I need a simple Verilog LPDDR2 memory Controller for the Cyclone V GX Starter kit. This FPGA evaluation board has an on-board Micron MT42L128M32D1LF-25 WT:A LPDDR2 memory chip. I need to access this chip from Verilog using a simple SRAM-like interface. This memory controller should be your own design, or a modified open-source one whose license allows for modification and distribution. The user side interface should be simple and allow for reads and writes as seen below. (for writing) 1. Place an address on the bus. 2. Place the data on the bus. 3. Set read/write direction to write. 3.5 Initiate the write. 4. Wait for confirmation that write completed (for reading) 1. Place an address on the bus. 2. Set read/write direction to read.\ 2.5 Initiate the read. 3. Wait for signal saying data on bus is now valid. Status signals about the current state of the memory controller should also be available. The deliverable should be a Quartus project (.qpf), a settings file (.qsf) contai...

General description: We need a device that will record data using a magnetic head from a magstripe to an internal flash memory in PCM or similar format, and a PC software that will run on Windows to download the data from the device and decode the audio data to ASCII. The device: The source code for the device MCU should be written in C/C++ for better portability, preferring the MCU vendor development system. We prefer using the 8-bit PIC family from Microchip as MCU, but AVRs are also acceptable. The device should be built on a PCB with the following size: Length - 10-15mm Width - 5-7mm Thickness - max. 2 or 2,5mm - with components included Power consumption must be very low -- about 7-8mA in standby and max. 12mA in recording mode. The ideal connection between the device and the computer should be direct USB with solderable pads for the connector. Serial interface communication with a MAX232 or equivalent circuit on an aditional board is also acceptable. The capacity of the f...

Currently I have a User Interface PCB design that works in our products (Homogenizer). However, we are wanting to make updates and add more functionality. This will be a relatively simple project. We own all of the board files and schematics. These files will need to be used to further optimize the design for manufacturing as well as incorporate a few minor changes. The individual needs to be skilled at PCB design and Electrical Development. Please feel free to contact with any further questions and details if interested. We will be able to provide the project scope.

If you are a hardware engineer, this is the task for you. Use your creative skill to come up with a way to program or manage any vacuum pump to have some intelligence. The vacuum pump can be programmed to pulse, meaning you can program it to increase slowly, wait for a short period, then decrease slowly, wait for a short period and then increase slowly until it reaches the highest vacuum level. Step 1: Convert any aquarium(fish tank) pump, whisper pump or refrigerator pump into a "vacuum pump". You can search for any of these on ebay or amazon. It costs anywhere between $10 to $20 USD. If needed, I can provide instructions on how to modify these pumps into a "vacuum pump". It is best to create an "add-on" device that can work with any existing vacuum pump. This way, we don't need to spend huge amount of money to manufacture the vacuum pumps from scratch. Step 2: Use whatever suitable programming language to create the below User Interface to acce...

The program is written in Python, and uses some Python built-in mathematical operations. I want it to be converted to C++. The program does not require any user interface, it is used to perform some computations for aircraft model. The tricky parts are python built in operations and input-out put files. I hope it can be finished within 2 weeks.

Moving Guard Overview: Small Plastic "Tags" are applied to things being transported, for example a piece of furniture being moved across country. These tag record and supply feedback data consisting mainly of 3 hazard occurrences while in transit. 1. extreme impact, 2. tilt, 3. liquid/temperature hazard that may occur during transit of the item it is attached to. Once any of these events occur, the event specifics, time and location data is sent to accompanying software. More data can be downloaded (via Bluetooth or micro USB link) such as the entire transit log of impact tilt and moister showing any small variations, once the tags are back with the user to simplify any transmission costs. This product is for the average consumer so it must be a fairly low cost item for them to purchase Hardware: Very durable small plastic "Tags" (no larger than the palm of a hand) that can temporarily adhere securely to anything (may have different adhesive attachments for adher...

System Specification for Video Frame Buffer Version:1.0 24 January 2015 The unit is to be designed to capture video (video meaning image) input from a personal computer, buffer the captured video images in internal SDRAM and replay the captured video images to up to 48 individual VGA monitors in turn. The unit will be designed to meet the following requirements: - 1. The unit is to be designed such that the user can input up to a maximum of 48 images of a resolution of 800x600 (standard) up to a maximum of 1920x1080 (configurable). Each individual image to be captured is to be transmitted to the unit via a standard 19 pin HDMI or a VGA interface. The user presses a capture button on the unit when the user wishes the unit to capture a given image, the unit then captures the image and stores it in a SDRAM buffer. Each captured image is then displayed on one of up to 48 VGA monitors (in turn). The monitors will support VGA input at 800x600 75 frames per second. 2. Rather than one P...

Revision 3.1 / January 22, 2015 We are seeking sources to design and/or to produce a custom micro-controller (MC) based Printed Circuit Board (PCB) with very low profile and ultra low power consumption that will be embedded into a series of custom medical products. Various products will have different functions and features; however, a single multi-function PCB will be used for the entire product family. The PCB must excite and condition signals from (4) precision load cells and then convert this data into computed metrics and stream the results to a host computer over USB and optional Bluetooth. The PCB must also drive an optional auxiliary user interface consisting of a custom membrane switch with LED indicators and LCD display for certain stand-alone product functions. 24-bit ADC with simultaneous sample and hold of 4 single ended channels at 100 Hz minimum sampling frequency is required. The MC must be capable of streaming the computed values continuously in near real time...

I am looking to have designed a small electronics system. The system will consist of a simple timer with user interface, a micro-controller, a light sensor, and a small speaker and LED light to serve as an alarm. The electronics will be implemented into a small plastic and/or glass product. This product is to be used in the following manner: -The user will enter a time (possibly hours and/or days), this timer will then count down. After the timer reaches 0, the speaker will sound a "beep" and a light will flash only after the light sensor detects a significant amount of light. The product will be kept in a dark place 99% of the time and will be in light after the user physically turns a light on. The idea is for the product to sound an alarm after the set time AND after the light sensor detects a significant amount of light. At this stage, I am looking for this small electronics circuit to be designed for a prototype plastic/glass product. I am also looking for advic...
