Jumpers
There are two styles of jumpers on the DRV8821-23EVM: two pin jumpers (JP3 and JP4) and three pin
jumpers (JP1 and JP2).
Two pin jumpers are used to set AB DECAY or CD DECAY HI or LO.
Three pin jumpers are used to select the VREF from a pot or from the microcontroller’s DAC outputs.

To configure the VREF select (either AB or CD) jumper, (a) Use position JPx-1:2 to select the MSP430
DAC output (default). (b) Use position JPx-2:3 to select the respective variable resistance potentiometer.
These jumpers should not be left open as a lack of a reference voltage on the device will minimize current
sourcing into the respective H Bridge, resulting in very poor motion or no motion at all.

1.4
Motor Outputs
There are three ways of connecting the bipolar stepper motor (for DRV8821) or the dual DC motors (for
DRV8823) into the CPG003_DRV882123EVM-001 evaluation module: four pin header (J4 and J5), four
position terminal block (J2 and J3) and test clips. We do not recommend the connection of a stepper
motor into the test clips as these are Kelvin connections and not rated for high current output.

The Windows Application
The CPG003_DRV8821-23EVM Windows application is the software counterpart for the
CPG003_DRV8821-23EVM-001 EVM. It allows the PC computer to connect to the MSP430F1612
microcontroller though an USB interface chip. Once connection is established and commands are sent,
microcontroller takes care of configuring control signals and administering certain levels of automation,
such as STEP generation (for DRV8821) or SPI communications (for DRV8823).
The graphical user interface (GUI) has been designed to allow for all of the DRV8821/DRV8823 device’s
functionality to be tested without having to intervene with the hardware, except for the proper configuration
of jumpers, when needed.
Figure 21 and Figure 22 show the CPG003_DRV8821-23EVM-001_R1p0.exe main screen. The
application is divided into two tabs: One for the DRV8821 and one for the DRV8823. The menu contains
items to configure and enable/disable the serial port.
The DRV8821 tab contains frames with GPIO control for DRV8821’s control signals, speed, acceleration
and number of steps control for both stepper motors AB and CD, and current control through the
microcontroller’s DACs.
Figure 21. CPG003_DRV8821-23EVM-001_R1p0.exe Main Screen (DRV8821)
The DRV8823 tab contains two frames with the bits that make up the 16-bit serial registers which contain
the control signals to properly articulate each motor. Also GPIO signals such as Reset and SLEEPn are
made accessible through check boxes. Finally, two sliders adjust the reference voltage through the
microcontroller’s DAC outputs.

Updating DAC Output for Current Control (VREF)
If the DRV8821 has been configured to accept VREF analog voltages through the microcontroller DAC
outputs (refer to Jumpers section), then the slider bar on the Current Control frame can be used to set the
VREF voltage.
Figure 24. Current Control Frame
The 12-bit DAC channels, 0/1, are connected to the DRV8821/DRV8823 VREF analog inputs ABVREF
and CDVREF. Changing the DAC digital value from 0 to 4095 changes the analog voltage at the
respective VREF pin from 0 V to 2.5 V respectively, following Equation 1.
2.5 V
VREF = DAC_VALUE · ¾

Where:
1. VREF is the output voltage.
2. DAC_VALUE is a number from 0 to 4095.

3.3.1
Operating the Stepper Motor (DRV8821)
Turning the Stepper Motor
The Windows application, in conjunction with the MSP430F1612 microcontroller, utilizes a series of timers
to coordinate the rate of steps sent to the device. Once all the control signals are configured accordingly,
(ENABLEn = LO, SLEEPn = HI, RESETn = HI; DIR, USM0 and USM1 can be HI or LO depending on
preferred mode of operation; SRn must be L, if external diodes are not populated), the motor is ready to
be turned.
The DRV8821-23EVM-001 customer EVM allows for the possibility of coordinating step rates such that
accelerating and decelerating profiles are achieved. Both acceleration and deceleration are controlled by
the same parameters, acceleration rate and time base.
When the motor starts, it always starts at the slowed PPS speed (62 pulses per second). The controller
will accelerate the motor in order to reach the PPS speed. Acceleration rate is an 8-bit number (0 to 255)
that gets added to the current PPS speed and time base is an 8-bit number (0 to 255) that specifies how
many milliseconds will elapse from one speed increase to the next. Once the specified PPS has been
achieved, the acceleration stops.
The inverse of the above described will command the motor to stop.

Pressing the “Start Steps” button, will start the timer and pulses will be generated at the rate specified by
the decimal number at the PPS text box. Once the “Start Steps” button is pressed it becomes the
“Stepping” button. Press the “Stepping” button to stop the stepper motion.
When the motor is stepping, the “Update Speed” button becomes enabled. Speed can be updated by
modifying the PPS text box and then pressing the “Update Speed” button. The “Speed" button is disabled
every time the motor is not turning because the stepping has been halted by pressing the “Stepping”
button.
3.3.2
Step by Step control
The Step Control frame has a series of tools to control the stepping of the motor on a predetermined
number of steps fashion.
The “Pulse Step” button allows for a single step to be issued. Remember that a STEP takes place when
STEP goes from LO to HI.
