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
