This device has been optimized to drive a single bipolar stepper with up to 16 degrees of internally generated microstepping. The EVM houses an MSP430 microcontroller and a USB interface chip. The USB chip allows for serial communications from a PC computer where a Microsoft® Windows® application is used to schedule serial commands. These commands can be used to control each signal of the device, and drive the stepper motor by issuing the step commands at the desired rate. The microcontroller firmware operates using internal index mode. This user's guide details the operation of the EVM, as well as the hardware configurability of the EVM.

Install the drivers and GUI. Refer to Appendix A for instructions. Connect the wires of the stepper motor to terminals AOUT1, AOUT2, BOUT1, and BOUT2. Connect the VM power supply, but do not apply power at this step. Connect the USB cable between the PC and the EVM. After the USB is connected to the EVM, the Status LED will begin to blink. 5. Open the GUI. The GUI can be found in the start menu at Texas Instruments → DRV8884EVM → DRV8884EVM vX.Y , where X and Y are the revision numbers. If a shortcut was created, the shortcut can also be double clicked to open the GUI. It may take up to 30 seconds to establish the connection. If the connection is not established, select the COM port under the Options menu. The BaudRate is 9600. 6. Apply desired voltage (8 to 37 V) to the VM and GND connections. 7. Configure the current settings, step mode, decay mode, and torque as desired as: Figure 3. GUI at startup (a) The current is calculated using the VREF slider, the Sense resistor value, the Torque setting, and the Step mode setting using Equation 1. § 1.232 VRREF _ R · I FS 1 A ¨ ¸ u TORQUE u StepModifier 1.232 © ¹ where StepModifier is 0.71 for full step and 1.0 for other STEP MODE settings (1) (b) The number 1.232 is based on the maximum current allowed using the configuration. If VRREF = 0 V, the maximum current is 1.0 A. The 12-bit DAC channel 1 is connected to the DRV8884 analog input RREF through a 30-kΩ series resistor. The DAC voltage begins at 1.232 V (0%) and ends at 0V (100%).

Wake and Enable the device for operation. (a) After setting up the control signals for the DRV8884, enabling the DRV8884 requires selecting both the WAKE and ENABLE toggle buttons. When toggled, WAKE or ENABLE switches between red to green. (b) The WAKE toggle button, which controls the nSLEEP pin, is used to wake the DRV8884. The ENABLE toggle button, which controls the ENABLE pin, is used to enable the DRV8884 outputs. (c) A message which states that “*Both WAKE and ENABLE must be Green to enable the motor control buttons” is visible until both the WAKE and ENABLE toggle buttons are activated. After these two toggle buttons have been activated, the message disappears and the Start/Stop and Move Steps toggle buttons become available. (d) If the WAKE or ENABLE toggle buttons are selected during motor operation, the motor is immediately stopped and the STEP control signal from the microcontroller is reset. Figure 4. Wake and Enable Toggle Buttons 6 DRV8884 Evaluation Module (EVM) User's Guide Copyright © 2016, Texas Instruments Incorporated SLVUAQ3 – April 2016 Submit Documentation Feedback Operation of the EVM www.ti.com 9. The DRV8884 EVM is now awake and can be commanded to turn the motor. This is done by either selecting Start/Stop Steps, Move # of Steps, or Reciprocate. • The Start/Stop Steps toggle button is used to run the motor indefinitely. The motor will accelerate to the target speed and run until the Start/Stop Steps toggle button is selected. When the Start/Stop Steps toggle button is selected, the red button will change to green, and the Move Steps and Reciprocate toggle buttons will be disabled. • The Move Steps toggle button is used to allow movement of an exact number of steps. When the Move Steps toggle button is selected, Move Steps will turn green, and the Start/Stop Steps and Reciprocate toggle buttons are disabled until the number of steps have completed. • The Reciprocate toggle button is a special case of the Move Steps. When selected, the motor will advance the specified number of steps in the direction initially set by the control inputs. After a short pause, the motor will then advance the same number of steps in the opposite direction. This sequence is repeated until the Reciprocate toggle button is selected. • When the Reciprocate toggle button is selected, Reciprocate will turn green, and the Start/Stop Steps and Move # of Steps buttons are disabled until the Reciprocate toggle button is set to red, and the number of steps have completed. Figure 5. Reciprocate Toggle Button As an extra precaution, the motor can be stopped by selecting either the WAKE or ENABLE toggle buttons. When either is selected, the STEP commands are stopped, and the motor control buttons are disabled. To re-enable motor control, set the WAKE and ENABLE toggle buttons to green.

This area allows for determining the best current settings during running at various speeds and when holding torque is applied. *Both WAKE and ENABLE must be Green to enable the motor control buttons. Figure 6. Motor Motion Profile Motor motion only happens by using an acceleration profile which is detailed later in this section. A detailed explanation of each stepper control is provided in the following sections. This frame allows the configuration and running of the stepper with the direction as specified by the DIR checkbox, with the current decay mode as specified under the Decay Mode checkbox and the microstepping resolution as specified under the Step Mode drop-down box. 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 GUI will send the information to the microcontroller as PPS, and the microcontroller will transform it into the respective clock cycles needed for the timer to generate accurate STEP pulse timing. 8 DRV8884 Evaluation Module (EVM) User's Guide Copyright © 2016, Texas Instruments Incorporated SLVUAQ3 – April 2016 Submit Documentation Feedback www.ti.com 7.1 Motion Control Frame (Includes Start/Stop Steps and Move Steps) Start/Stop Steps The acceleration profile is coded inside the microcontroller to accept both the starting speed PPS and target speed PPS as a clock cycle number. When the start steps command is issued (Starts/Steps button is selected), the PWM timer generates steps at a rate specified by the start speed PPS parameter. When accelerating or decelerating, PPS is adjusted every 32 ms based on the integer value of PPSPS / 32 ms. If a non-zero value of PPSPS is entered, a minimum value of 1 is used. The step rate is increased by the calculated value until the target speed is reached. NOTE: If the starting speed is greater than or equal to the target speed, the acceleration rate is set to 0. This will prevent further speed changes until the motor is stopped, and new starting and target speeds are entered. TI recommends setting the starting speed to one-half the target speed to avoid this scenario. The very same start steps 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. When the target speed PPS is reached, the acceleration profile ends and the motor continues running until the stop stepper command is issued (Start/Stop Steps button is selected again). When the stepper is commanded to stop, the controller does exactly as it did while accelerating, but in reverse to decelerate until the stop speed PPS is reached, in which case the motor fully stops. A second motor actuation is provided by the Move # of Steps and Reciprocate commands in which a programmed number of steps are issued and then the motor stopped. The acceleration and deceleration profiles work similarly as before, except when the deceleration starts and when the motor actually stops are a function of the Steps to Stop and deceleration rate parameters. Figure 7 shows the acceleration profile and the role each parameter plays during speed computation. *Both WAKE and ENABLE must be Green to enable the motor control buttons. Figure 7. Acceleration Profile SLVUAQ3 – April 2016 Submit Documentation Feedback DRV8884 Evaluation Module (EVM) User's Guide Copyright © 2016, Texas Instruments Incorporated 9 Motion Control Frame (Includes Start/Stop Steps and Move Steps) 7.2 www.ti.com Move Steps When moving the stepper a certain number of steps, use the move steps function. Parameters from the other frames are reused as explained previously. Two new parameters are added to properly control the limited number of steps actuation. Number of Steps— Number of 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 and 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 met before all the number of steps is issued, then the motor rotates at the stop speed value until all the steps are executed. Ideally, the system should be tuned to resemble the case in which the controller executes all the commanded steps at a speed as close as possible to the stop speed. In the event this is not possible, due to the particular parameters being chosen, stopping the motor at a speed very close to the stop speed is often sufficient to ensure good motion quality and application performance. Figure 8 shows the three conditions possible when stopping and what action results. 1. Motor reaches stop speed at the stop speed. 2. Motor reaches stop speed before the stop speed is reached. 3. Motor runs out of steps before reaching stop speed. Figure 8. Stop Conditions 8 EVM Documentation The EVM schematics, layout, and bill of materials (BOM) are provided in the hardware file (SLVC657).

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
