Hello,
I am new to Arduino, and for my project, I need to read data from the holding registers of the LE-01MW power meter. Data from the register should be displayed on the serial monitor. For the microcontroller, I am using NORVI-GSM-A04-I, both the microcontroller and the power meter already have RS485 connectors. I have tried using codes found on the internet, but the data that I get in serial monitor is unreadable (squares as a result), I have tried changing the baud rate, but it is always the same. It would be appreciated if anybody had some examples of code for reading data from a power meter to a microcontroller. RX=3, TX=1, DE & RE = 4
