8 A simple example of getting debug info from the nRF24L01 transceiver.
9
10 This example was written to demonstrate alternative methods to get debugging data.
11 1. radio.encodeRadioDetails() will provide a data dump of all the nRF24L01's registers.
12 2. radio.sprintfPrettyDetails() will behave similarly to printPrettyDetails(), but it
13 outputs to a char buffer that can be printed to any Serial (or other output) stream.
14
15 Additionally, this example will show all default configuration values.

26 For this example, we'll be using a data buffer containing
27 radio details encoded with RF24::encodeRadioDetails().
28 It is meant to be decoded by an external program.

31 will take a space-delimited string of hexadecimal characters and
