Implementation examples, unit tests, and simulations for quadra.
There's currently a single implementation example, written for the
STM32F4 Discovery
board. See example/README.md.
A suite of unit tests for the decoder and encoder can be found in the
unit_tests directory. They depend on:
Run the tests using these commands:
make check
make py-check
There are simulations of the decoder, demodulator, and PLL under the sim
directory. Run them with the commands:
make run-sim-decoder
make run-sim-demodulator
make run-sim-pll
You can view simulation traces using GTKWave, for which project files are provided.
