I am looking for a freelancer to help me develop an I2C to RS485 interface for the MODBUS RTU protocol. Microcontroller: No specific microcontroller has been chosen for this project, but I have a preferred microcontroller brand. However, I am open to suggestions from the freelancer. Noise Immunity: The project requires a high level of noise immunity to ensure reliable communication between the I2C and RS485 interfaces. Ideal Skills and Experience: - Proficiency in microcontroller programming and communication protocols (I2C, RS485, MODBUS RTU) - Knowledge and experience with various microcontroller brands and their capabilities - Familiarity with EEPROM usage and implementation - Expertise in designing circuits with high noise immunity - Ability to troubleshoot and debug communication issues - Detail-oriented and thorough in testing and validation processes Desired Interface Operation An existing equipment only has I2C serial communications available, but I need this equipment to provide data to, and be controlled by other equipment with only MODBUS RTU serial communications available. This existing equipment will always be a slave, there is no scenario where it will need to control other equipment. In other words, other equipment react to data from this equipment to control it. Please note that for cybersecurity purposes, the entire project files including source codes are required, and project kits based on Arduino and Raspberry Pi may be used for development purposes, but the source code must be transferrable to industry-hardened microcontrollers.

@bsarevalo

Hello ! I am very interested in working on the project, my experience in embedded systems is wide, Expressif (ESP32, ESP82), Atmel Atmega (Arduino nano, mega, uno...), STM32, Microchip. I think that even the simplest microcontroller can perform the task of converting the input data by I2C communication to modbus RS485 RTU without any difficulty. My experience in industrial communications and integration is extensive so I can demonstrate my experience in the field, I can send you screenshots with Modbus, Master - Slave simulators integrated into a microcontroller installed on my breadboard and sending data through the serial port to the PC. I can easily assimilate the data that you need to store in the EEPROM, likewise create programming routines that prolong the useful life of the EEPROM Write & Read. I hope my offer is of interest and I am available to share some of my previous projects to confirm my experience in this!

My plan is to deliver you a complete product that you are in need of. I have been living with Modbus protocol for around 5+ years (Yes, I design industrial products where many Sensors/PLCs/Energy Meters are connected via RS485 and Modbus). Will initially develop and test the product on the resources I have and then final product as per your physical spec you might have. Planning to use STM32 series MCU which are easily available and cheaper in costs. However, I am open to use any MCU if you already have a plan or you use on other products (managing supply would be easier for you then). Have got more than 25 years of programming experience and over 30 years in electronics. Price is a bit more than your price bracket as I have plan to build the prototype of the actual hardware for final inspection before delivery. I wont charge extra for that. Let's get connected if you are interested. Full confidentiality will be adhered and all the design files as well as sources will be delivered to you. Thank you for your time and I look forward to hearing from you. Best Regards... Roy

@anatol33

Hello. My expertise is up to the project, I have sufficient experience with I2C, RS485 protocols. My vision of the hardware is some microcontroller with I2C interface plus some RS485 shield. The source code would be in Arduino, it is exported easily to .bin files. Is it what do you mean as "transferrable to industry-hardened microcontrollers"? My main concern: for debugging I need probably to have the equipment you use at both master and slave ends, otherwise the project may become a long story, so would you clarify this point? At least technical descriptions with data formats would go for the start, so I would better understand the task. About me: I'm an electronic engineer with about 25 years of experience, also about 7 years of experience in 3D modelling using SolidWorks. Experience with Arduino and ESP32 controllers. Good technical background. Experience in 3D printing, manufacturing drawings. Prototyping is possible, both electronics and mechanics. Currently live in Germany. I'm ready to discuss details by messaging before starting, contact me if interested. Best regards Anatolii

I am Danish, Electronics has always been my passion and i love discovering new things and creating new things. I have 12 years of experience creating products with active input from design to the delivery covering all aspects from hardware to software. I have made an industrial gateway for communication with modbus RTU slaves and sending that data over MQTT to servers for remote monitoring. This product is used in industries, infact there is a scenario where is was used because the wired connection for modbus rtu was picking up too much noise. This product i made was developed on ESP32 with esp-idf and freertos as the os. I can support you with OTA firmware update, remote configuration of the device, as well as seemless communication from your modbus master to the IIC device. I have ample experience with IIC communication infact the product i just mentioned uses IIC for RTC and Display. Please message me so that i can show you the product as well as the level of skill i have.
