kenney example

[gamer]

Hi,

I am not being able to run the kenney example. It runs only for 3 seconds for me. Is there something to be done with the asset converter?

It should run in a loop indefinitely.

Does the "selftest" pass?

[gamer]

Yes. It runs in a loop indefinitely. The loop contents are for 2-3 seconds.
Is that the expected result?

The selftest passes.

The kenney loop is 13s long... it should look like this.
One quick thing to check is power. Does a different USB port/cable make a difference? It could be that voltage droop is causing the Arduino to reboot.

I tried changing the cable. No change.

I tried debugging by commenting out some code.

static void draw(int t)
{
int y = 1648 - t;
// GD.finish(); long t0 = micros();

// GD.ClearColorRGB(0xd0f4f7); GD.Clear();
GD.cmd_gradient(0, 0, 0xa0a4f7,
0, 272, 0xd0f4f7);

GD.RestoreContext();
GD.BlendFunc(ONE, ONE_MINUS_SRC_ALPHA);
GD.Begin(BITMAPS);
GD.BitmapHandle(TILES_HANDLE);
const PROGMEM prog_uchar *src = layer1_map + (y >> 5) * 15;
byte yo = y & 31;
for (byte j = 0; j < 10; j++)
for (byte i = 0; i < 15; i++) {
byte t = pgm_read_byte_near(src++);
if (t != 0) {
GD.Cell(t - 1);
GD.Vertex2f(16 * 32 * i, 16 * ((32 * j) - yo));
}
}

GD.swap();
}

With this draw function, the code is in an infinite 2 second loop. That's exactly the background of the output I'm getting with the full code.

Anything to do with this piece of code?

Aah..it's not that.

In the website, it's
void loop()
{
for (int t = 0; t < 720; t++) {
draw(t);
}
}

In the downloaded code, it was t<100.
Solved. Thanks.
