Manual – epc600 Camera Spot
Time-of-flight epc600 camera, 1 pixel, spot angle view
General Description
The epc600 Camera Spot is a fully assembled and tested T F
Range Finder camera to be used with the epc600/610 Evaluation
Kit.
The module includes an epc600 T F Range Finder chip, an active
IR LED illumination for the observation area, a complete lens sys-
tem and a cable interface to the mainboard. This allows for a flexi-
ble and convenient placement in a lab setup. The module has a
1.4° x 1.4° optical aperture angle.
In combination with the epc600/610 Evaluation Kit (which provides
all hardware to operate the epc600 Range Finder module), the
user has a fully functional T F evaluation system.
The included application software enables the user to explore the
T F Range Finder technology as well the epc600 Range Finder
chip.
Features
■Fully functional T F Range Finder camera with a 1 pixel epc600
imager chip.
■Comprehensive application software with a graphical user inter-
face to operate the epc600 chip in the camera module.
■Automatic mode to measure distances with adaptive integration
times.
■Manual mode to run the camera in an individual set-up or to ana -
lyze the raw data.
■Possibility to store and reload operating configurations.
■Functionality for logging measurement data on a PC.
Purpose
■Performance analysis of the epc600 chip in terms of speed, oper -
ating range and accuracy.
■Demonstration and evaluation of the hard- and software.
■Development environment for user specific epc600 chip applica -
tions.

Figure 6: Block diagram (* not implemented)
The Personal computer
■IBM compatible or Apple (Mac).
■Man-machine interface for the 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. 200mA).
■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 epc600 camera module
■Is a fully functional module with the epc600 T F Range Finder chip and optics combined.
■Connects to the mainboard for power supply, data communication and configuration reading.
Goals and objectives of this Evaluation Kit:
■Easy-to-use, plug and play demonstrator to show how epc's T F products work and which possibilities they offer.
■Test kit for engineers, allowing for a 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. Hardware of the camera
The electronics of the camera module contains the epc600 chip, the buffering of the supply voltage, the crystal for the chip clock, two IR
emitter LEDs and a connector for the cable to the mainboard. The housing incorporates the emitter and receiver lenses. It minimizes opti -
cal crosstalk.
2.4.1. Camera connector J1
Pins 9, 10, 11 and 12 must be terminated, but not necessarily in the camera module. If they are not terminated, the Evaluation Kit reads
back the chip type in software and terminates them according to the signals M DE and TEST.
For camera modules supplied by ESPR S photonics, the pin assignment is already done for the correct operation of the module in combi-
nation with the mainboard.
For the correct standalone operation of the epc600 camera module, the signals need to be terminated according to the Table 5 and the
datasheet epc600.
