Esp32 or esp8266 with TTl to Rs 485 modbus rtu

Hello! I already worked on modbus RTU program on esp32 to read specific resistor or group of resistores from controller..

Hello, I have working code for esp8266 and esp32 to read/write registers. I can help you for this and also provide connection diagram.

Greetings thanks for posting the project there i am electrical engineer i have expertise in embedded firmware development, PCB designing and circuit designing.

You can trust on me; your satisfaction will be my priority. Looking forward at your earliest response. Best Regards Muhammad Adeel

I have done modbus reading using esp32 and rs485. Basically I was using ttl to rs485 converter board.

Hi, I can support on this. I am from Chennai. Can you provide the details of the MODBUS device you want to read the data? Do you have the ESP32 and RS485 convertor with you? We can discuss regards Senthil Chennai

Hi there, I am Ahmed an embedded systems developer. I have read your project requirements and I understand that you want to use esp8266 to read modbus rtu holding registers, with the help of a ttl-rs485 converter. I have worked on a very similar project and I gained a very good experience with modbus. I have a solid background in programming with python and C/C++, and I worked on several prototyping projects that are based on Arduino, esp's and raspberry pi. contact me over chat with more details on your project. I hope to hear from you soon.

I can help you out. Iam very Inthiosit to work on challenging thing's Don't hesitate to contact me.
