* @brief Sample & upload data to Edge Impulse Studio.
* @details Select 1 or multiple sensors by un-commenting the defines and select
* a desired sample frequency. When this sketch runs, you can see raw sample
* values outputted over the serial line. Now connect to the studio using the
* `edge-impulse-data-forwarder` and start capturing data
// #define SAMPLE_ACCELEROMETER
// #define SAMPLE_GYROSCOPE
// #define SAMPLE_ORIENTATION
#define SAMPLE_ENVIRONMENTAL
// #define SAMPLE_ROTATION_VECTOR
* Configure the sample frequency. This is the frequency used to send the data
* to the studio regardless of the frequency used to sample the data from the
* sensor. This differs per sensors, and can be modified in the API of the sensor
