LXI Standards Documents are developed within the LXI Consortium and LXI Technical Working
Groups sponsored by the LXI Consortium Board of Directors. The LXI Consortium develops its
standards through a consensus development process modeled after the American National Standards
Institute, which brings together volunteers representing varied viewpoints and interests to achieve
the final product. Volunteers are not necessarily members of the Consortium and serve without
compensation. While the LXI Consortium administers the process and establishes rules to promote
fairness in the consensus development process, the LXI Consortium does not exhaustively evaluate,
test, or verify the accuracy of any of the information contained in its standards.
The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.

DESCRIPTION:
This example should be used together with ex2a-tx433.asm. One nRF9E5
evaluation board (receiver) should be programmed with the hex-file generated
from assembling this file and the other evaluation board (transmitter)
programmed with the hex-file generated from assembling ex2a-tx433.asm.
All switches on the DIP-swith S206 on the receiver must be set to the "on"
position and all switches on the DIP-swith S205 on the transmitter must be
set to the "on" position.
When one of the switched SW1-SW4 on the transmitter is pressed the
corresponding LED on the receiver is turned on.
The functionality is the same as in ex2c-rx.c.
This is an example USB project showing how to interface an optical mouse sensor (the ADNS-2620) with a standard XP/Vista computer.
The TD-USB-01 board with a PIC18F2550 communicates with:
* the PC: USB 2.0 through a mini-B connector.
* the mouse sensor board: SPI over 4-wire flatcable.
Sensing and planning are at the core of robot motion. Traditionally,
mobile robots have been used for performing various tasks
with a general-purpose processor on-board. This book grew out of
our research enquiry into alternate architectures for sensor-based
robot motion. It describes our research starting early 2002 with the
objectives of obtaining a time, space and energy-efficient solution
for processing sensor data for various robotic tasks.
New algorithms and architectures have been developed for
exploration and other aspects of robot motion. The research has
also resulted in design and fabrication of an FPGA-based mobile
robot equipped with ultrasonic sensors. Numerous experiments
with the FPGA-based mobile robot have also been performed and
they confirm the efficacy of the alternate architecture.
