[SaeedNowroozi]

I want to read data from address 1, function 4, address reg ‫‪0x0000‬‬, 1 number, but not any action. float txf[8]; mmodbus_readInputRegisters32f(1, 0, 1, txf);

I don't have any device to test it. but as I can remember, I tested it before. Please debug step by step and see what is happening in the function and tell me. thanks.
