Grazie per la risposta astrobeed
Potrebbe dunque essere così il collegamento?
Arduino | lcd
12 ----> Rs
11 ----> E1
10 ----> E2
5 ----> DB4
4 ----> DB5
3 ----> DB6
2 ----> DB7
Lo sketch doppio?
#include <LiquidCrystal.h>
// initialize the library with //
// the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup()
{
// set up the LCD's number of rows and columns: lcd.begin(40, 2);
// Print a message to the LCD.
lcd.print("hello, world!"); }
} void loop()
{ // set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}
// initialize the library with //
// the numbers of the interface pins
LiquidCrystal lcd(12, 10, 5, 4, 3, 2);
void setup()
{
// set up the LCD's number of rows and columns: lcd.begin(40, 2);
// Print a message to the LCD.
lcd.print("hello, world!"); }
} void loop()
{ // set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}
Perdonami... un pò di pazienza
