I am looking for someone to produce code for a microcontroller which is to act as a node in a wireless mesh network. The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

I am looking fro someone to design and program an HMI for a wireless mesh network node. The node will have a 2.4" touch screen with an SPI interface. The user will be able to select either one of two fixed channels (Channel 1 and Channel 2) or a third 'Home' Channel which would be selected by the user from a list of available channels. The menu structure is envisiged to be something like as follows: Page 1: Button to Select either Channel 1, 2 or Home Channel. Page 2 (or popup): Ability to set a channel as the home channel or select a fourth channel for listening. Menu structure as: Menu Level 1 (Nine options) - Menu Level 2 (Max 50 options) - Menu Level 3 (Max 20 options) The names for each Menu level or Channel would need to be editable and updatable by a remote connection so this needs to be borne in mind when programming. The graphics do not need to be fancy and a simple, clean, user-friendly interface is preferred. The processor would need to be an Arm Corte...

The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. In any one network cell there would be a maximum of 10 selectable channels by a total of approximately 5,000 users. Each audio channel would be multicast over this network. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

Dear all, I need some help in translating the drawing models (*.dxf) from curves into surfaces in AutoCAD. Please check the attached powerpoint, the main target is to create a guiding procedure in AutoCAD to extract and repair curves (if necessary), then generate a corresponding surface based on input parameters such diameter and angle, and finally export the results to CATIA. Of course, user interfaces are nice to have. But, this don't need to be perfect, I just need a simple prototype at this stage. If this goes well, then more could be just continued. Please kindly let me know if any information you may want to know. Thanks.

We are developing a new kind of "Walking Desk", faster, more effective and more simple for the user. For this, we are using an arduino card and a touch screen, the SPARK CORE and the adafruit HX8357, specifically. We need someone that can manage with all our specifications of this new prototype. We need someone with both programming and creative skills. The idea is to have a code to control a treadmill with the basic functions, start, stop, +speed, -speed and some other specifications. All this, controlled by the user through out the touch screen interface. The interface is also an important thing while working in a product that is going to be used by people. It has to be creative and attractive to human eyes. Is an interesting project and there are possibilities for you to continue working with us. So if you want to know more about this, send your resumes!! We will have a quick answer for you Is important to now something about the SPARK CORE !

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...

ZeeVee manufactures translation devices for video. These are small devices (about 4"x7"x1") that usually reside near television or near a video source. In many cases users want to rack the devices up densely in a 19" rack. I need a rack cage, and brackets designed to hold the individual devices in that cage. There are probably 2 or 3 pieces to design. Sheet metal is the medium. There are no unknowns as ZeeVee has models for all the devices to be mounted. Freelancer should have all tools required to generate a model and submission package for a sheet metal manufacturing house. ZeeVee will handle submission and interface to fabricator.

Design a Proof of Concept (POC) working prototype of a test chamber using Proportional Integral Derivative (PID) solution to digitally control the temperature, pressure, flow rate and volume independently. Generate a User Interface (UI) to monitor and regulate the above parameters via a PC/ tablet device. Test chamber will have pressure control valves at both the inlet and outlet to regulate the pressure differentials during operation. Finetune the PID control and UI system after POC prototype is built and tested.

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.

Seeking an engineer or engineering team to develop firmware from scratch in an extremely accelerated timeline for an existing Cortex-M0-based embedded system for use in battery-powered portable heating applications. The board itself features an I2C-connected small OLED display and various standard power regulating components. A user interface which can display and adjust parameters of the system as well as a menu system must be developed as the scope of the project, as well as designing and implementing complex RTD algorithms. More details of the project will be provided upon statement of intent by a potential bidder pending the completion of an NDA.
