STM32 & ESP32 Firmware for Multi RS485 to TCP/IP Modbus Gateway
Budget: ₹1,500 – ₹12,500 INR
I'm seeking an experienced firmware developer to create software for a RS485 to Modbus TCP/IP converter. This system will handle two RS485 inputs, each connected to 8 devices, merging their data for Ethernet transmission.
Key requirements:
- Data merging from two RS485 inputs
- Sending data over TCP/IP using Modbus TCP
- Handling of two RS485 inputs with 8 devices each
The devices on the RS485 inputs will use the Modbus RTU protocol, so familiarity with this protocol is essential. The data types and signals are mixed, including both sensor data and control signals, which requires a versatile and robust approach to data handling.
Ideal candidates should have:
- Proven experience with STM32 and ESP32 microcontrollers
- Deep understanding of Modbus protocols
- Strong background in firmware development
- Skills in data merging and TCP/IP transmission
Please be prepared to share relevant past project examples.
