This program activates the MAX2837 transceiver to transmit an unmodulated
carrier. It also configures the RFFC5071 to downconvert the carrier to a lower
frequency.
Required Lemondrop -> Jellybean connections:
SCK: Lemondrop P3 pin 2 -> Jellybean P9 2
MOSI: Lemondrop P3 pin 4 -> Jellybean P9 4
MISO: Lemondrop P3 pin 6 -> Jellybean P9 6
SSEL: Lemondrop P3 pin 3 -> Jellybean P9 3
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
Required Lollipop -> Jellybean connections:
GND: Lollipop P8 pin 1, 3, or 5 -> Jellybean P17 pin 1, 3, or 5
VCC: Lollipop P8 pin 2, 4, or 6 -> Jellybean P17 pin 2, 4, or 6
ENX: Lollipop P4 pin 5 -> Jellybean P5 pin 2
SCLK: Lollipop P4 pin 3 -> Jellybean P5 pin 4
SDATA: Lollipop P4 pin 1 -> Jellybean P5 pin 6
Also RF connectors, and you're on your own to get the RF switches configured
properly.
