Parsing a message through serial using photon's TX/RX pins

[pres_10]

Good morning everyone,

I hope this message finds you well, yesterday a friend and I decided to take incoming strings such as “#L 80 45 23” and parse the data to where 80, 45, and 23 can be saved into variables and can be sent off in the “Particle.variable()” function. I’ve been working on a solution however for some reason, I’m not getting the numbers I’ve planned out to receive. Can someone help me out, or help me feel in the blanks?

My setup: There is an arduino that is sending “#L (random number set) (random number set) (random number set)” and also " #P (random number set) " through serial using the Serial1 port on the photon. I’m currently using the Stream class to parse this data.

My code so far:

while(Serial1.available() > 0) {     // The code is now running through TX/RX
     if(Serial1.read() == '#') {
       delay(10);
       char inbyte = Serial1.read(); // This is where the space is being discared
       //Serial.print(inbyte);

       int cvt;
       int cvtt;
       String foundData;
       int laneSize = 4;
       int LANE[laneSize];


         switch(inbyte) {

           case 'P':
           foundData = Serial1.readStringUntil('\r');
           cvtt = foundData.toInt();
           break;

           case 'L':
           for(int i = 0; i < 3; ++i) {
             foundData = Serial1.readStringUntil('\r');
             cvt = foundData.toInt();
             LANE[i] = cvt;
           }
           Serial.println(LANE[0]);
           break;
       }
    }

  }

Have you read this tutorial?

Serial Tutorial

Serial tutorial More than you ever wanted to know about serial communications with the Particle Photon and Electron. Updates to this document are here: [https://github.com/rickkas7/serial_tutorial] (https://github.com/rickkas7/serial_tutorial) USB serial The USB serial provides a way for the Photon/Electron to send data to the computer across the USB connection. Often this is used for debugging messages. For example: int counter = 0; void setup() { Serial.begin(9600); } void loop() { Ser…

@nrobinson2000 I have. That tutorial actually got me started, however I’m still have troubles.

Are you at least getting a string from the Arduino?

What troubles? You should say what result your current code gives, rather than telling us it isn’t giving you what you want; that would be more helpful in diagnosing your problem.

Here is the results I’m getting back from the serial:

This is what I’m receiving from the arduino:
