Hello I am sending a string data to Arduino from matlab using the following code.
clear s;
s=serial('COM4','BAUD', 9600); % Make sure the baud rate and COM port is
fopen(s);
value1=('11,222;333<444>555?666');
display('data sent');
fprintf(s,'%s\n',value1);
fclose(s);
I am receiving and processing the string in arduino using the following code
String command;
int i;
float data_rec;
void setup() {
// put your setup code here, to run once:
command="11,222;333<444>555?666";
Serial.begin(9600);
}
void loop() {
if(Serial.available() >0){
String command=Serial.readString();
// char c=Serial.read();
//if(c == '\n'){
parseCommand(command);
data_rec=Serial.parseInt();
Serial.println("data_rec");
Serial.println(data_rec);
//}
}
}
void parseCommand(String com){
String F_d;
String E_m;
String L_p;
String S_v;
String H_d;
String L_t;
F_d=com.substring(0,com.indexOf(','));
E_m=com.substring(com.indexOf(',')+1,com.indexOf(';'));
L_p=com.substring(com.indexOf(';')+1,com.indexOf('<'));
S_v=com.substring(com.indexOf('<')+1,com.indexOf('>'));
H_d=com.substring(com.indexOf('>')+1,com.indexOf('?'));
L_t=com.substring(com.indexOf('?')+1,com.length());
Serial.println(com);
Serial.println("F_d:");
Serial.println(F_d);
Serial.println("E_m:");
Serial.println(E_m);
Serial.println("L_p:");
Serial.println(L_p);
Serial.println("S_v:");
Serial.println(S_v);
Serial.println("H_d:");
Serial.println(H_d);
Serial.println("L_t:");
Serial.println(L_t);
}
This does not work with Matlab.,
However when I send the same string from the Serial Monitor, it seems to work.
Why ain't I getting any output for the matlab code?
I am checking the data sent and received by arduino over serial by monitoring the serial port using Serial Monitoring Studio.
