 either `HIGH` or `LOW`. When set `HIGH` the pin will give 3.3V, when set to 
 `LOW` 0V.
 
+Note that there are two ways of specifying the digital pin: using the GPIO label (e.g. `P8_07`), or using the digital IO index (e.g. 0)

 To keep track of elapsed time we have a sample counter count. When the count reaches 
 a certain limit it switches state to either `HIGH` or `LOW` depending on its current 
 value. In this case the limit is `context->digitalSampleRate*interval` which
