    PD Buddy Sink Firmware v1.2.2

    clara пре 5 година 0 комита на 1.2 почев од овог издања

    A patch release which adds a new LED blink code for when only default USB power is available. The blink code for this is 1 7/8 s on, 1/8 s off.

  • Стабилно v1.2.0 8c00b79c26

    PD Buddy Sink Firmware v1.2.0

    clara пре 6 година 8 комита на master почев од овог издања

    A new minor release, bringing support for Power Delivery 3.0 communication, programmable power supplies, requests from voltage ranges, new methods of specifying the required power level, and jumping to the STM32 DFU bootloader.

    Features

    • Requests can be made from programmable power supplies, allowing voltages to be requested at 20 mV increments from a wide range (up to 3-21 V).
    • Configuring a voltage range with the new set_vrange command provides a fallback if the preferred voltage is unavailable.
    • Higher or lower voltages from a range may be preferred; this can be set with toggle_hv_preferred.
    • The amount of current the device requests can be set as a power (set_p) or a resistance (set_r), as well as a current. These values are taken as constant over the configured voltage range.
    • Firmware upgrades are easily possible via Setup mode. Running the new boot command causes the firmware to run the microcontroller’s built-in DfuSe bootloader.

    For this release, the firmware was reorganized as a library for USB Power Delivery and an application using that library. The library is released under the Apache License, Version 2.0, and the application is still released under the GNU General Public License, Version 3.0. Both parts of the firmware are still kept in this repository, but this may change at some point.

    PD Buddy Sink Firmware v1.2.0-dev

    clara пре 6 година 32 комита на master почев од овог издања

    A development release for version 1.2.0.

    Features

    • Firmware can now make requests from USB PD 3.0 programmable power supplies
    • Basic support for voltage ranges was added (constant current only, HV_Preferred flag works)
     
  • Стабилно v1.1.0 fa65664d16

    PD Buddy Sink Firmware v1.1.0

    clara пре 6 година 126 комита на master почев од овог издања

    A new minor release, bringing the ability to do Power Delivery communications in Sink mode. Two new commands were introduced to support this:

    • output: Enable or disable the power output, or read its current status.
    • get_source_cap: Print the advertised capabilities of the Power Delivery source.

    To match the old behavior, the power output is disabled by default in Sink mode, and remains disabled unless explicitly enabled by the user. If the output is enabled, the configured power is negotiated immediately and made available on the output connector. Negotiation is then done every time new configuration is written to flash, so that new power can be acquired quickly and easily.

    A minor bugfix release which improves the handling of invalid voltages and currents in the configuration interface.

     
  • Стабилно v1.0.0 d6bd465077

    PD Buddy Sink Firmware v1.0.0

    clara пре 6 година 150 комита на master почев од овог издања

    Initial firmware release for the PD Buddy Sink.

    Features

    • Two boot modes, Setup and Sink, selected by the Setup button’s state at startup.
    • Sink mode implements a simple USB Power Delivery sink, aiming for full compliance with the USB Power Delivery Specification, Revision 2.0, Version 1.3.
    • Requests the configured voltage and current if available, or a safe, low power request otherwise.
    • Provides power on the output connector only when an explicit contract is in place for the configured voltage and current.
    • Optional GiveBack support allows power supplies to temporarily remove power from the PD Buddy Sink if necessary.
    • Setup mode implements a USB CDC-ACM command-line interface allowing configuration to be loaded from and stored in flash.
