CircuitPython library for RFM69 packet radio.
Project description
Introduction
CircuitPython RFM69 packet radio module. This supports basic RadioHead-compatible sending and receiving of packets with RFM69 series radios (433/915Mhz).
Dependencies
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Usage Example
See examples/rfm69_simpletest.py for a simple demo of the usage. Note: the default baudrate for the SPI is 5000000 (5MHz). The maximum setting is 10Mhz but transmission errors have been observed expecially when using breakout boards. For breakout boards or other configurations where the boards are separated, it may be necessary to reduce the baudrate for reliable data transmission. The baud rate may be specified as an keyword parameter when initializing the board. To set it to 1000000 use :
# Initialze RFM radio
rfm9x = adafruit_rfm9x.RFM9x(spi, CS, RESET, RADIO_FREQ_MHZ,baudrate=1000000)Contributing

Building locally
To build this library locally you’ll need to install the circuitpython-build-tools package.
python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-toolsOnce installed, make sure you are in the virtual environment:
source .env/bin/activateThen run the build:
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-rfm69 --library_location .Sphinx documentation
Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):
python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-themeNow, once you have the virtual environment activated:
cd docs
sphinx-build -E -W -b html . _build/htmlThis will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
