-This program is an example of the startup sequence for HackRF (Jellybean with
-Lemondrop attached).
-LED1, LED2, and LED3 are blinking at exactly a frequency of 1Hz upon success.
-
-Required Lemondrop -> Jellybean connections:
-
-SCL: Lemondrop P7 pin 3 -> Jellybean P6 pin 3
-SDA: Lemondrop P7 pin 5 -> Jellybean P6 pin 5
-SDA: Lemondrop P7 pin 6 -> Jellybean P6 pin 6
-VCC: Lemondrop P4 pin 2, 4, or 6 -> Jellybean P17 pin 2, 4, or 6
-1V8: Lemondrop P11 pin 2, 4, or 6 -> Jellybean P16 pin 2, 4, or 6
-GND: Lemondrop P5 -> Jellybean P13
