Introduction
The DRV8818EVM is a complete solution for evaluating the DRV8818 micro-stepping, bipolar stepper
driver. It includes a USB link to provide easy control from a personal computer (PC), a MSP430
microcontroller that interprets serial commands from the PC and generates control signals to the driver
device, and the DRV8818 device with access to all signals for a complete evaluation.
1.2
Power Connectors
The DRV8818EVM uses a combination of terminal blocks and test clips for the application and monitoring
of power. The only power rail that the user must supply is VM for the device’s power stage. VDD for logic
levels is internally generated from the USB connection.
Users must apply VM (8 V to 35 V) according to data sheet recommended parameters.
1.3
Test Stakes
Every pin on the device has been brought out to a test stake. A label on the silkscreen identifies each
signal.

Jumpers
Two styles of jumpers are on the DRV8818EVM: two-pin jumpers and three-pin jumpers.
Users can configure three-pin jumpers independently from other two- or three-pin jumpers. However, twopin jumpers must all be closed or left open.

control the DECAY modes.
(b)
Motor Outputs
Users can connect the bipolar stepper motor into the DRV8818EVM in three ways: four-pin header (J2),
four-position terminal block (J3), or test clips. Each connection style offers identical connectivity to the
device’s output terminals. The recommended way, however, is to use the header or terminal block
because the test stakes traces are of low-current handling capability.

Windows Application
The DRV8818 Windows application is the software counterpart for the DRV8818EVM. This application is
in charge of connecting to the MSP430 microcontroller by an USB connection, which in turn selects the
proper logic state for the DRV8818 control signals.
The design of the graphical user interface (GUI) allows for all of the DRV8818 device’s functionality to be
tested without having to intervene with the hardware, except for the proper configuration of jumpers, when
necessary.
Figure 24 shows the DRV8818EVM.exe main screen. It contains menu items to configure and enable and
disable the serial port, frames with GPIO control for the DRV8818 Control Signals, Stepper Motor control
for start and stop and speed, and current and decay control through the MSP430 DACs.

Connecting the EVM
The GUI auto-detects the port to which the USB has connected on connection of the USB cable between
the EVM and an available port on your PC. This is displayed in the window. Click the Connect button. If
this does not work, possible sources of error are as follows:
• FTDI drivers were not installed properly and the FTDI-USB chip is not recognized. Check for
connection in Control Panel→System→Hardware→Device Manager→Ports for a valid connection.
• Close the GUI, and reopen it to properly identify the open port.
4.2
Initial Configuration
First, go into the File menu. Select File→Configure Parameters, and the following box displays:

Basic Configuration and Control Buttons
Whereas clicking the individual pins changes the state of the pins, you can also use the control boxes at
the bottom to change the state of the pins.
For example, click on the Full Step radio button in the bottom right corner of the highlighted box. What
happens to the picture on the top?
4.3.3
Current Control and Decay Modes
This set of boxes controls the reference current and the current decay modes once this current threshold
is reached.
• Decay Control: The slider allows you to control the voltage on the DECAY pin. This controls which
mode the device is in when the current is decreasing through the load on the falling edge of the
sinusoidal current. In FULL Step mode, this control does not apply. The table shows the modes as it
corresponds to the voltage applied on the DECAY pin. For example, a voltage less than 0.7 V fixes the
device in a Fast decay mode. A voltage greater than 2 V puts the device in a Slow decay more. A
voltage between 0.7 V and 2 V selects a mixed decay with a ratio of fast decay followed by slow decay
depending on the voltage set between 0.7 V and 2 V. This is easier to see on an oscilloscope capture.
• Current Control: This slider sets the voltage on VREF. The current displays on the screen based on
the following calculation:
Iref = Vref / 8 × Rsense

Motion Control
Constant Speed Mode:
• Starting Speed (PPS): The following discussion defines pulses-per-second or PPS. A pulse is a single
step in the logic table. This is not necessarily a mechanical step. If you change micro-stepping modes,
you must double this for the same speed (in 1/2 step), x4 for 1/4 step, and so on.
• Desired Speed (PPS): This is the final speed that the motor ramps to and holds, otherwise known as
the target speed.
• Acceleration Rate (PPSPS): This is how fast the device ramps from the starting speed to the desired
speed. This is also the deceleration rate once you pause stepping.
• Start Steps Button: Press this button to spin. Press it again to stop, or pause, spinning.
• Update Speed Button: While spinning, you can change the Desired Speed field and nothing will
happen until you click Update Speed.
Indexing Mode:
• # of Steps: In Full Step mode, this is the number of mechanical steps you want to take. For example,
if the motor on your bench has 200 steps in a revolution and you want to move one revolution, you
choose 200 steps. If you are in 1/2 step mode, you need to double this to 400 for a full revolution.
• Steps To Stop: When the number of steps taken achieves this point, the motor starts to decelerate at
the rate given in the Acceleration Rate field.
• Stopping Speed: After the steps in the Steps To Stop field is reached and the motor begins to
decelerate, the motor rotates at this speed (once it is reached) until the value in the # of Steps is
reached.
• Move Steps Button: Click this to begin indexing. Once indexing is complete, you can click it again to
repeat the cycle.
