# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased] ### Fixed - `cc1101-transmit` command: - configure transceiver after reading from stdin to avoid delay between configuration and transmission, if pipe is slow ## [2.5.0] - 2020-12-30 ### Added - added command `cc1101-transmit` to transmit via command-line interface - warn when selecting frequency below supported range ## [2.4.0] - 2020-12-13 ### Added - support chip version `0x04` ## [2.3.0] - 2020-12-11 ### Added - option `CC1101(lock_spi_device=True)` sets an advisory, exclusive, non-blocking `flock` on the SPI device file `/dev/spidev?.?` - method `.unlock_spi_device()` to release `flock` manually ## [2.2.0] - 2020-12-08 ### Added - select arbitrary device via `CC1101(spi_bus=?, spi_chip_select=?)` - added explanation to `PermissionError` on `SpiDev.open()` ## [2.1.0] - 2020-12-04 ### Added - method `.get_sync_word()` - method `.set_sync_word()` - method `.get_preamble_length_bytes()` - method `.set_preamble_length_bytes()` - preamble length & sync word in string representation ## [2.0.0] - 2020-12-03 ### Changed - `transmit()`: prepend length byte in variable packet length mode internally to avoid accidental incomplete transmissions and TX FIFO underflows ## [1.2.0] - 2020-12-02 ### Added - support for fixed packet length mode via new method `set_packet_length_mode(PacketLengthMode.FIXED)` - new enum `options.PacketLengthMode` - new method `get_packet_length_mode()` - method `get_packet_length_bytes()` is now public - new method `set_packet_length_bytes()` - added configured packet length to `CC1101`'s string representation (`≤n` indicates variable length mode, `=n` fixed length mode) ## [1.1.0] - 2020-12-01 ### Added - method `disable_checksum()` to disable automatic CRC sum appending in TX mode and checking in RX mode ## [1.0.0] - 2020-09-02 ### Added - `CC1101` class providing - context manager to open SPI port - `transmit()` for buffered transmission - context manager `asynchronous_transmission()` for manual signal generation - `get_configuration_register_values()` to read all configuration registers - OOK modulation - configurable symbol rate & sync mode - optional manchester encoding - disabled data whitening - automatic calibration [Unreleased]: https://github.com/fphammerle/python-cc1101/compare/v2.5.0...HEAD [2.5.0]: https://github.com/fphammerle/python-cc1101/compare/v2.4.0...v2.5.0 [2.4.0]: https://github.com/fphammerle/python-cc1101/compare/v2.3.0...v2.4.0 [2.3.0]: https://github.com/fphammerle/python-cc1101/compare/v2.2.0...v2.3.0 [2.2.0]: https://github.com/fphammerle/python-cc1101/compare/v2.1.0...v2.2.0 [2.1.0]: https://github.com/fphammerle/python-cc1101/compare/v2.0.0...v2.1.0 [2.0.0]: https://github.com/fphammerle/python-cc1101/compare/v1.2.0...v2.0.0 [1.2.0]: https://github.com/fphammerle/python-cc1101/compare/v1.1.0...v1.2.0 [1.1.0]: https://github.com/fphammerle/python-cc1101/compare/v1.0.0...v1.1.0 [1.0.0]: https://github.com/fphammerle/python-cc1101/releases/tag/v1.0.0
