Hi there!
I´m having this error:
In file included from HelloKeypad.cpp:11:
D:\Arduino\arduino-1.0.1\hardware\arduino\cores\arduino/keypad.h:36:25: error: utility/Key.h: No such file or directory
I downloaded the keypad example and in the Verify process this error appears…
This is the code:
#include <Key.h>
#include <Keypad.h>
const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
{‘1’,‘2’,‘3’},
{‘4’,‘5’,‘6’},
{‘7’,‘8’,‘9’},
{’*’,‘0’,’#’}
};
byte rowPins[ROWS] = {5, 4, 3, 2}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {8, 7, 6}; //connect to the column pinouts of the keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
void setup(){
Serial.begin(9600);
}
void loop(){
char key = keypad.getKey();
if (key){
Serial.println(key);
}
}
Can anyone help?
