| * APPLICATION SPECIFIC NOTES (READ THIS!!!): | ||
| * - This code configures an Arduino to interface with an HDC1080 from Texas | ||
| * Instruments. | ||
| * - Configure Arduino (I2C, UART, etc) | ||
| * - Perform initial verification and configuration of the HDC1080 | ||
| * - The HDC1080 is an I2C-only device | ||
| * - read status/info from sensor | ||
| * - Write formatted information to serial port | ||
| * - I2C specific note: This example uses the I2C interface via the I2C lib, not | ||
| * the 'Wire' lib included with the Arduino IDE. | ||
| * | ||
| * Circuit: | ||
| * Arduino Uno Arduino Mega --> SEN-37001: HDC1080 Breakout | ||
| * SDA: SDA SDA --> SDA | ||
| * SCL: SCL SCL --> SCL | ||
| * GND: GND '' --> GND | ||
| * 5V: 5V '' --> VDD | ||
| * (note: VDD should match voltage of IO, and can be between 3.3 and 5V) | ||
