About

This is a manual test application for the CCS811 driver. It shows how the sensor can be used for periodic polling as well as with interrupts.

Usage

The test application demonstrates the use of the CCS811. It uses the default configuration parameters, that is, the measurement mode CCS811_MODE_1S with one measurement per second.

The application can use both approaches to wait for new data:

  1. using the data-ready interrupt (CCS811_INT_DATA_READY):

    #define USE_CSS811_DATA_READY_INT  (1)

  2. using the data-ready status function (ccs811_data_ready)

    #define USE_CSS811_DATA_READY_INT  (0)

If data-ready interrupts are used, the default configuration parameter for the interrupt pin can be overriden by CCS811_PARAM_INT_PIN before ccs811_params.h is included.

#define CCS811_PARAM_INT_PIN     (GPIO_PIN(0, 12))
