New firmware release: version 1.2.0-dev

A project log for PD Buddy Sink

Smart power jack for USB Power Delivery

As requested, I just made a development release, 1.2.0-dev.  There are quite a few planned features not yet implemented, and as such I don't consider this release "stable" (that is, boards I sell won't ship with this firmware unless you explicitly ask for it).  What this release does provide is support for USB Power Delivery 3.0, bringing with it support for Programmable Power Supply APDOs (both making requests from them and pretty-printing them with get_source_cap).  Also in this release is basic support for voltage ranges, allowing a fallback to common fixed supply PDOs when the preferred voltage is unavailable.  The HV_Preferred flag does what it's supposed to, but the current is always constant when making requests from a range (no power or resistance modes yet).

So, if you're feeling adventurous, head over to the releases page, download the compiled binary for 1.2.0-dev, and flash it to your PD Buddy Sink!  As always, feedback is encouraged. 🙂

EDIT: added a direct link to the firmware binary

by the way, in combination with the anywatt, it will turn any charger/portable power source in a powerful and versatile bench top power supply.

thanks Clayton, really love the latest additions

You're welcome, I'm glad you like it!  I plan to release the stable 1.2.0 firmware soon, which will bring a few more nice features (perhaps most importantly, putting the Sink into the DFU bootloader by typing "boot" in the configuration interface so that future updates will be easier to install).  At this point, I mainly have a few documentation updates to do before I can call it done.

I somehow hadn't heard of the Anywatt, that's a really interesting device!  I might have to get one to play around with at some point.

the Satechi is not pd 3.0 compliant, even though on the website they mention 5-20v support. in the manual they only indicate 5,9, 15, 18, 20v... the rest don't work :-(. stuck with an expensive brick.....
