# AMS CCS811 device driver test application

## About

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

**Please note:** The interrupt pin has to be defined for this test application.

## Usage

The test application demonstrates the use of the CCS811 and pseudomodule
```ccs811_full``` using

- data-ready interrupt ```CCS811_INT_DATA_READY``` and
- default configuration parameters, that is, the measurement mode
  ```CCS811_MODE_1S``` with one measurement per second.

The default configuration parameter for the interrupt pin has to be
overridden according to the hardware configuration by defining
```CCS811_PARAM_INT_PIN``` before ```ccs811_params.h``` is included, e.g.,

    #define CCS811_PARAM_INT_PIN     (GPIO_PIN(0, 7))

or via the `CFLAGS` variable in the make command.

    CFLAGS="-DCCS811_PARAM_INT_PIN=\(GPIO_PIN\(0,7\)\)" make -C tests/driver_ccs811 BOARD=...
