*
|
|
* Demonstrates using the SPA06_003 sensor with SPI interface.
|
|
* This example shows both hardware and software SPI configurations.
|
|
*
|
|
* The begin() function automatically configures the sensor for:
|
|
* - Highest precision (128x oversampling)
|
|
* - Highest sample rate (200 Hz)
|
|
* - Continuous measurement mode
|
|
* - Interrupt-based data ready detection
|
|
*
|
|
* Designed specifically to work with the Adafruit SPA06_003 Breakout
|
|
* ----> https://www.adafruit.com/products/xxxx
|
|
*
|
|
* These sensors support both I2C and SPI interfaces.
|
|
* For SPI connections:
|
|
* - CS -> pin 10 (or any digital pin)
|
|
* - MOSI -> pin 11
|
|
* - MISO -> pin 12
|
|
* - SCK -> pin 13
