This is a commercial product development for an established company. The project is firmware only and requires exceptional skills and experience with Arduino, C and C++. Specific requirements include: SPI (master and slave), Arduino/AVR interrupts, optimisation for very low power consumption (sleep modes and wake from interrupts), analogue sensor reading, pulse counting and SDI-12 interface (experience welcome but not essential, it’s a fairly simple protocol for anyone experienced with serial protocols). Fast worker with provable track record. The device is a multiple sensor input to SPI slave device. SPI commands from a master device (separate project) reads data from the slave previously collected on configurable schedule. In addition to the main project effort, simple code that can run on another Arduino to test the slave device firmware will be required, basically a com port text to SPI translator that acts as a master and allows text commands at the terminal to be interpreted into SPI commands and return responses from the slave device. Development can be done on an Arduino Uno but is ultimately for custom target device that will be used beyond the Arduino community. The use of Arduino architecture is only to speed development. This project requires very fast and efficient work. If you don’t have significant time to dedicate to this project, please do not apply. This is also the first part of 3 firmware projects (and possibly ongoing work) that also includes XBee and cellular interface requirements. A successful candidate who also proves capable, willing, easy to work with and efficient with this project will be given first refusal on the following two projects. Access to detailed specs. via Google Docs will be given to suitable candidates.

Hi, I wish this could be required with PIC micro controller instead of Arduino. The same result could be achieved (or may be better) with PIC MCU too. I have 25+ years of experience in electronics and 17+ years in C programming. Actually I dont like that Arduino layer that undauntedly slows down the process. Please let me know in case if you can use PIC micro controller instead of an AVR based Arduino. Thank you for your time and I am looking forward to hear from you. Regards... Roy

Let me help you with this project. You can have a look in my portfolio and over my feedback and you will see that I can do your project. I can do it using arduino platform or Atmel Studio. A SPI Slave will has 4 pins MISO,MOSI,SCK and CS, the master need to access each slave using particular CS pin let me know more about what you need to read, and how need to look the SPI protocol (commands, data types, length) "The device is a multiple sensor input to SPI slave device." How many inputs and which types I see that you have analogue, pulses and also SDI-12 interfaced

I have 12 years of design and development experience in the field of embedded systems. What I understand is that you want to control the SPI based devices using a com port. I have a lot of experience in PIC and aurdino controller. I can do your first part, you can review my profile for more information. Thanks.

Hi there I can do it. Im Telecommunication engineer (5 years of subjects including electronic,etc). I can help you with this project. I have developed a lot of projects with Arduino before. I program directly from datasheet (interrupts, registers, flags, etc) and cand program all kind of periferic with the better optimization time-response. Serial RX and TX interrupts in order not to stop micro while printing, ADC interrupts too avoiding wait for ADC finish(like the analogRead), timers,etc. Also i have a lot of Arduinos to build a prototype here with me including the slave-device. I own a bunch of Arduinos UNO, megas, Due, shields, sensors, etc. I can show you some samples if you want to test my skills. Also you can check my reviews from other employeers. Message me and we can talk about the project. Regards.Greg.

I am a serious bidder, accepting only projects I am sure I can complete at a 100%. I am bidding with a 30 day time to complete only because I don't know how many and what type of sensors are you using and how the data from the sensors should be interpreted and passed to the SPI master. It may take a lot shorter time. If you like my offer please send me more information about your project, so I have better understanding of what is needed from me. Thank you

Hi, The scope seems to be huge, I am interested in because of the challenge it has got it. From the description its clear that there are three parts of work, I would like to know whats the first work is about, based on that the due time may increase or decrease. I have well exp in embedded system with different controller. Check my profile for it. Looking forward to hear from you.

I' am experienced embedded system engineer, and I have extensive experience with AVR MCUs. I worked with ATtiny12,15,26,85, ATMega8535,644,128, 48/88/168/328, 1281. I developed both high-optimized assembly-level code within C/C++ code and hardware. I worked with all available peripheral of an AVR MCUs Can do successfully your project on any kit like Arduino Uno or anything else. Also can develop customized hardware for your project. See my portfolio on Freelancer.com What is your target AVR MCU ?

Hello! I am new at this web site. I am software Engineer for uE, i have a very good experience with AVR Atmel uEs and i am working for a couple of years with Arduino, i can program better with native C and i think this is better for your system. If you look my profile, i have posted some link with my blog, there you can see my last project and of course you can see that i have made a API for my board, this API works like Arduino API. Your sincerely Tosis Nikolaos

I have already done extensive work on arduino Uno, mega. Have worked on I2C and SPI technology. My basis come from 8051 microcontroller where I first implemented a RTC with SPI enabled registers. The background extended to assembly language coding once I had the grip on the MPLAB IDE. Have done work on MikroC also. After doing assembly jumped to the Arduino IDE to see what all the fuzz was about. Arduino seemed like an extension from the Java land so loved it. Currently making a Project based on RPI and Arduino Flight Controller, making a quadcopter which can be autonomously used to survey an area. If you are interested please hit me up!
