I want some code written in Arduino C. Fully compatible with Arduino IDE. Made easy with standard library out there. Well commented and easy to read.
The function I want is a Master-Slave system over i2c standard, with the Atmega328 processor (Uno, nano and other compatible chips)
Function like this:
In the Master node:
I want a function that will send a variable (integer or byte) to a node in the system, I don’t know if it 255 possible nodes with i2c but I want to be able to address which I want. Payload and destination sent over the i2c bus to a slave node. The message sent over will be formatted like “Which variable, data for variable, node id” example 100,255,2. Variable 100, value 255, to node 2.
Also, I want to be able to send a request to a node as well, to return a variable the other way around. This will be in another function.
The most important thing is transparent function over RS232 to a terminal program, such as putty, docklight etc. So If I don’t make a main program in loop I want to be able to handle the commands over RS232 from a PC. So if a type in for example “S100,255,2” it will send the value of 123 to node 2. Preferable with an ACK. If I request something like “R100,2” it will give me the value of variable 100 from node 2…
In the Slave nodes:
This code will answer and send what the Master asks for and put the data into variables. Except of the interrupt routine bound to i2c protocol, I want a function to send data to the Master if it’s allowed on the bus. So if possible send “variable, data, from node” to master. Master will then put this out in the serial terminal as well.
Think I got the most important things written here, small tweaks and things that comes up we will work and solve together over chat. I don’t want any hardware only software for master and nodes (nodes will be same software just change the node id in sketch) please feel free to contact me for any questions about this. I made a simple picture of the basic setup between pc, master and slaves.
master slave i2c can be quite tricky, it does lock-up. i have about 20 arduinos so can build up a text kit. the serial parsing i have done before. would need a few i2c methods to accomplish this.
Relevant Skills and Experience
lots of arduino experience and have done lots of i2c work reading sensors , plus have all the required hardware to setup a proper test. keep working at it till it comes right.
Stay tuned, I'm is still working on this proposal.

Hello
I have experience in designing electronics circuits and can make your project. I will make your project practically on breadboard and will provide you circuit, code and PCB design along with gerber files. I will design your project using extra cheap and reliable components that will be beneficial for you if you are planning to make a commercial product.I also have experience in bluetooth modules and android apps development. I can also develop android app for you that will be able to control your project and you will be able to monitor your data. If you wish we can discuss in chat.
Thanks
With standard Arduino libraries, the project is quite simple but with limitation: address is 7 bit plus some reserved address per i2c standard so maximum you have 122 slaves only.
Relevant Skills and Experience
I2c is not designed for long range so not sure why you want so much devices? If you need longer range, other method make master and slave talk over wifi will be much better.
Proposed Milestones
kr1000 SEK - This is just the init value. It will be change after discussion
To have good proposal, I need to know the place you will apply this master-slave communication

Hello,
Hope you are doing great..!
I have carefully reviewed the requirement. I am very much interested in this project and would like to work with you on your important project.
Relevant Skills and Experience
Please have a look at my profile and portfolio to get an idea about our capabilities and some previous work on freelancer.
Proposed Milestones
kr888 SEK - This is approx. I’ll give you exact budget and price once discussing in details with you.
I am proficient in the following :
-> C programming language
-> Embedded C Programming
-> Arduino C using Atmel studio 7.0 compatible with Arduino IDE
-> Atmega using Atmel studio 7.0
-> Simulation using proteus
Communication Protocols :
-> I2C (TWI)
-> SPI
-> UART
I am working with Arduino by programming get the Atmega inside using Atmel studio 7.0 which will be compatible with Arduino IDE.
I made a great projects based on I2C communications and the functionality as you said in the description.
I2C requires :
-> robust communications
-> strictly following protocol in every step regarding initialization and sending get and receiving
-> modularity in design (it is a must)
I am also had :
-> Modular way of thinking which leads to modular design (Very important regarding readablilty)
-> very dynamic mind which is able to learn new things fast
So I am able to deliver your project at your high expected quality at a time.
If you choose, I think you won't regret.
Thanks
