/* Author: Allan K Liu Original: Athanassios Mavrogeorgiadis Changes: - Optimization for Low Power Consumption Operations - GD0 as external interrupt, to bring MCU from deep sleep mode. - GPIO setup - Clock setup - Event driven design - ALOHA transceiver for channel access with RTS/CTS/ACK - S-MAC - Cloned high level designs from SimpliciTI. - New CircularBuffer from mbed 5 Status: - CC1101 SPI access to regsiters from PARTNUM/VERSION to RCCTRL0 not stable - PARTNUM ranges from 0x00/0xFF - VERSION ranges from 0x0F/0x1F/0x4F */ #include "mbed.h" #include "CC1101.h" #include "RingBuffer.h" #if defined(TARGET_NUCLEO_F103RB) || defined(TARGET_LPC824) // RDmiso is actually the MISO, // SPI only works after MISO turns into low from Hi-Z state of CC1101 // Therefore we need a dedicated input to detect.
