Currently, this code takes up nearly 50 % of the Atmel 328p memory! and a lot of Dynamic memory. (over 50%) I have removed TCP support since that was not...
I've been reading [this good article](https://www.stderr.nl/Blog/Hardware/Electronics/Arduino/ModbusLibrary.html). He's been testing some libraries across the web and make some good comparison points. Let me quote some for this particular library: > https://github.com/arduino-libraries/ArduinoModbus...
I am using the library to create a modbus-rtu slave device that has more than 50 holding registers. The master device tries to write to all the holding registers in...

Not exactly sure if this qualifies. I have a loop that steps through reading a bunch of inputs. The first run through works perfectly I do one requestFrom() and then...
Hi there. I have gotten this library running with a modified example. My ESP32 is a modbus TCP server and is getting polled from my PC using SimplyModbus software. This...
I'm using an Arduino mega 2560 as a slave on rs485 networks where the master is pc with a python script on baudrate 115200 the ArduinoModbus is working fine with...
Hi, I have a question about the start address of the coil. Should it be always 0x00? If I change it to a different address, I am getting the '02...
With memory being tight on most micro controllers, I felt like I shouldn't have to allocate memory for Modbus to use, but instead point the server at existing data structures....
