 This is a manual test application for the HDC1000 driver.
 
 # Usage
-This test application will initialize the HDC1000 sensor with the following parameters:
- - Temperature and humidity are acquired in sequence
- - Temperature measurement resolution 14 bit
- - Humidity measurement resolution 14 bit
+This test application will initialize the HDC1000 sensor with the configuration
+as specified in the default `hdc1000_params.h` file (i.e. 14-bit resolution).
 
-After initialization, the sensor reads the temperature and humidity values every 1s
-and prints them to STDOUT.
+If you want to use this test application with different parameters, you can
+simply override the default settings on the command line like this:
+```
+CFLAGS="-DHDC1000_PARAM_I2C=I2C_DEV\(1\) -DHDC1000_PARAM_RES=HDC1000_11BIT" make
+```
+
+After initialization, the sensor reads the temperature and humidity values every
+second and prints them to STDOUT.
