Manual – epc600/610 Evaluation Kit – mainboard V1.2
Time-of-flight hardware Evaluation Kit for epc600 and epc610
General Description
Features
The mainboard of the epc600/610 Evaluation Kit is a fully assembled and tested circuit for the evaluation of the epc600 and
epc610 time-of-flight (TOF) products.
The mainboard is divided in two independent sections:
■ Complete development system for applications using
epc600 TOF Range Finders and epc610 TOF Imagers.
■ Dual controller environment with STM32 and PIC10F206 micro controllers.
■ Designed for use with different camera modules with either an
epc600 or an epc610 chip.
■ For epc600: Standalone operation demonstrator with pushbutton
and indicator LED.
■ PC connectivity and power supply by USB.
■ Corresponding user software (PC/Mac) with visualization and
logging features as part of the camera system.
The “Evaluation” main section is equipped with a STM32 ARM Cortex microcontroller. This section provides a powerful and flexible
development environment for the design engineer. It supports all
available camera modules and works with both the epc600 TOF
Range Finder and the epc610 TOF Imager Chip.
The second part of the mainboard, for the “Application with
PIC10F”, is equipped with a PIC10F206 microcontroller. It serves
as a standalone demonstration system and has a simple distance
gauge application implemented. It works with the epc600 Range
Finder product only.
The separate camera modules come either with an epc600 TOF
Range Finder chip or with an epc610 TOF Imager chip. The modules include active LED illumination for the observation area, a
complete lens system and have a cable interface to the mainboard,
allowing a flexible and convenient placement in a lab setup.
Purpose
■ Performance demonstration of epc's 3D TOF technology in terms
of speed, accuracy and operating range.
■ Speed: Integration time, response time.
■ Accuracy: Distance noise, distance drift, absolute distance accu racy.
■ Operating range: Sensitivity, ambient-light suppression.
■ Reference application for evaluation and design engineers.

The Personal computer
■ IBM compatible or Apple (Mac).
■ Man-machine interface for operation and visualization of the evaluation system.
■ Runs the application software.
■ Stores, reads and writes configuration and data files for the application.
■ Host system for ST ARM 32bit Cortex microprocessor software development.
The mainboard
■ Two sections with independent microprocessor systems:
□ The one for the “epc600 / epc610 evaluation system” (Evaluation)
□ The second is a minimal hardware design concept for a Range Finder application with the epc600 (Application with PIC10F).
■ A main switch selects which section will be connected to the camera module.
■ The mainboard/system is connected to the computer by a USB cable for data communication and power supply.
■ The power supply generates all of the necessary supply voltages from the USB connection. An additional external USB power supply
can be added if the PC USB interface is not capable of delivering the necessary power (ca. 1'000mA).
■ The “epc600/epc610 evaluation system” section supports and gives access to the full functionality of the epc600 / epc610 devices.
□ Checks for the correct device identification of the camera.
□ Configures and controls the camera.
□ Reads the picture data from the camera and sends it via USB to the computer.
□ Provides configuration DIP switches and signaling LEDs.
□ A “debug connector” allows advanced users to download their own application. For more information, refer to the manual of the corre sponding processor.
■ The “epc600 standalone demonstration” section with a tiny microprocessor PIC10F206 is a fully functional range-finder concept.
□ This part is not yet supported. There is no functional firmware implemented.
The camera module
■ Is a fully functional module with an epc600 or epc610 chip and optics combined.
■ Connects to the mainboard for power supply, data communication and configuration reading.
■ The configuration setting in the camera can be read back, allowing identification of the type of the chip in the camera.
■ Has a built in epc600 or epc610 chip according the label.
■ Appropriate optics allow for the demonstration of the functionality of the epc600 or epc610 device.
The transmit and receive optics guarantees having a fully functional camera system from the start.
Goals and objectives of this Evaluation Kit:
■ Easy-to-use, plug and play demonstrator to show how epc's TOF products work and which possibilities they offer.
6 / 18
■ Test kit for engineers, enabling first contact with epc's products.
■ Reference design kit for design and development engineers.
■ Supports the user during development and testing of his own hard- and software.
Exceptions of this kit:
■ The kit is a demonstrator. It is not designed for verification of datasheet parameters. Such tests need a dedicated test environment.
■ Not designed for use in final applications.

2.4. Mainboard overview
The mainboard is divided into two areas with independent functionality.
In the „Evaluation“ area (the upper part of the board) is the “epc600/610 evaluation system” It contains the USB interface, the main-micro processor of the evaluation system, some I/O features and the 3.3 -> 5V level-shifting for the communication and I/O lines from the microprocessor to the I/Os of the epc600 and epc610 devices.
The „Application with PIC10F“ area (the bottom part of the board) is not used for the Evaluation Kit currently. It contains a typical rangefinder application with a tiny PIC10F206 microcontroller.
General purpose functions are the power supply on the top of the board, the camera connector and the evaluation/application switch in between the two main areas.
2.5. General purpose functions on the Mainboard
2.5.1. Board supply
Usually, the mainboard is supplied by the host (PC, USB Hub) over the USB cable ( Figure 11, J6/USB FS).

Figure 11: Mainboard: Power supply function
A integrated power management module with a built in power switch is used to manage the supply of the board. As soon as the board is
connected to a USB interface or to an external USB supply, the main-microprocessor is supplied with 3.3V. The switch is initially open and
the 5V or 8.5V supplies are not available until the main-microprocessor had asked the host for high-power devices and has closed the
switch.
If the host is not able to deliver the necessary power, the mainboard indicates an error by blinking LED1. In this case, or if the system is
running without a host, the external USB Power Supply (5V, 1'000mA) needs to be used with the power supply selection switch USB/Ext.
(SW3; see picture below) set to Ext for the external supply through connector J1.
Position
Description
USB (default)
The Evaluation Kit is supplied by the host over the USB FS connector.
Ext.
The Evaluation Kit is supplied by an external USB power supply over the Ext. suppl connector.
Table 4: Power supply selection switch SW3
LED 3.3V and LED 5V/8.5V indicate if the corresponding voltages are available.
All voltages can be accessed over the power supply test points (see Figure 11). The external circuitry may not draw more than 2.5W in total!
13 / 18
Note:
If the following pop-up window appears after “Connect”:
Figure 12: FW boot-up
Reason:
You are using a 1 st series camera module with a V1.2 or V2.0 mainboard. The USB power supply is not compatible
Solution:
Use an external 1'000mA USB supply. Connect it to the appropriate plug on the mainboard and switch to „Ext.“ power supply. After pow er-up press the reset button on the mainboard.
2.5.2. epc600 camera (place P1)
For easier testing and demonstration, the epc600 camera can be fixed on the mainboard with a screw at location P1.
Note:
The camera must be connected via the camera cable to connector J9 of the mainboard (No direct interconnects).
2.5.3. Camera connector J9
Depending of the type of the camera module or with respect to the sensor chip inside a camera, the pins of the J9 camera connector have
different meanings and need different terminations according to Table 5. For camera modules supplied by ESPROS photonics, the pin assignment is already done for the correct operation of the module in combination with the mainboard.

Notes:
Pins 11 and 12 must be terminated, but not necessarily in the camera mod ule. If they are not terminated in the camera, the Evaluation Kit reads back
the chip type by firmware and terminates them according to the signals
MODE and TEST.
For the correct standalone operation of the camera modules (epc600 or
epc610), the signals need to be terminated according to the datasheets.

2.5.4. Selection of the working area (SW2)
With the selection switch SW2, the working area of the mainboard can be selected:
■ In the upper position, the “Evaluation” area is active for the “epc600/epc610 evaluation system”. This mode works for camera modules
epc600 and epc610. The camera is operated and accessed by the Evaluation Kit application software on the user's computer.
■ The lower position of the switch activates the „Application with PIC10F“ option for the “epc600 standalone demonstration”. It is a typical
range-finder application with a tiny PIC10F206 microcontroller. It is not in used for the Evaluation Kit currently.
Caution:
The board must be in the unpowered state when switch SW2 is changed!
Otherwise the board or camera may be damaged.
2.6. “Evaluation” working area
The “Evaluation” area offers the following options for evaluation and test purposes:
2.6.1. USB connector USB FS (J6)
This interface is the communication interface between the host (PC or Mac) and the mainboard. The main task is to transmit all the sensor
information from the Evaluation Kit to the host as well as to transmit the control and status information to the sensor.
Secondly, this interface is used to supply power to the board (refer to chapter 2.5.1: Board supply).
2.6.2. Header J5
Connect or disconnect signals SCLK/SCLK, nss/SDATA, MOSI or MISO. Pins 9 and 10 of J5 are connected to GND (shorted).
The epc600 camera modules communicate over the 2-wire interface (SCLK, SDATA) while the epc610 cameras use SPI communication
(SCKL, nSS, MOSI, MISO). For additional details, refer to the corresponding chip datasheets.
2.6.3. Header J7 (boot option)
Jumper J7-12 (between pin 1 and 2) is used to pull down the STM32 boot0 signal.
Jumper J7-34 (between pin 3 and 4) is used to pull down STM32's port pin PE9.

Table 7: JTAG / SWD connector
To program and debug the STM32, an ARM SWJ-DP interface is implemented. It is a combined JTAG and serial wire debug port that en ables either a serial wire debug or a JTAG probe to be connected to the target. The port is available on the J2 connector (see Figure 10),
which is a standard 10 pin, 1.27mm cortex debug connector (see infocenter.arm.com). For more information about debug support, refer to
the STM32F207 reference manual (see chapter 6.1: Related documents).
2.7.2. STM32 debug (J10)
The STM32 debug connector J10 offers access to six STM32 GPIO port pins that can be set for bug tracing or any other use.

2.7.3. STM32 reset (S2)
The STM32 reset button S2 is connected to the STM32's NRST input pin. A low level (pressed button) causes a system reset of the con troller (for more information refer to STM32F207 reference manual; see chapter 6.1: Related documents). Note that the reset signal is only
connected to the STM32 controller.
2.8. “Application with PIC10F”
This section is not used and in operation for the Evaluation Kit currently.
If the selection switch SW2 is in the lower position, the epc600 chip is working within a typical simple range-finder demonstration applica tion. It is in combination with a tiny PIC microprocessor and an easy-to use 1-button / LED interface.
16 / 18
2.8.1. Microcontroller
The used tiny microcontroller is a 6 pin PIC10F206 from Microchip. It can be programmed by using Microchip's ICD3 In-Circuit Debugger
Interface (see chapter 6.1: Related documents).
2.8.2. 1-button / LED interface (S3 / LED9)
The application's human interface is the 1-button / LED interface (refer to Figure 4). With the Teach (S3) pushbutton, the target distance as
well as commands are entered to the system. The LED Dist (LED9) is signaling if an object is detected (or the actual status of the system).
For a detailed description of the functionality as well the firmware, refer to the “Manual – epc600 Camera”.
2.8.3. 2-wire interface connection J11
If the user connects the 2-wire interface to the epc600 chip by his own external controller, the 2-wire interface can be disconnected by the
jumpers on the header J11.
2.8.4. Signal connector J12
All signals to and from the microcontroller can be accessed by J12 (see Figure 10) for test purposes.
2.8.5. Test point J15 and J16
Test point J15 and J16 are foreseen to connect ground GND to measurement or test equipment (e.g. to an oscilloscope).
3. Camera module
For the descriptions of the camera modules refer to the documents “Manual – epc600 Camera” or “Manual – epc610 Camera”.
4. Setup & installation
For hardware setup and software installation, follow the instructions in the corresponding chapters of the camera manuals.
5. Maintenance and disposal
5.1. Maintenance
The components of the evaluation kit do not need regular maintenance. A functional check is recommended each time the kit is taken into
operation:
■ Check the mounting position and the detection area of the sensor with respect to the operational conditions. Also check that there is no
hazardous situation.
■ From time to time, clean the sensor with a soft towel and with a little soapy water to remove dust or dirt.
5.2. Disposal
Disposal should be done using the most up-to-date recycling technologies for electronic components according to the local regulations and
laws. The design and manufacture of the kit's components are done in compliance with the RoHS legal regulations. Traces of dangerous
materials may be found in the electronic components, but not in harmful quantities.
