It allows the PC computer to connect to the MSP430F1612 microcontroller through an USB interface chip. Once the connection is established, and commands are sent, microcontroller takes care of configuring control signals and administering certain levels of automation, such as micro stepping generation for (DRV8812/13), STEP and DIR control (for DRV8824/25) or PWM output (for DRV8812/13/14/40/41/42/43). The graphical user interface (GUI) has been designed to allow for all of the DRV88xx device’s functionality to be tested without having to intervene with the hardware, except for the proper configuration of jumpers, when needed. The application has five tabs: one for each one of the five available device flavors. The GUI has five pages SLVU361C – April 2010 – Revised October 2018 Submit Documentation Feedback Copyright © 2010–2018, Texas Instruments Incorporated DRV88xx Evaluation Modules 15 DRV88xx EVM GUI Overview • • • • • www.ti.com DRV8802-12-13-14 DRV882-25 DRV8840 DRV8841-43 DRV8842 Each page has GPIO control for the control signals, stepper motor control for start/stop and speed, and current/decay control through the MSP430 DACs. Figure 22. DRV8802-12-13-14 Tab The DRV8802-12-13-14 tab contains all the control signals needed to control motor enablement (ENABLE A, ENABLE B), the direction of rotation (PHASE A, PHASE B) and current control (AIx and BIx). Access to both DAC generating VREF analog voltages is achieved by moving sliders. Another set of sliders allows the control of PWM duty cycle on ENABLE x pins. This is intended for motion control. A simple stepper demo allows hooking a bipolar stepper to the DRV8812 EVM and has its speed and direction controlled by an algorithm which modulates the VREF current in a high-resolutionmicro stepping style. This function is achieved by using both MSP430 DAC outputs and is only available if several jumpers are set for dual DAC connection (as default). 16 DRV88xx Evaluation Modules SLVU361C – April 2010 – Revised October 2018 Submit Documentation Feedback Copyright © 2010–2018, Texas Instruments Incorporated DRV88xx EVM GUI Overview www.ti.com Figure 23. DRV8824-25 Tab The DRV8824-25 has an updated GUI that contains all the necessary control signals for driving a bipolar stepper. Important aspects to control are enablement, direction of rotation, speed, number of steps, reference voltage (for maximum current) and degrees of microstepping.

DRV88xx About Page 3.2 DRV88xx GPIO Control Signals Once the application is communicating with the interface board, the control signals can be actuated by checking or un-checking check boxes on the Signals frame. Each tab will have a different set of control signals as depending on the device being interface on. nSLEEP and nRESET control signals will be on all tabs. Functionality of control signals is identical across the platform. A checked checkbox translates to a HI level on the respective control signal. Unchecked checkboxes translates to a LO level on the respective control signals. Figure 30.

The GPIO operates as HI and LO according to the checkbox. To have the DECAY pin floating, engaging mixed decay mode, simply remove the decay jumper JP3. 3.3 Updating DAC Output for Current Control (VREFA and VREFB) If the DRV88xx 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 31. Current Control The 12-bit DAC channels 0/1 are connected to the DRV88xx 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 the equation: 2.5 V VREF = DAC_VALUE · ¾ 4095 (1) Where: VREF is the output voltage. DAC_VALUE is a number from 0 to 4095. Moving the sliders will update the “VREF = xV” caption below each respective slider with the result of the previous equation giving the user an idea of what analog voltage is being presented at the reference voltage input. 3.4 DC Motor Speed Control (PWM) The DRV8802-14 can be utilized to control DC motors. For the purpose to control DC motor speed, a slider is provided which applies a PWM to the ENABLE line. The PWM slider consists of an 8-bit number so position from 0 to 255 are obtained. The MSP430 directly transforms this 8 bit number into the respective duty cycle. PWM frequency is around 31.25 kHz. 22 DRV88xx Evaluation Modules SLVU361C – April 2010 – Revised October 2018 Submit Documentation Feedback Copyright © 2010–2018, Texas Instruments Incorporated DRV88xx EVM GUI Overview www.ti.com Figure 32.

Resulting duty cycle is an integer number between 0 and 100 and it is computed according to the equation: PWM ¾ %Duty Cycle = 255 · 100 (2) The DRV8841-43 will offer the same ability to apply a PWM signal to each one of the INx pins. Figure 33. PWM Signal on INx Pins 3.5 3.5.1 Operating the Stepper Motor (DRV8824) 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, USMx can be HI or LO depending on preferred mode of operation), the motor is ready to be turned. The DRV88xx 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 speed has been achieved, the acceleration stops. When the motor stops, the inverse of the above description occurs. 24 DRV88xx Evaluation Modules SLVU361C – April 2010 – Revised October 2018 Submit Documentation Feedback Copyright © 2010–2018, Texas Instruments Incorporated DRV88xx EVM GUI Overview www.ti.com Pulses Per Second Accel Rate Time Base Figure 34. Turning the Stepper Motor The Windows application frame to control speed, acceleration and deceleration, as well as motor start and stop, is shown in Figure 35. Figure 35. Speed Control 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. 3.5.2 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. SLVU361C – April 2010 – Revised October 2018 Submit Documentation Feedback Copyright © 2010–2018, Texas Instruments Incorporated DRV88xx Evaluation Modules 25 DRV88xx EVM GUI Overview www.ti.com Figure 36. Step Control To move the motor a number of steps and then stop, fill the # of Steps text box with a decimal number from 0 to 65535 and the motor will move that number of steps at the speed specified on the PPS text box. No acceleration or deceleration takes place under this function. 3.5.3 Stepper Speed Calculator In order to easily translate steps per second to actual angular velocity, a simple calculator is provided. The calculator extracts step resolution information from the Mode x pins values and STEP frequency from the PPS text box. The user must then provide number of steps per resolution the motor has been manufactured to achieve. For example, a 1.8 degrees stepper motor would have 200 steps per revolution, and so on. By pressing the Compute button, the calculator reports the revolutions per second and revolutions per minute parameters. For example, on the picture below, the stepping rate was set to 4000 steps per second. While microstepping with 4 degrees of microstepping, a motor with 200 steps per revolution should be moving at 5 revolutions per second or 300 revolutions per minute. Figure 37.
