SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated OPT3101 Evaluation Module 3 Introduction 2 www.ti.com Introduction OPT3101 device is a high-speed, high-resolution AFE for continuous wave, time-of-flight (ToF) based proximity sensing, and range finding. The purpose of the OPT3101EVM is to expedite evaluation and system development of the OPT3101. The evaluation kit consists of a printed-circuit board (PCB), available for purchase on the OPT3101EVM page, and a software package called Latte, which is available for download on the OPT3101EVM page under software. The PCB is a single-pixel system that uses the OPT3101 device for ToF proximity sensing. The PCB connects to a computer running the Latte software through USB. The Latte software allows visualization and logging of the OPT3101 readings, setting different modes of operation, reading and writing of register settings on the device, and the creation of custom Python® scripts. Figure 1. OPT3101EVM Printed-Circuit Board The following sections are divided into hardware, software installation, using the EVM, and troubleshooting. The last section at the end of this guide includes the EVM schematic, layout, and bill of materials (BOM). The OPT3101EVM Hardware section gives an overview of the OPT3101EVM PCB, covering the different components of the board and outlining the functions of each. The Section 4 section provides the steps needed to install and launch the Latte software package. The Using the EVM section describes how to use the Latte software to take readings on the EVM. 4 OPT3101 Evaluation Module SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated OPT3101EVM Hardware www.ti.com 3 OPT3101EVM Hardware Figure 2 shows the hardware block diagram for the OPT3101EVM. The block diagram includes all major components on the PCB and shows how they are connected. The direction of the arrow shows the flow of information between the components. Figure 3 and Figure 4 show the physical location of these components on the PCB. The following subsections describe each component in detail. Temp Sensor Switch PD I2C_M IN M/P Indicator LED 3x GPIO (R,G,B) GPIO I2C_S GP1 (DATA_RDY) OPT3101 MSP430 GP2 (REF_CLK) LED TX0 3.3 V LDO 5V USB Port Figure 2. EVM Hardware Block Diagram 3.1 MSP430 Microcontroller The MSP430F5503 has a USB interface, allowing connection to a PC, and acts as a communication bridge between the OPT3101 and the PC. The MSP430 microcontroller is loaded with C++ firmware for interfacing with the OPT3101 over I2C, in addition to the other components on the PCB. The MSP430 also has a calibration configuration for the board stored in onboard flash storage. The MSP430 registers 2 USB COM ports with the PC it is plugged in to. The OPT3101 Control Port is used for sending control commands to the MSP430. This includes reading and writing registers on the OPT3101 and interfacing with the MSP430 flash storage. The OPT3101 Data Port is used only for streaming data from the EVM to the PC. This allows for maximum data rates when receiving real-time data from the OPT3101 during high-speed capture. 3.2 I2C Buses and Temperature Sensor The OPT3101 has two I2C buses. On the main I2C bus, labeled I2C_S, the OPT3101 is a slave device. This bus is used to control the OPT3101 and read data by reading and writing registers on the device. The OPT3101 also has a secondary I2C bus, I2C_M, for which it is the master. This bus allows an external temperature sensor and an EEPROM to be controlled by the OPT3101. The OPT3101 contains an internal temperature sensor, which is used for temperature calibration. This sensor has 8-bit integer resolution. Adding an external temperature sensor, such as that used on the EVM, allows up to 12 bits of resolution to be obtained with one sign bit, 7 integer bits, and 4 fractional bits. This allows for more accurate temperature correction. An external EEPROM allows for an OPT3101 register configuration to be stored and loaded on power-up. This means that the device does not need an I2C master to configure it on power-up. On the EVM, only a temperature sensor is used on this bus.

There is a single LED-photodiode pair that connects to the OPT3101 and is used for ToF measurements. The EVM uses a 850-nm centroid (860-nm peak) wavelength IR LED (SFH 4550), and a 900-nm peak sensitivity IR photodiode (SFH 213 FA). Electroless nickel immersion gold (ENIG)cylinders on the EVM encircle both the LED and photodiode. The cylinders provide both optical and electrical shielding between the LED and photodiode, this reduces crosstalk. 3.4 Headers and Power-On Jumper The headers break out a number of signals from the EVM for debug and to provide more flexibility in the ways the EVM can be used. Figure 6 shows how to power the board by placing the power-on jumper on the bottom two pins of J19. This connects the 3.3-V output of the LDO to the rest of the components on the EVM. Figure 5 and Figure 6 show the complete list of signals that are broken out to the headers. J17 1 1 2 2 3 3 SDA_S 4 4 SCL_S 5 5 GP1 6 6 GP2 7 7 VSYNC_RST VD_EXT_3P3 VSS_IN Figure 5.

This works by holding down the switch during power up. This allows firmware to be flashed to the device. CAUTION Flashing new firmware to the EVM erases the calibration stored on the EVM. Never do this unless a firmware update is required, and if this is the case make sure to read the calibration out of the MSP430 flash and create a backup before flashing the new firmware. • • • • The indicator LED is an RGB multi-color LED, which is used by the MSP430 firmware to provide visual feedback. Currently the LED only glows green to signal that the device has firmware and is powered on. However, the firmware supports using different colors to indicate other functions. The micro USB port allows the device to be plugged into a computer using a micro USB cable. The device is powered off the 5-V supply from the USB. TVS diode array connected to all signals routed to the header pins and the USB. This helps with ESD protection. The crystal oscillator provides a 4-MHz clock for the MSP430. 4 Software Installation 4.1 Minimum Requirements Before installing the software, verify that your PC meets the minimum requirements outlined in this section. 4.1.1 4.1.2 Required Setup for OPT3101EVM GUI Software • A PC running Microsoft® Windows® 7 or Windows 10 operating system with at least 325MB of free space • A display with screen resolution of 1200×720 pixels, or greater Additional Requirements for use With Hardware The following additional items are required: • OPT3101EVM • USB to MicroUSB cable (provided in kit) 8 OPT3101 Evaluation Module SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Software Installation www.ti.com 4.2 Installing the Software (PC Application) Download and extract OPT3101EVME3_Latte_v0p8.zip, or a newer released version, from the software section of the OPT3101EVM page on ti.com.

Gui Window Clicking the Start Capture button begins capture. This sends a capture start command over the OPT3101 Control Port to the MSP430 on the EVM. The EVM then begins streaming data over the OPT3101 Data Port. This data is displayed live on the left side of the window. Distance is plotted on the graph. The axis of the plot can be changed by right clicking on the plot itself. Clicking the Stop Capture button, or closing out the window stops streaming data from the EVM. A number of key measurements are provided on this GUI. Distance, phase, amplitude, ambient, and temperature as well as a number of other parameters are all calculated internally on the OPT3101 and transmitted via I2C to the MSP430 and then to the PC over the data COM port. These values are all displayed in the table on the left hand side of the GUI window and summarized in Table 3. Frame Averaging The Sub Frame Count and Avg Frame Count settings shown on the left of the GUI can be adjusted to decrease measurement noise or increase speed of measurement. An increase in avg frames will decrease the standard deviation in measurements while a decrease in avg frames will increase the data collection rate. Please note that these two fields correspond directly to register settings and Sub Frame Count must be greater than or equal to Avg Frame Count. An Avg Frame Count value of 0 corresponds to no averaging. SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated OPT3101 Evaluation Module 13 Using the EVM www.ti.com The frame rate is determined with Equation 1: frame rate (fps) 4000 1 HDRmode SUB _ FRAME _ CNT (1) For example, with HDRmode = True and sub frame count = 32: frame rate (fps) 4000 1 1 25 117.6 frames per second (2) Streaming data at maximum datarate To operate the EVM at the maximum datarate of 3 ksps the following steps need to be taken. First, the mode select must be set to one of the non-autoHDR and non-super-HDR modes. The capture mode select must be set to 2 register mode. Then the Avg Frame Count and Sub Frame Count fields must be set to 1. HDR mode uses an extra frame to determine when to switch LED currents, which limits the EVM to 2 ksps. In 3 register mode, there is too much data to send at higher speeds than 2 ksps. 2 register mode omits the 0Ah register. The OPT3101 device can run at up to 4 ksps, but due to the speed of the MSP430, the maximum speed of the EVM is 3 ksps. Table 2 describes all the fields in the Controls section of the GUI. Table 2. GUI Controls Panel Field Function Capture Mode Select: 3 Register mode Reads all three data registers (08h, 09h, 0Ah) from the EVM. This allows all the data fields to be displayed. Capture Mode Select: 2 Register mode Only reads two data registers (08h, 09h) from the EVM. This should be selected for streaming data at speeds higher than 2 ksps and allows data to be captured at up to 3 ksps. Start Capture Start capture and display of data from the EVM Stop Capture Stop capture and display of data from the EVM Display Sample Count Number of samples (data points) to display on the plot Set Save File Name Clicking the check box allows data to be saved to a csv file. Logging to numpy files will start once Start Capture is clicked with the box checked. After Stop Capture is clicked, the logged data will be combined and saved to the specified csv file. File Sample Count Number of samples captured to be saved to the csv file Mode Select: Super-HDR Places the device in super-HDR mode allowing 4 LED current settings to be automatically selected by the device. See the Super-HDR mode using Sequencer section in OPT3101 ToF based Long Range Proximity and Distance Sensor AFE for more details. Mode Select: AutoHDR-Long Range Places the device in HDR mode allowing 2 of the larger LED current settings to be automatically selected by the device. For longer range measurements or low-reflectivity surfaces. See the Auto HDR Mode section in OPT3101 ToF based Long Range Proximity and Distance Sensor AFE for more details on Auto HDR mode. Mode Select: AutoHDR-Short Range Places the device in HDR mode allowing 2 of the smaller LED current settings to be automatically selected by the device. For shorter range measurements or highly reflective surfaces. See the Auto HDR Mode section in OPT3101 ToF based Long Range Proximity and Distance Sensor AFE for more details on Auto HDR mode. Mode Select: Closeup Selects a very small LED current for extremely-close measurements or very highly reflective surfaces at short range Mode Select: ShortRange Selects a small LED current for shorter-range measurements or highly reflective surfaces Mode Select: MediumRange Selects a medium LED current for medium-range measurements Mode Select: LongRange Selects a large LED current for large-range measurements or low-reflectivity surfaces Sub Frame Count Raw value of the SUB_FRAME_CNT register. This is the total number of sub-frames in a frame. The number of sub frames in a frame = SUB_FRAME_CNT + 1. This number must be equal or greater than NUM_AVG_IQ. Ave Frame Count Raw value of the NUM_AVG_IQ register. This specifies the number of sub-frames to be averaged in a frame. Averaging sub-frames = NUM_AVG_IQ + 1. 14 OPT3101 Evaluation Module SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Using the EVM www.ti.com Table 3 describes the data that is displayed by the GUI when the software is capturing data from the EVM. Table 3. GUI Data Capture Fields Field Corresponding register and description Distance The calculated distanced derived from the phase and the calibration information in millimeters Phase The raw data from the PHASE_OUT register. The OPT3101 uses the phase shift between the LED signal emitted and photodiode signal received to determine distance. See the Introduction to Time-of-Flight Optical Proximity Sensor System Design Guide, for more details on time-of-flight operation. Amplitude The raw data from the AMP_OUT register. A 15-bit digital representation of the full-scale signal amplitude. This is the signal strength of the returning signal to the AFE. This number is related to the signal-to-noise ratio. The lower the amplitude, the noisier the signal will be. As the amplitude goes down, the standard deviation for distance and phase measurements will generally increase. As distance between the EVM and a target is increased or reflectivity of a target is decreased, the amplitude will decrease. space ● spThe HDR, and super-HDR functionality of the OPT3101 allows two or four LED current values to be used which allows an space * spincreased range while maintaining relatively high amplitude. Ambient The raw data from the AMB_DATA register. This is a measurement of the environmental IR light that is landing on the sensor. This measurement is used to reduce the effect of the ambient light on the signal and computed distance through the ambient rejection and ambient calibration functionality of the device. tMain The derived data from the TMAIN register. The temperature reading in degrees Celsius from the internal sensor on the OPT3101. The tMain and tillum measurements are used in calibration to compensate for phase and crosstalk drift across temperature. tillum The derived data from the TILLUM register. The temperature reading in degrees Celsius from the external temperature sensor soldered to the EVM PCB. illumCh The raw data from the TX_CHANNEL register. On Super-HDR mode this field indicates whether the 2 larger (illumCh=1) or 2 smaller (illumCh=0) current values are being used. illumDAC The raw data from the HDR_MODE register. In HDR mode this field indicates whether the larger (illumDAC=1) or smaller (illumDAC=0) current is being used. In Super-HDR mode this field indicates which of the 2 current values indicated by the illumCh field are being used. SignalSat The raw data from the SIG_OVL_FLAG register. A value of 1 indicates that the amplitude reading has saturated. AmbientSat The raw data from the AMB_OVL_FLAG register. A value of 1 indicates that the ambient reading has saturated. SampleCounter The derived data from the FRAME_COUNT0, FRAME_COUNT1, and FRAME_COUNT2 registers. Indicates the current data frame that is being received from the OPT3101. This value starts at 0 and increments with each frame the OPT3101 reads. After reaching 31 this value loops back to 0. Plots The GUI contains a distance plot Figure 15 and a composite plot Figure 16. These plots can be switched between, using the tab buttons above the plot. The distance plot is a graph of the distance reading in millimeters on the y-axis against the sample count on the x-axis. The composite plot overlays both distance data and amplitude data. The plot settings can be tweaked by right clicking on the plot. The xaxis and y-axis options under the right-click menu allow the range of x- and y-axes displayed to be changed. There is also an auto option that will dynamically change the range to match the data. Scrolling will zoom in to or zoom out from the plot. Left-clicking and dragging will display a yellow rectangle that will, upon releasing the mouse, zoom the data to the rectangle drawn. Right-clicking and dragging up or down zooms the y-axis. Right-clicking and dragging right or left will zoom the x-axis. Right clicking and selecting "View All" will reset the view.

These scripts allow for initialization of the device including loading calibration data from the EVM flash memory, launching a live view window with measurement plot and readings, and additional functionality such as reading from the flash and selecting a specific LED current for the device to use. For advance users or users looking for more flexibility when using the OPT3101EVM these python scripts are available in an integrated development environment (IDE) window that is minimized when TI-Latte is launched. The IDE window allows advanced users to customize the existing scripts or write new scripts SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback OPT3101 Evaluation Module Copyright © 2018, Texas Instruments Incorporated 31 Appendix www.ti.com Figure 23. IDE Window Figure 23 shows the scripts window. Customization of the 01-variableSetup.py scripts allows for initialization paremeters of the device to be changed. Latte also provides functionality to write custom Python scripts for testing and evaluation purposes with the OPT3101. The example scripts provided can be used as a reference to write custom scripts. The default script install location is: C:\Users\ \Documents\Texas Instruments\Latte\projects\opt3101 32 OPT3101 Evaluation Module SBAU309A – February 2018 – Revised June 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Appendix www.ti.com 8.1.2 Initialization The EVM is initialized by running the devInit.py script in Latte. This runs the variablesSetup.py, Initialization.py, and loadRegistersFromFlash.py scripts in addition to creating the objects for interfacing with the device (dev), the device registers (regProg), and the capture infrastructure of the MSP430 on the EVM (capDev), which allows for higher speed data transfer over a dedicated data COM port. Running the devInit.py script will automatically run the launchGUI.py script after completing initialization steps. This will display the graphical window for controlling the EVM and visualizing data. 8.1.3 Calibration The OPT3101 device has a number of calibration features to increase the device’s performance that are loaded when running devInit.py. The EVM is calibrated for internal crosstalk, illumination crosstalk, phase offset, crosstalk over temperature, phase offset over temperature, and ambient correction. For more details on these calibration features see OPT3101 ToF based Long Range Proximity and Distance Sensor AFE and the OPT3101 Distance Sensor System Calibration. The EVM calibration values are stored onboard the flash of the MSP430. The calibration values are loaded from the flash into the OPT3101 using the loadRegistersFromFlash.py script in Latte. 8.1.4 Running the Scripts After launching Latte, expand the OPT3101 directory on the left hand side of the window under Files by clicking the triangle to the left of the directory name. This displays the calibData, drivers, and OPT3101EVMrevE3_Demo folders. Further expanding the OPT3101EVMrevE3_Demo folder will display all the example scripts as shown in Figure 24.

This displays the contents of the script on the center of the window. With devInit.py still selected in TI-Latte, click Run>Buffer from the top menu bar of TI-Latte (or press F5) to run the script. Once completed, the live view GUI is opened in a new window. More details on the live view GUI are given in the following section. Additional info is also displayed in the log window in the lower left- hand corner of the main window. Figure 25 shows the register view and log output added to the main window. Figure 25.
