Wire char working and not

Projects Programming

Hello all.

Looking at the example from Arduino libraries master_reader.

I took the example provided and as writen it seems to work until I try the Serial.print(c) outside the brackets.

Code slightly modified. line 1, 11, 17-20

1   char c;
2   
3   #include <Wire.h>
4   
5   void setup() {
6     Wire.begin();        // join i2c bus (address optional for master)
7     Serial.begin(57600);  // start serial for output
8   }
9
10  void loop() {
11   Wire.requestFrom(11, 9);    // request 6 bytes from slave device #8
12
13   while (Wire.available()) { // slave may send less than requested
14      char c = Wire.read(); // receive a byte as character
15      Serial.print(c);         // print the character
16    }
17    Serial.println();
18    Serial.println('c');
19    Serial.println(c);
20    Serial.println('d');
21
22    delay(500);
23  }

If I run serial monitor now I don't get any printout for line 19. Why is that?

Thanks for the input.

c of line 19 is defaulted to 0.

This c is not the same c that was declared in line 14

Got it figured out.

Thanks
