C++ (Cpp) send_rgb Examples

Example #1

File: main.c Project: tcauchois/Syzycubes

void banner()
{
  //console banner
  printf_P(PSTR("Syzygryd Memorial Cube Firmware.  Hello!\n"));

  //give the user a visual indication of battery health...
  uint8_t bat = get_battery_percent();
  if(bat == 0) {
    lowbat();
  } else {
    // Show the battery level
    send_rgb(100 - bat, bat, 0);
    _delay_ms(1000);
    send_rgb(0, 0, 0);
  }
}

Example #2

File: main.c Project: sunkaizhu/zephyr

void main(void)

	int ret;
	int idx = 0;

Example #3

File: console.c Project: tcauchois/Syzycubes

char ledCmdRgb(char *arg)
{
  unsigned long r,g,b;
  r = strtoul(arg, &arg, 16);
  g = strtoul(arg, &arg, 16);
  b = strtoul(arg, &arg, 16);

  send_rgb((uint16_t)r, (uint16_t)g, (uint16_t)b);
  return 0;
}

Example #4

File: main.c Project: tcauchois/Syzycubes

//blink LEDs and turn off (in case of low battery)
void lowbat()
{
  send_rgb(100, 0, 0);
  _delay_ms(200);
  send_rgb(0, 0, 0);
  _delay_ms(200);
  send_rgb(100, 0, 0);
  _delay_ms(200);
  send_rgb(0, 0, 0);
  _delay_ms(200);
  send_rgb(100, 0, 0);
  _delay_ms(200);
  send_rgb(0, 0, 0);
  shutdown(1);
}

Example #5

File: main.c Project: tcauchois/Syzycubes

void shutdown(int forever)
{
  // Turn off the LEDs
  send_rgb(0,0,0);

  // Reset the ADXL threshold level
  adxl345_write(THRESH_ACT, 50); // Threshold to detect activity

  // If we don't want to turn back on turn off the accelerometer
  if(forever)
    adxl345_write(POWER_CTL, 0);

  // Loop until we die
  while(1)
  {
    // Read the ADXL interrupts to clear out PWR_EN_ADXL
    adxl345_read(INT_SOURCE);

    // Lower the power latch (PWR_EN_CPU)
    PORTC &= ~(_BV(PORTC4));

    _delay_ms(5000);
