Python Library to Transmit RF Signals via CC1101 Transceivers

Setup

$ pip3 install --user --upgrade cc1101

On Raspbian / Raspberry Pi OS, dependencies can optionally be installed via:

$ sudo apt-get install --no-install-recommends python3-spidev

Wiring Raspberry Pi

Directly connect the following pins:

C1101 Raspberry Pi
VDD 3.3V (Pin 1 or 17)
SI MOSI (Pin 19)
SO MISO (Pin 21)
CSn CE0 (Pin 24)
SCLK SCLK (Pin 23)
GND Ground

No resistors required. GDO0 & GDO2 are currently unused.

Raspberry Pi GPIO docs: https://www.raspberrypi.org/documentation/usage/gpio/

Usage

See examples.

import cc1101

with cc1101.CC1101() as transceiver:
    transceiver.set_base_frequency_hertz(433.92e6)
    print(transceiver)
    transceiver.transmit(b"\x01\xff\x00 message")

In case a PermissionError gets raised, check the permissions of /dev/spidev*. You'll probably need sudo usermod -a -G spi $USER, followed by a re-login.
