This program activates the MAX2837 transceiver to transmit an unmodulated carrier. Required Lemondrop -> Jellybean connections: SCK: Lemondrop P3 pin 2 -> Jellybean P9 2 CS_XCVR: Lemondrop P3 pin 3 -> Jellybean P9 3 MOSI: Lemondrop P3 pin 4 -> Jellybean P9 4 CS_AD: Lemondrop P3 pin 5 -> Jellybean P9 5 MISO: Lemondrop P3 pin 6 -> Jellybean P9 6 ENABLE: Lemondrop P6 pin 12 -> Jellybean P7 pin 12 RXENABLE: Lemondrop P6 pin 13 -> Jellybean P7 pin 13 TXENABLE: Lemondrop P6 pin 15 -> Jellybean P7 pin 15 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 GND: Lemondrop P5 -> Jellybean P13 For now we are running everything at 3.3 V, but in the future we may also require: 1V8: Lemondrop P11 pin 2, 4, or 6 -> Jellybean P16 pin 2, 4, or 6
