Hi Parth, @parth kothiya

I'm using an stm32l433 and I also want to communicate using modbus without RTOS.

Do you have a standard library interfaced with STM32 ?

regards.

[parth kothiya]

no standard library i found.

But there is an examples on git hub for modbus master and slave devices or you can also use arduino modbus code for your reference and write your own code.

arduino modbus library also available on github or you can direct search on internet.

Can you share some of these links? I don't find useful examples on github for arduino...

Thanks

I have written a book on Modbus slave design using C targeted to STM32: https://www.amazon.com/dp/B086PNZF4W
