    We have a Solar Charge Controller design which we need modified. The existing design is solid but we need some changes and then I need the PCB layout redone. Basic information on the existing charge controller is:1.Microprocessor based2.PWM Charge controller3.Load switch - MOSFET4.Current Measurement (in battery circuit) – ADC into microprocessor 5.Voltage measurement – ADC into microprocessor6.Temperature measurement – ADC into microprocessor7.USB communication8.iButton communication9.E2 memory10.RTC Date CalendarThe new charge controller is to have similar functions with the following additions:1.Additional current measurement in the load circuit - ADC2.Bluetooth connectivity3.Keypad connectivity.4.Minor changes/modifications - TBAYour responsibility will be to:1.Analyse the existing design and ensure you understand it completely.2.Do the new electronic design and simulation in Proteus 8.0. The design is to include the calculation of the A2D factors and calibration methodology.3.Once the design has been approved you will be required to do the PCB layout. Note that the PCB layout will be for two PCB’s. The first PCB will be the microprocessor and its associated components (low power) and the second PCB will be the MOSFETs, heatsink etc (power components). The two boards will be joined through a ribbon cable. Gerber files are to be provided. The PCB’s will be double sided. Surface Mount Technology will be used.4.Component list with suitable alternatives where necessary.You will NOT be required to:1.Do any microprocessor programming. We will provide the micro specification and pin layout.2.Make prototypes.A more detailed specification and the existing design will be provided once a NDA has been signed. For now please provide a cost per hour, experience, plus estimate of hours. We will fine tune once a full spec has been provided.Also note that this is an extremely urgent project. Please indicate resource availability and estimated time.

    I have Altuim and PADS based design files that need a production modification to the power supply and a new board layout generated.We need a quick turn on the job. The board is 6 layer, 16MM max width by 50MM - 70MM length.We have numerous variations however the this project will just cover one production ready prototype.I need revised schematics, BOM, PCB files, and Gerbers.A 3D model would be helpful if able.

    Need a program written for a mc9s12c32 micro-controller using assembly. Explicit instructions are attached. Feel free to ask any questions.

  • $100 USD 14 days ago

    I have an assembly program that was originally written for the PIC16F690. It takes serial data in, process a specific number of bytes, and convert it to an I2C stream to a Master. I need someone to update this code to a PIC18F that has more RAM and is much faster, and in the mean time, process three times more bytes.

    Module should be defined like this:module divider( output[7:0] q, output[7:0] r, input[7:0] a, b);// a = b * q + rOne of the implementations should use Newton–Raphson method and the second one should use Goldschmidt method.Both methods should be 100% functional and both simulations must be functional and return the right values of q and r.Would be great if you can also comment the source code.

    I need someone to make the design, layout, advice on components of a piece of electrocic and if possible make a prototype.I have some knowladge about electronics but not enough for this kind of project.I prefer PIC as the microprocessor.What I need is simple: the hardware will take as input an audio signal, will make a Zero Crossing Rate and save the output on a micro SD card.The hardware will always make the ZCR once per minute during 15 seconds.It is an easy project for someone who has solid backgroud in electronics.I need you too to program the pic.So in all, I need a ready made solution, I can make the production of the prototype by myself.
