Official Arduino Modbus RTU library and Controllino Mega

[Lukas]

Hi,

I think that you have done only one small mistake – please try to replace

Code:

CONTROLLINO_UART_TX

with

Code:

CONTROLLINO_RS485_TX

.

And it is also necessary to add

Code:

#include

at the top of the RS485.cpp.

I will try to prepare the setup and test it here also.

Good luck!

Lukas

Thanks, it is working.

Could you paste all the modifications required for the ArduinoModbus library to make it work for a Controllino board.

I didn’t understand the part

” #include

-at the top of the RS485.cpp”

Which library should be included at the top of RS485.cpp?
