Tiny & quick-written test routine to show the functionality of the build-in g-sensor.
Zero-tilt: blue & green LED is on. (in centered RGB-LED)
Tilting only left & right changes from center blue-green to left yellow LED (left tilt) or right yellow LED (right tilt). The centered green LED stays on to signalize, that there's no tilting back & forth.
Tilting only back or forth changes from center blue-green to center blue-red. The blue LED stays on.
Tilting in one of the for corners changes the center RGB-LED from blue-green to red and lights up one of the two yellow LED left or right from the center RGB-LED depending on the corner you are tilting in.
yellow(l)/red - blue/red - yellow(r)/red
yellow(l)/green - blue/green - yellow(r)/green
yellow(l)/red - blue/red - yellow(r)/red
Using the AVR Software Framework in the AVRstudio 5, all you'll need is:
int main(void)
{
// Initialize
sensor_platform_init();
// Define
sensor_t accel;
sensor_data_t accel_data; sensor_attach(&accel,SENSOR_TYPE_ACCELEROMETER,0,0);
accel_data.scaled = true; // acceleration in milli-G
int32_t app_x_value, app_y_value, app_z_value; // 3 varia-bles
int16_t inner = 150, outer = 140; // inner & outer boundary
while(1)
{
sensor_get_acceleration(&accel,&accel_data);
app_x_value = accel_data.axis.x;
app_y_value = accel_data.axis.y;
app_z_value = accel_data.axis.z;
if (app_x_value [U+003C] -outer) LED_On(LED_RGB0_RED);
if (app_x_value [U+003E] outer) LED_On(LED_RGB0_RED);
if (app_x_value [U+003C] inner) LED_On(LED_RGB0_GREEN);
if (app_x_value [U+003C] -inner) LED_Off(LED_RGB0_GREEN); if (app_y_value [U+003C] -outer) LED_On(LED0);
if (app_y_value [U+003E] outer) LED_On(LED1);
if (app_y_value [U+003C] inner) LED_On(LED_RGB0_BLUE);
if (app_y_value [U+003C] -inner) LED_Off(LED_RGB0_BLUE); delay_ms(500);
LED_Off(LED0_GPIO);
LED_Off(LED1_GPIO);
LED_Off(LED_RGB0_RED);
LED_Off(LED_RGB0_GREEN);
LED_Off(LED_RGB0_BLUE);
}
}
Since you can't use the less-than sign or the greater-than sign (looking like angle brackets) in youtube descriptions, I used instead the Unicode codes:
U+003E = 'GREATER-THAN SIGN'
U+003C = 'LESS-THAN SIGN'
less
