Manual – epc901 Evaluation Kit
General Description
The Evaluation Kit epc901 is a fully assembled and tested system
for the evaluation of the the epc901 line imager. The Evaluation Kit
consists of an epc901 camera module, a mainboard, cables and
software.
The “Evaluation main section is equipped with a STM32 ARM Cor-
tex micro controller. This section provides a powerful and flexible
development environment for the design engineer. It supports all
the epc901 line imager camera module.
The camera module comes equipped with an epc901 line imager
chip. The module includes a complete lens system and a camera
cable connects it to the mainboard, allowing a flexible and conve-
nient placement in a lab setup.
Features
■Fully functional line imager camera 1'024x1 pixel with epc901
line imager chip.
■Application software with graphical user interface to operate the
epc901 chip of the camera.
■Possibility to store and reload operating configurations.
■Functionality for logging measurement data on PC.
■Complete development system for epc901 line imagers.
■PC connectivity and power supply by USB.
■Corresponding user software (PC/Mac) with visualization and
logging features as part of the camera system.
Purpose
■Demonstration system for epc's line imager technology chips.
■Reference application for evaluation and design engineers.

Personal computer
■Windows PC compatible or Apple (Mac).
■User interface (GUI) 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.
Mainboard
■Two sections with independent microprocessor systems:
□ Main section “Evaluation System .
□ Section „epc600 standalone demonstration – NOT USED
■A main switch selects which section will be connected to the camera module. Always leave this on „Evaluation“.
■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 “evaluation system section supports and gives access to the full functionality epc901 device.
□Connects video output and 2-wire bus.
□Reads the picture data from the camera and sends it via USB to the computer.
□A “debug connector allows advanced users to download their own application. For more information, refer to the manual of the corre-
sponding processor.
Camera module
■Is a fully functional module with an epc901 chip and optics.
■Connects to the mainboard for power supply, data communication and configuration reading.
■Provides solder pads to set chip configuration according to the datasheet.
■Appropriate optics allow for the demonstration of the functionality epc901 device.
Goals and objectives of this Evaluation Kit
■Easy-to-use, plug and play demonstrator to show how epc's TOF products and line imager work and which possibilities they offer.
■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.
Not in scope
■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.

2.2. epc901 chip
Refer to the Datasheet epc901 for any details concerning the epc901 chip and its operation.
2.3. epc901 camera module (epc901 evaluation hardware)
As a epc901 camera, epc offers a chip carrier board and an evaluation board for an easy test setup. It simplifies the use of epc's
1024x1pixel CCD line sensor. The Chip Carrier Board holds the chip and offers an easy lens mount possibility.
The Evaluation Board carries the Chip Carrier Board and defines the operating configuration of the epc901 by respective pin configuration.
It offers also the connection to the customer application.
M12 and C-Mount lens holders and a small assortment of lenses are available separately.
In the minimal setup, only a 3V supply as well as the READ, SHUTTER and CLR_PIX signals are necessary, to use this kit in the default
configuration.
The default configuration of the Evaluation Board V2 is as follows (as per datasheet epc901) :
■Mode: single mode
■Bandwidth: 1MHz
■I2C Address: 0101b
■Region of interest (ROI_SEL): 0 .. 1023
■Gain: 1
■Read direction (RD_DIR): 1023 … 0
■Horizontal binning (HOR_BIN): 1 pixel
For alternative configurations – i.e. for low readout noise operation refer to the epc901 datasheet.
Figure 7 show the combination of the evaluation hardware with the chip carrier board inserted into the edge connector socket of the
evaluation board . Figure 8 and Figure 9 depict the hardware with optional lens mount and lens, respectively.
