Introduction to PCB
The DRV8711EVM is a complete solution for evaluating the DRV8711 stepper motor controller. It includes
a MSP430F2617 to control the DRV8711. Power is provided externally, up to 52 V, through the power
header. The USB interface is provided to communicate with the MSP430F2617 through a graphical user
interface (GUI).
The DRV8711EVM is configured such that only connections to the universal serial bus (USB), motor and
power supply are required.
2.1
Connectors
The DRV8711EVM uses a combination of headers for the application and monitoring of power. For the
EVM, a single power supply rail is necessary. The minimum recommended input voltage (VM+) for the
EVM is 8 V and the maximum recommended input voltage is 52 V. Please see the DRV8711 datasheet
for the complete voltage range information of the driver. When the USB is connected to the board a red
LED (D3) in the lower left corner begins blinking.
Power for the DRV8711 is available through connector J1. The J1 connector is located on the top right
corner of the EVM.
The motor connections are provided through connectors J2 and J3. Connectors J2 and J3 are located on
the lower right of the EVM.
The USB connection (J5) is located on the upper left of the EVM. It is used to connect the PC to the EVM.
The GUI is used to control the stepper motor.

Test Points
Test points are provided and labeled according to the inputs and outputs of the DRV8711 motor driver.
Test points are also provided to observe the power FET signals.
2.3
Jumpers
There are two jumpers (JP1 and J6) on the EVM that are normally installed.
Jumper JP1 is used to reprogram the MSP430F2617, it is normally connected from JTAG to the center
pin. JP1 is not required for operation and may not be installed.
Jumper J6 contains a row of 13 jumpers connecting the MSG430F2617 to the DRV8711 inputs and
outputs. This allows the MSP430F2617 to control the DRV8711 through the supplied GUI.
For normal operation right out of the box all of the jumpers of J6 should be installed. The jumpers can be
removed to isolate the microcontroller (MCU).
If a signal is to be interfaced externally, the signal can be attached to either the test stakes or the driver
side of J6.

DRV8711 EVM GUI Overview
The DRV8711 EVM GUI application is the software counterpart for the DRV8711 EVM. It allows the PC to
connect to the MSP430F2617 MCU through a USB interface chip. Once the connection is established,
and commands are sent, the MCU takes care of configuring control signals, running the stepper through
acceleration and deceleration profiles, sending serial peripheral interface (SPI) data packets and pulsewidth modulation (PWM) generation, and so forth.
The GUI is designed to allow testing without hardware intervention for all of the DRV8711 device
functionality. Figure 23 shows the DRV8711EVM High-Level Page.

On DRV8711, most of the control signals are available through internal SPI registers. Easy access to
these SPI registers is spread among three different tabs in the High-Level Page. Control signals such as
nSLEEP, DIR and RESET are available throughout the High-Level Page. A simple SPI frame is provided
in High-Level Page in case the user wants to send particular SPI packets to the available registers.
The Low-Level Page is used to write the values directly into the registers. The Low-level Page has the
representation of the Register map which makes the user easier to write the values for each bit in a
register.

This frame allows the configuration and running of the stepper with the direction specified by the DIR
command button, and the other parameters such as current, decay mode, and micro-stepping resolution,
is set by writing to their respective SPI registers. The motion control frame gathers user information
regarding stepping rate or motor speed. An acceleration profile is employed to start at a programmable
speed and increase stepping rate until reaching the programmable desired speed.
An internal 8-MHz timer is used to measure time and generate the steps in a timely manner. The Windows
application transforms the entered number of PPS into the respective clock cycles needed for the timer to
produce accurate STEP pulse timing.
The acceleration profile is coded inside of the MCU to accept both the Start Speed pulse per second
(PPS) and Target Speed PPS as a clock cycle number. When the Start Steps command is issued (by
pressing the Starts Step button), an Interrupt Service Routine (ISR) generates steps at a rate specified by
the Start Speed PPS parameter.
The very same Starts Step command computes how frequent automatic speed updates are issued and a
second timer is used to change the speed according to the programmed acceleration rate profile.
Once the Target Speed PPS is reached, the acceleration profile ends, and the motor stays running until
the Stop Stepper command is issued (by pressing the Stop Stepper button). When the stepper is
commanded to stop, the controller does as it did while accelerating, but in reverse to achieve deceleration
until the Stop Speed PPS is reached, in which case the motor fully stops.
A second motor actuation is provided by the Move Steps command in which a programmed number of
steps are issued and then the motor is stopped. The acceleration and deceleration profiles work similarly
as before, except when the deceleration starts to happen and when the motor actually stops are a function
of the Steps to Stop and Deceleration Rate parameters. The below Figure shows the acceleration profile
the role each parameter plays during speed computation.

Start Speed PPS—Number of pulses per second (or full steps per second) at which the motor rotates
at the beginning of an operation. The SW only allows a number as small as 200 PPS and can be taken
to a number as large as 65535 PPS.
Target Speed PPS—Number of desired pulses per second (or full steps per second) at which the
motor operates. The acceleration profile starts from the Start Speed PPS and increases stepping rate
until reaching the Desired Speed PPS. The SW only allows a number as small as 200 PPS and can be
taken to a number as large as 32000 PPS.
Acceleration Rate (0-5000)— A number from 0 to 5000 which acts as a stepping rate modifier to
increase the Start Speed PPS up to Target Speed PPS.
Stop Speed PPS—Number of pulses per second (or full steps per second) at which the motor stops
rotating after the Stop Stepper command is invoked, and the deceleration profile is issued. The
deceleration profile modifies the stepper speed from the Target Speed and into the Stop Speed. If the
user desires to move the stepper a certain number of steps, this can be easily accomplished by using
the Move Steps function. Parameters from the other frames are reused, and its utilization is as
previously explained. Two new parameters have been added to control the limited number of steps
actuation properly.
Number Of Steps—How many steps the controller issues.
Steps To Stop—The controller is continuously monitoring the step being issued, and when the current

step is equal to the Steps To Stop parameter, a deceleration profile is issued. If Steps To Stop is larger
than the Number Of Steps, then the motor stops abruptly without undergoing a deceleration profile.
When a deceleration profile is issued, the controller decreases the speed until reaching the Stop
Speed value. If the Number Of Steps parameter is met before the deceleration profile is complete, then
the motor stops at the current speed. If the Stop Speed is fulfilled before all the Number of Steps are
issued, then the motor rotates at the Stop Speed value until all the steps are executed. Ideally, the
system must be tuned to resemble a case in which the controller executes all the commanded steps at
speed as close as possible to the Stop Speed. In the event this is not feasible, due to the particular
parameters being chosen, stopping the motor at speed very close to the Stop Speed is often good
enough to ensure proper motion quality and application performance.

•
Register Read and Write
– Write Selected – When Write selected is clicked, the register which is chosen will be written by its
value, and the Field view will also be updated.
– Write Modified – When Write Modified is clicked, all the values of the registers which are modified
will be written to the respective registers, and the Field view will also be updated.
– Read Selected - When the Read Selected button is clicked, the value will be read from the device
for the register which is chosen. The field view will also be updated with the values.
– Read All – When Read All is clicked, the data is read from all the registers. The field view will also
be updated with the values.
Figure 36. Low Level Page Operations
NOTE: The low level page will allow the user to only read/write the selected field/register, for
example, it provides an abstract of the device's registers and not additional functionality
associated with them.
The operation/functionality linked to a field/register other than the read/write operations is
only handled in the high level page.

Open Configuration
– If this option is clicked, it loads the configuration file which was saved earlier to bring the device to a
known state.
– Load Config will overwrite the existing data in registers with the value specified in the .cfg file
loaded.
Save Configuration
– If this option is clicked, the current register configuration will be saved into a file which can be later
loaded into the GUI using the Load option.
Preferences
– Show Dialog? - If this option is selected, if the user modifies some register value and changes the
update mode to the “Immediate” then the user will be prompted with the dialog to take action for the
modified values. If this option is not selected, then the user will not be prompted with the dialog the
action will be based on Write Modified?

Script
•
•
•
•
Scripting is used to automate the device operations and reduces the time consumption in repeating
similar operations.
This is helpful in situations where performing a particular device function may require setting 10 to 15
registers on the device to a particular value. In these circumstances, scripts could be recorded and run
whenever needed.
In DRV8711 GUI, the scripting is done using Python because
– It’s easier to implement
– More widely used
– More user-friendly
Recording and Running Scripts
– Selecting the Launch Window again will open another untitled window, and the one opened last will
be active.
– The python window captures predefined actions only. While recording, no action has to be
performed on the python window such as moving the cursor, entering data, and so forth
– Start Recording - To start recording
• Go to Scripts -> Launch Window in the DRV8711 GUI.

In GUI window, traverse to the Scripts -> Start Recording option in the menu.
This opens an untitled, empty Python window in IDLE IDE.
