, make the desired changes, and then click Run on the GUI to continue.

13.When finished, click Enable Target on the GUI, and then Quit. Turn off DC power

supply. Remove USB cable.

6.3 Installing CodeWarrior

This procedure explains how to obtain and install the latest version of CodeWarrior (version 10.6 in this guide).

Note: The sample software in this kit requires CodeWarrior 10.6 or newer. The component and some examples in the component package are intended for Kinetis Design Studio 3.0.0. If you have CodeWarrior 10.6 and Kinetis Design Studio 3.0.0 already installed on your system, skip this section.

1. Obtain the latest CodeWarrior installer file from the NXP CodeWarrior website: http://

www.nxp.com/CODEWARRIOR.

2. Run the executable file and follow the instructions.

3. In the Choose Components window, select the Kinetis component, and then click

Next to complete the installation.
