Install the library

To download, click the Download Zip button. In the Arduino IDE go to Sketch -> Include Library -> Add .ZIP Library.

Or, you may install this library with the Arduino Library Manager.

For details on installing libraries, see Arduino's guide at: https://www.arduino.cc/en/Guide/Libraries#toc3

Use

Include the library and declare a sensor:

#include <HoneywellTruStabilitySPI.h>
// construct a +/- 15 PSI sensor using the default SPI slave select pin (SS)
TruStabilityPressureSensor sensor( SS, -15.0, 15.0 );

Initialize the sensor in void setup() :

SPI.begin(); // start SPI communication
sensor.begin(); // run sensor initialization

Read values in void loop() :

// the sensor returns 0 if new data is ready
if( sensor.readSensor() == 0 ) {
  float t = sensor.temperature();
  float p = sensor.pressure();
}
