Which plugin is the best to start from? Using 2-way communication, send and receive.
For example the command to fetch the serial number of the connected device:
Code: Select all
byte stx[] = {0x02};
byte etx[] = {0x03};
byte ack[] = {0x06};
byte cmd1[] = {0x30, 0x34, 0x36, 0x34}; //0464 // Serial Number
byte cmd2[] = {0x30, 0x38, 0x36, 0x38}; //0868 // Unknown
byte cmd3[] = {0x30, 0x39, 0x36, 0x39}; //0969 // Operating time
mySerial.write(stx[0]);
mySerial.write(cmd1[0]);
mySerial.write(cmd1[1]);
mySerial.write(cmd1[2]);
mySerial.write(cmd1[3]);
mySerial.write(etx[0]);
Code: Select all
//============serial num=============//
void serial_num()
{
data_array[10] = 0; //terminate original string early
Serial.print("Serial number: ");
Serial.println(&data_array[2]);
}
void operating_time()
{
data_array[10] = 0; //terminate original string early
runningtime = strtoul(&data_array[2], NULL, 16);
Serial.println(runningtime); // in quarter seconds
Serial.print("Running Time: ");
float runningtimef = runningtime;
Serial.println(runningtimef / 4 / 60 / 60); // divide decimal number / 4 / 60 / 60 to get running time in hours
}
