I'm trying to see the character string in Hyperterminal

0 votes

Hello everyone.

I am trying to simplify the example to be able to see the string of characters sent to me by the camera, first for T2 and then for N2.

The program modified:

 #include <Servo.h>
  
 #define SERIAL Serial
 #define INLEN 128

 char instr[INLEN + 1];

  void setup()
 {
   Serial.begin(115200);
   Serial.setTimeout(1000000);
   Serial.println("setpar serlog None");
   Serial.println("setpar serout Hard");
   }
 
  void loop()
  {
   byte len = Serial.readBytesUntil('\n', instr, INLEN);

   instr[len] = 0;
   Serial.println(instr);
   delay(50);

    }

When I compile and load the program in the arduino UNO, the result in the Hyperterminal is the following:

setpar serlog None
setpar serout Hard
T2 61 -123

T2 61 -122

ERR Unsupported command [T2 61 -123]

ERT2 50 -123

T2 48 -123

My question is this: Why is "ERR Unsupported command"?

Now I have included the line: "setpar serstyle Normal" in the file: initscript.cfg

setmapping2 YUYV 320 240 30.0 JeVois DemoArUco
setpar serout Hard
setpar serstyle Normal
streamon

And the result of running the program is as follows:

setpar serlog None
setpar serout Hard

What should I do to correct this error?​

Thank you!.

Oh, when your arduino runs

 Serial.println(instr);

It is sending instr to the command line interface of jevois. Jevois tries to understand the contents of the string as a command. But T2 is not a valid command, hence the error.

Usually, you would use another port on the arduino to communicate debugging messages to you, not the same as it uses to communicate with jevois. Since you only have 1 hardware serial on the Uno, you can try this: add a # in front of your string. When jevois receives it, it will ignore it as being a comment. So

Serial.print(“# “);

Serial.println(instr);
