Hard Fault when using pushImage

[mesbahuddin]

Hello...

i was trying to us your lgfx_slim but i faced followinhg issue :

teh code crashes (harrd fault) when ever i execute pushImage !!

#define RGB_TEST_HEIGHT 6
#define RGB_TEST_WIDTH 4

// array size is 48
static const uint16_t rgb_test[] = {
0xf800, 0xf800, 0xf800, 0xf800,
0xf800, 0xf800, 0xf800, 0xf800,
0x07e0, 0x07e0, 0x07e0, 0x07e0,
0x07e0, 0x07e0, 0x07e0, 0x07e0,
0x001f, 0x001f, 0x001f, 0x001f,
0x001f, 0x001f, 0x001f, 0x001f
};

int main(void) {

auto canvas = lgfx::LGFX_Sprite();
canvas.createSprite(RGB_TEST_WIDTH, RGB_TEST_HEIGHT);
canvas.setColorDepth(lgfx::rgb565_nonswapped);

canvas.pushImage(0, 0, RGB_TEST_WIDTH, RGB_TEST_HEIGHT, (uint16_t*)rgb_test);

/* Infinite loop */
while (1) {
	HAL_Delay(500);
}

}
