Raspberry Pi IO to Ethernet

I have +10 years of experience in Python programming. I have worked with Raspberry PI on some projects. It would be simple task for me to read and send those digital inputs to any computer. I can implement centeral computer server application myself too if you are interested;) We can start the work as soon as your provide more details. Thanks, Helmot

Hi Sir/Madam. I'm expert in Python programming and I have experience with integrating various sensors on RPi. Can You share some more details on the project? Best regards, Fejs.

Hello, I have been using Python for over 5 years for most of my programming needs; I have written web applications, administration scripts, SMS gateways, data crunching applications and others using Python. Regarding Linux I'm using it for more than 8 years on both desktops and servers. I have 4 Raspberry PIs at home that I use for web hosting (personal projects), file server, video surveillance, home automation (including DI, DO, EnOcean devices), motor control. To be honest 750-1500 USD seems too high for an application that reads the inputs and sends the result to a server. Can you give me more details about your project? Thank you for your time! Best wishes, Ionut

Hello Dear, I can do this for you. Please send a massage in the PMB for details.......Best Regards flashsaiful

Hi, I have already worked on similar project on Raspberry pi platform that will scan input pins and will send the status back to central server. This can be implemented in several ways. I have ready to use Raspberry pi image that can be customized to match with this requirement. The Raspberry pi can have unique IDs to identify itself. We can create communication stack between Pi to central server to communicate either way. I have also worked on the center server coding project, that will show collected data in HTML format (or some other form) . Thanks!

Hello, I am a professional C++/Python developer for over 3 years mainly involved in Intelligent Transportation Systems. In my work I often gather and transfer data from many diffrent sensors and for that we sometimes use RPi and its interfaces like SPI or UART. If you still interested in hire a freelancer I am available. I would also ask you about few things. What kind of digital interface would you like to monitor. Is it I2C, SPI, UART or maybe just GPIO ? The next thing what model version of RPi do you have ? Do you need only one way or two ways communication ? Regards, Marek

I can prepare a prototype that will do exactly what you require. if you need more detail I can prepare diagram, but need more information on what data to collect and to send.

Hi, I'm experienced in embedded programming. I used boars like MSP430, UDOO, ARDUINO, PIC, RaspberrPi. I made projects about USB, RS-232, UART, SPI, I2C. I worked in projects like fingerprint scanner, smart parking system, remote camera control, ftp server, using REST api. I used GSM, Wifi, 3G, google api, canon api, camera, servo modules etc. I can start immediately. With regards, Murat Torun

I will do a python script that read a config file where you put: 1.- IP of the central computer 2.- A name for the Raspberry (to identify in the central computer) 3.- a pair pin_number:port_direction (in/out) 4.- Time between IO ports readings And send to the central computer the results in a JSON format {raspberry_name: Name, ip:ip_address, pin_configurations: xxxxxx, pin_status: { pinumber:status, pinnumber:status, } ... ... }

Hi, my name is Dennis, I'm a Telecommunications Engineer, but now I work as a senior web developer on https://ciancoders.com. As my background is in electronics and I'm proficient in many programming languages, including python, I'm shure I can make the software for the raspberry and for the central computer. I would like to know more about the specs of the central computer software, if it already exists or has to be done. I could make the project for less than $500 but I would like to talk to you first. Cheers. Dennis

Hi there! I have extensive experience with the Raspberry Pi (A, A+, B, B+) and have written an umber of different pieces of software to run on it, including customising the kernel for using specific hardware. I am not a python developer however, and your project is tagged with only python so perhaps I am not a good fit, but I can create anything you might like in C++ just as easily. With regards to the specifics of the project, sending data over ethernet network is quite straightforward and I know exactly how to read digital data input from the Raspberry Pi's GPIO pins, so it should be a relatively straightforward matter of collating that data and broadcasting it over the network. This could be done one of two ways - either with a TCP connection to the central server that ensures no packet loss, or using UDP broadcasts to communicate with the central server if it's host IP is not known - both of which I have experience doing on Raspbian. I look forward to working on this project with you, and believe we can accomplish this task in three days or under. Please don't hesitate to send me a message with any questions you may have. Have a great day! Chris

Hello , I am a senior in developpement in perl , python and in many others language . I am a senior in linux administration . I can work on your project . I have already work in this kind of environnment https://www.freelancer.com/projects/Perl-Software-Architecture/Datacollection-raspberry-with-rrdtool/

I've coded the raspberry pi for data logger applications in which it takes data from a sensor, save this data in the SD memory and then sends it to a central server over multicast IP. All this was written in python. So I get the code for do the job you want. I only need your particular requirements to customize the libraries from my personal resources

I have completed a similar project for a similar application, so porting it for you is a trivial task, you can drop me a Msg to ask about any doubts you might have, I might also do the job for far less, maybe like 200 dollars or something

A proposal has not yet been provided

Hello Please tell me more about your digital inputs and requirements. How fast they are changing, what are your expectation of response time? I have solid experience in backend/system/low level development for Linux. I own 2 Raspberries ( old one model B+ and new multicore Raspbberry Pi2). Regards, Kostyantyn

hi I have done exactly same project in 2014 that is serial to Ethernet bridge using raspberry pi and the language I used was C. Details about the projects: achieved full Duplex communication without any waiting for inputs using threads. Serial devices at one end which i interface using UART. For ethernet i used UDP protocol. serial device i used is RFID reader. I have working C code for this project and no doubt i can convert it in Python as well. If anything bothers you we can have discussion over it, ping me back so that i can showcase you the work if you want to be sure about me. Thanks Dinesh

Hi, I am Laszlo Benke, from Hungary. I am an electrical engineer. I work as a C# and PLC developer. I am dealing with home-automation and RFID systems. I know the raspberry PI platform well. I made a home-automation system for myself. This can control the heating-water and air-conditioning and function as a burglar alarm system. You can control remotely, via mobile or web-browser. I know the Raspbian (Debian Linux), Apache, Web and Python technologies as well. I have Raspberry PI B+ and Raspberry PI 2 and a lot of additional hardware too. Can you send me details? Please see my portfolio, it is about my freelancer and face-to-face experience. Thanks. Best regards, Laszlo Benke
