Hey guys, i have a project where i am trying to use an arduino mega, to connect over modbus rtu using serial port 1 or serial port 2 of the mega, 9600 baud to a client that is addressed as 1. The hex value of the register is 13. How can I just send this value repeatedly to my device.
I am running the latest version of modbusmaster, inside IDE 1.8.15
Can someone provide an example, this has to be super easy, but I am not seeing how to write this 8 bit value. The type is a uint8_t
Also does this library do the built in checksums for you?
Thanks again, sorry for the strange question. I have experience with modbus but only with something designed to communicate with it already.
ModbusMaster version
[Version of the project where you are encountering the issue]
Arduino IDE version
[Version of Arduino IDE in your environment]

Scenario:
[What you are trying to achieve and you can't?]
Steps to Reproduce:
[If you are filing an issue what are the things we need to do in order to repro your problem? How are you using this project or any resources it includes?]
Expected Result:
[What are you expecting to happen as the consequence of above reproduction steps?]
Actual Result:
[What actually happens after the reproduction steps? Include the error output or a link to a gist if possible.]
