driver library for Ti CC1100 / CC1101.
Contains Lib for Arduino and Raspberry Pi.
Note: Raspi need wiringPi
a compatible and tested library for TI MSP430 is provided by abhra0897.

check cc1101_arduino.h and/or cc1101_raspi.h for Pin description
CC1101 Vdd = 3.3V CC1101 max. digital voltage level = 3.3V (not 5V tolerant)
CC1101<->Arduino
Vdd - 3.3V
SI - MOSI (11)
SO - MISO (12)
CS - SS (10)
SCLK - SCK (13)
GDO2 - GPIO ( 3)
GDO0 - not used in this demo
GND - GND
CC1101<->Raspi
Vdd - 3.3V (P1-01)
SI - MOSI (P1-19)
SO - MISO (P1-21)
CS - SS (P1-24)
SCLK - SCK (P1-23)
GDO2 - GPIO (P1-22)
GDO0 - not used in this demo
GND - P1-25
-> pkt_len [1byte] | rx_addr [1byte] | tx_addr [1byte] | payload data [1..60bytes]
pkt_len = count of bytes which shall transfered over air (rx_addr + tx_addr + payload data)
rx_addr = address of device, which shall receive the message (0x00 = broadcast to all devices)
tx_addr = transmitter or my address. the receiver should know who has sent a message.
payload = 1 to 60 bytes payload data.
TX Bytes example:
-> 0x06 0x03 0x01 0x00 0x01 0x02 0x03
use uint8_t CC1100::begin(volatile uint8_t &My_addr) always as first configuration step. For Arduino devices, this function returns the device address, which was already stored in the Arduino EEPROM.
you should set a unique device address for the transmitter and a unique device address for the receiver. This can be done with void CC1100::set_myaddr(uint8_t addr).
i.E. -> TX = 0x01 ; RX = 0x03
the following modulation modes can be set by void CC1100::set_mode(uint8_t mode). Transmitter and receiver must have the same Mode setting.
1 = GFSK_1_2_kb
2 = GFSK_38_4_kb
3 = GFSK_100_kb
4 = MSK_250_kb
5 = MSK_500_kb
6 = OOK_4_8_kb
you can set a frequency operation band by void CC1100::set_ISM(uint8_t ism_freq) to make it compatible with your hardware.
1 = 315
2 = 433
3 = 868
4 = 915
CC1101 RF settings must be stored in the Arduino EEPROM to have maximum flexibility with different mode settings and reduced memory usage. Follow the following steps, how to store the compiled EEPROM file (*.eep) to your Arduino EEPROM. From my experience, you have to repeat this step only, if you have changed the Arduino Version, because the gcc compiler defines the location of the eeprom settings.
./eeprom_create.py <input *.eep file>
w
to the input field and press the sent buttonr
to verify that eeprom is written.be sure first, that you have already wiringPi installed on your Raspberry Pi hardware.
