Change log

  • When getopt() is active (CONFIG_SHELL_GETOPT=y), the Zephyr shell is not parsing command handler to print help message. It must be done explicitly inside the command implementation.

  • Update GPIO to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree.

  • Use Board extensions to extended Zephyr upstream board configurations. In some situations, certain hardware description or choices can not be added in the upstream Zephyr repository, but they can be in a downstream project, where custom bindings or driver classes can also be created. This feature may also be useful in development phases, when the board skeleton lives upstream, but other features are developed in a downstream module. Thus the extensions spinned around in different shields or snippets were centraliced as board extensions, e.g. the special Raspberry Pi Pico R3 edge connector binding.

  • Remove special board extensions for Nucleo F303RE/F401RE, NXP MIMXRT1010-EVK, and RPi Pico from the Grove Interconnect Shield.

  • Convert all RP2040 based boards to the new Clock Controller support.

  • Adds the new DTS binding pwm-buzzers, which can be used in the same way as the Zephyr upstream binding pwm-leds; but here for simple buzzers, each used by a dedicated PWM channel to output simple digital sounds. A simple buzzer sample is now also part of Bridle. This can be used for simple music playback via PWM.

  • Adds the new DTS binding pwm-servos to combine several PWM channels in one node and make different numbers of servomotors known via alias entries. As long as there is no stable servo motor or motion API in Zephyr or Bridle, this binding will remain in flux and will not be finished.

  • Add the new PWM Servomotor Preset Snippet (pwm-servo) for quite board specific preperations of the standard Zephyr Servomotor sample. Add support for the following boards:

    • Cytron Maker Pi RP2040

  • Add more boards to the USB Console Snippet (usb-console):

    • Cytron Maker Nano RP2040

    • Cytron Maker Pi RP2040

    • NXP MIMXRT1010-EVK

    • NXP MIMXRT1060-EVK

    • Raspberry Pi Pico (W)

    • Raspberry Pi Pico LCD Shields:

      • Pico LCD 1.14 shield by Waveshare

      • Pico LCD 2 shield by Waveshare

    • NXP MIMXRT1010-EVK

The following sections provide detailed lists of changes by component.

Build Infrastructure

Take over the new build principles from Zephyr:

  • Use the new upstream MIPI DBI API for all ILI9xxx based displays.

  • Take over upstream ci/check_compliance.py from Zephyr, adapt with all the needs for Bridle and extend support for external module roots as defined by Zephyr module settings (MODULE_EXT_ROOT).

  • Use new ci/check_compliance.py on GitHub workflow QA Compliance Check to do following with each PR:

    • Checks various nits in added/modified files, not coverd by other checks, e.g. checkpatch.pl and pylint.

    • Checks if Emails of author and signed-off messages are consistent.

    • Checks for conflict markers or whitespace errors.

    • Run Git, Python and YAML linting on the commits and find issues with style and syntax.

    • Check that MAINTAINERS file parses correctly.

    • Check that all modules have a MAINTAINERS entry.

    • Checks introducing any unwanted properties in Devicetree Bindings.

    • Checks introducing any new warnings/errors with Kconfig when no modules are available.

    • Checks introducing any new warnings/errors with Kconfig, the basic Kconfig test, which is checking only for undefined references.

    • Check for blocks of code or config that should be kept sorted.

    • Check that the diff contains no binary files that are not tollerated.

    • Check that any added image is limited in allowed size.

  • Provide a nix flake for reproducible development and build environments. The new nix flake definition, which provides as output a devshell, is now setup a development environment containing all necessary tools and libraries to work with Bridle. Really all dependencies, i.e. both system packages on the host and all necessary Python packages.

Documentation

  1. All scattered links to external resources and internal references to sections in the various docsets (e.g. Bridle or Zephyr) were moved to a central location in the files links.txt and shortcuts.txt and thus centralized.

  2. Clarification that the Zephyr SDK will indeed be used and is the preferred default toolchain. All other references to the GNU toolchains by ARM Ltd. are entirely optional and may or may not be used.

  3. Update all output messages in documentation to be in sync with the upcoming Bridle version v3.6.1, based on Zephyr v3.6 (samples and tests).
