Program Gamebuino with load_game

[jackB]

Why it doesn' t work ?

Code: Select all

#define load_game (*((void(*)(const char* filename))(0x7ffc/2)))

void setup() {
  Serial.begin(9600);
  Serial.println("Send a char to start...");
  char name[]="BLINK";
}

void loop() {
  if (Serial.available()) {
    Serial.read();
    load_game(name);
  }
}

Probably because you don't have a program named BLINK.HEX on your micro SD card?

When i write this it works..

Code: Select all

#define load_game (*((void(*)(const char* filename))(0x7ffc/2)))

void setup() {
  Serial.begin(9600);
  Serial.println("Send a char to start...");
}

void loop() {
  if (Serial.available()) {
    Serial.read();
    load_game("BLINK");
  }
}

But when i write this it doesn' t work

Code: Select all

#define load_game (*((void(*)(const char* filename))(0x7ffc/2)))

void setup() {
  Serial.begin(9600);
  Serial.println("Send a char to start...");
}
char name[]="BLINK";
void loop() {
  if (Serial.available()) {
    Serial.read();
    load_game(name);
  }
}

Why?

do you have test String name = "BLINK"; ?

Are you sure you're using the latest version of the Arduino IDE and compiler? You're not using a compiler that's placing the global char[] in PROGMEM by any chance?
