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.

  • Page 17: Mainboard Overview

    The mainboard is divided into two areas with independent functionality. In the „Evaluation“ area (the upper part of the board) is the “epc901 evaluation system” It contains the USB interface, the main-micropro - cessor of the evaluation system. There are also communication and I/O lines on the 3.3V level to the epc901device. There are other parts which are not used for this application.

  • Page 24: Software "Epc901 Evaluation System" And User Interface

    4.1. Overview This chapter describes the epc901 Evaluation Kit software (SW) and graphical user interface (GUI). The user interface is designed as a di - alog based application. The software operates the epc901 camera module, reads the data delivered by the module and allows for data log- ging.
  • Page 25: Basic Operation

    The Evaluation Kit requires firmware that runs on the ARM controller. This firmware configures the chip, performs the measurements, cal - culates the result values, interfaces to the computer software and much more. As the development around the epc901 device is ongoing, there will be regular updates of this software.
  • Page 26: Log Dialog

    The firmware is on the CD enclosed in the camera package. 4.1.5. Log dialog This function allows data logging for offline analysis of epc901 chip read-out data. The data stream can be collected either by number of measurement counts or by a logging time.
