This design is a wing add-on that attaches to the OrangeCrab and adds a Sharp Memory LCD. 400x240 on/off pixels. The board is the size of the monitor.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This breakout connects the Channel 0 TX/RX SerDes from the SYZYGY-TXR connector to the edge of the card to act as a PCIe x1 add-in card.
The collection of papers from previous electronic design competitions includes design ideas, circuit diagrams and corresponding program flow charts for function signal generators, oscilloscopes, automatically controlled balancing cars, radios, etc.
Many modern systems have the majority of their electronics powered by 3.3V or lower, but must drive external loads with ±10V, a range that is still very common in industrial applications. There are digital to analog converters (DACs) available that can drive loads with ±10V swings, but there are reasons to use a 3.3V DAC and amplify the output voltage up to ±10V.
The system developed in this article is based on the existing triggered voice time reporting system, adding a speech recognition circuit, so that the developed system can have the function of dialogue response time reporting, and realize the truly automated and intelligent voice time reporting.
In order to preserve the quality of HDTV and progressive DVD video, a bank of three (RGB/YPbPr), 5-pole reconstruction filters are used to set the 30MHz bandwidth and to provide the >40dB selectivity required by EIA770-3.
A flexible circuit is shown that limits current or removes power in response to a command from the user or other fault-indicating signal. It accommodates manual-reset (MR), over-temperature, and protection in hot-swap applications. Residing on either the backplane/host side or the removable-card/remote-device side of the backplane connectors, it guards against start-up faults when a card or board is inserted into a rack or host with the main power supply turned on.
This application note describes the use of a current-sense amplifier along with an optocoupler to extend the operating voltage range up to 1,000 volts for high-voltage applications. The circuit relies on the optocoupler's isolation barrier to separate the high-side and grounded side of the 1,000V system. Op amps are used to eliminate photodiode non-linearity and drift and provide an accurate output voltage proportional to the load on the 1kV supply.
The MAXREFDES38# subsystem reference design is a 3-channel, high-accuracy, low-power analog front-end solution for EPT/ECT and smart-grid current fault-sensing applications. Hardware, firmware, design files, and lab measurements provide complete system information for rapid prototyping and development.
The Novato reference design (MAXREFDES16#) is a 16-bit, high-accuracy, loop-powered temperature transducer that transmits temperature information from a remote object to the central control unit over a 4–20mA current loop and using the highway addressable remote transducer (HART) communication protocol.
This application note demonstrates how to make a simple system that monitors temperature and analog voltages remotely. On meeting certain alarm conditions, the system can send SMS messages, which are then converted to email and forwarded to the designated email address.
The Alameda (MAXREFDES24#) subsystem reference design features four dense, highly accurate analog outputs in a compact, galvanically isolated form factor. Each channel provides current or voltage. This design uniquely fits in programmable logic controllers (PLC), distributed control systems (DCS ), and other industrial applications. Hardware, firmware design files, and lab measurements are provided for rapid prototyping and development. The board is also available for purchase.
Maxim Integrated's MAXREFDES79# reference design is a fully compliant IO-Link version 1.1, 4-port IO-Link Master using a TEConcept software stack. The system contains four IO-Link master transceivers, a standard ARM® Cortex® M3 processor, and efficient industrial step-down DC-DC converters. The MAXREFDES79# comes preprogrammed and ready to connect with any compliant IO-Link device using a simple-to-use graphical user interface (GUI) program. Design files including schematic, PCB, BOM, GUI software, and compliance report are available for download.
This document explains how the Santa Fe (MAXREFDES5#) subsystem reference design meets the higher resolution, higher voltage, and isolation needs of industrial control and industrial automation applications. Hardware and firmware design files as well as FFTs and histograms from lab measurements are provided.
