PCB including a PIC and development of the software. The board project is for a Fuel Dispenser . 1) A 1" backlit (LED) lcd Display capable of counting up to 999.99 plus the option to fit a further display as a slave 2) A selectable Pulse output either 10 pulses per Litre or 100 pulses per Litre,also rs485/rs232 serial interface control/monitor 3) The display resets to 000.00 when a reset switch is activated(low voltage) and a 240volt single phase motor starts up 4) On Board PSU 5) Digitally displayed totaliser readings 6) capable of using a single channel or duel channel pulser for the input 7) Capable of entering a mode to calibrate the dispenser by counting the pulses when 20 litres is dispensed into a calibrated measure ,Then when the fuel is dispensed the PCB displays the correct quantity of fuel dispensed example: ie if it counts 2000 pulses in then it knows when it see's 100 pulses ,1litre has been dispensed 8) The board is development proof ,future needs to be capable of networking, link using a serial protocol 9) Based around a PIC chip

For the above offer to be valid, after the following questions are answered. 1) Do you need the whole design of the PCB? (i.e. including the layout) 2) What is the model of the PIC you are using? 3) How much work do you exactly need with the circuit setup? Subject to questions '1' and '3' the time frame and the fee may vary. Best regards

Hi, I have discussed your project with my team of IC engineers and they have two technical doubts. Before finalizing on the timeline of the delivery of the project we need to clarify this doubt. We have done the costing and we will be able to provide you at cost lower then $750/-. So if possible kindly contact us in personal on my msn live id hmdesai1980 Warm Regards, Hrushikesh Desai M: +91 96012 61160

Your specification is unclear in some areas and the questions posted have not been answered. In order to bid we will make the following assumptions, the correct answers to which may reduce (or increase) the quotation price. You state LED and LCD, we will assume you mean LED. We assume that: The flow (and hence pulse) rate, is less than 100lpm i.e. <166pps. The on-board PSU derives its power from the mains with a universal input 90-250Vac 50-60Hz You will provide a specification of the serial protocol used, or provide a sample of the output data. Deliverables: Electronic design Software PCB design Physical PCB Assembled, tested prototype Design documentation, simple user manual Time to delivery 20 days, it can be less by up to 5 days if you are willing to pay more for the PCB. Although I am *VERY* familier with the PIC chip, personally I would not choose it for this project. Is there a definate reason why you need to use a PIC? There are much better designed and much more capable microcontrollers in existance, e.g. MSP430 or LPC, both of which have much better free development tools available. Unlike the PIC, These processors have a proper CPU architecture and as such they are much faster to write software for, time is money if I can write the software faster I can reduce the cost to you. About us: Our company is an electronics design consultancy based in the UK. We are a UK limited company and offer design consultancy in microprocessor, analogue, high speed digital, FPGA and DSP systems. We also undertake electromechanical development including plastic injection moulded part design. Our in-house EDA tool is Altium Designer and we have standard lab equipment at our disposal as well as SMT assembly and rework facilities. We use Pro/Engineer Wildfire for mechanical design. We are affiliated with a contract manufacturer for small to large volume production. About me: I am the director and principle engineer within the company. As a trained electronics engineer I have 18 years experience as a professional and 15 years experience in electronics prior to that as a hobbyist. I am experienced in microprocessor system design, high speed digital design, analogue electronics, FPGA and DSP as well as software from low level assembly language to high level C , Delphi & python.
