I tried the Crystal Ball project from the Starter Kit book, and I get this error:
26:14: error: statement cannot resolve address of overloaded function
I don't have line numbers in the IDE but it seems to apply to the
"reply=random(8 )" line just at the beginning of the loop function.
A previous forum topic about the same error showed that the error was the line before the line that the poster's debugger flagged, though.
I quadruple-checked the lines involved, both from what I know (not much) about C and from what was printed in the book, and I still can't find the error...
#include <LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
const int switchPin=10;
int switchState=0;
int prevSwitchState=0;
int reply;
void setup() {
lcd.begin(16,2);
pinMode(switchPin, INPUT);
lcd.print("Ask the");
lcd.setCursor(0,1);
lcd.print("Crystal Ball");
}
void loop() {
switchState = digitalRead(switchPin);
if (switchState != prevSwitchState) {
if (switchState == LOW) {
reply=random(8);
lcd.clear;
lcd.setCursor(0,0);
lcd.print("The ball says:");
lcd.setCursor(0,1);
switch(reply) {
case 0:
lcd.print("Yes");
break;
case 1:
lcd.print("Most Lilely");
break;
case 2:
lcd.print("Certainly");
break;
case 3:
lcd.print("Outlook good");
break;
case 4:
lcd.print("Unsure");
break;
case 5:
lcd.print("Ask again");
break;
case 6:
lcd.print("Doubtful");
break;
case 7:
lcd.print("No");
break;
}
}
}
prevSwitchState=switchState;
}
