My objective is my master (Microcontroller) want to read the read holding register from socomec energy meter. Here i am using the RS232 to Rs485 conversion, but i didn't get any acknowledgement. I send the data from my master to slave like this....
data("0x05");data("0x03");data("0xc5");data("0x52");data("0x02");
IS there any mistake in this? Is I2C is needed for this communication?
data("0x05");data("0x03");data("0xc5");data("0x52");data("0x02");
