There is no recording of this meeting. The next recorded meeting on Discord will occur on 6 January 2020. + + +**Thank you all for your participation in and amazing contributions to the CircuitPython project in 2019. Code + Community = CircuitPython. We can write the code, but without your involvement, we can’t truly make it CircuitPython. The past year saw many new contributors to both the core and the libraries, as well as the continued contributions of those already involved. We had a number of new releases up to 5.0.0-beta.2, and passed 200 CircuitPython libraries. We now have nearly 100 CircuitPython supported boards available on circuitpython.org/downloads, many of which have been submitted by community members. That this project has continued to grow at such a rate is a testament to the importance of the community being a part of it. We deeply appreciate everything you do and we look forward to another fantastic year of Code + Community!** + + +Join here for the chat all week: http://adafru.it/discord + + +The CircuitPython Weekly happens normally at 2pm ET/11am PT on Mondays.

Thank you so much! +* @krayola for all the work going into the LED Animations library and Pixelbuf, for finding sparkly dark purple 3D printing filament, and for making our xmas tree an absolutely amazing LED display. +* Adafruit Learn Dev for always being quick with resolutions when issues come up - I’m rarely down for more than a short time when something goes awry in the Learn system, thanks! +* @MakerMelissa, @sommersoft, @siddacious, @dherrada for the excellent discussion regarding implementing some features into the GitHub Actions migration. +* Group hug to the community and Adafruit for another amazing year.

Yay!! +* Spent most of last week doing “secret” adafruit things, will probably materialize before EOY ‘19 +* Updated nina-fw to v1.6.0, built on latest esp-idf version. Large security patch along with smaller wifi bug fixes. +* Spent time getting some Jupyter/MCP221+FT232H demos up and running, that’s what I’ll be hacking on this week. + + +@CGrover +* Made progress on the PyGamer-based Vent Monitor. Just a few more tweaks before starting on the enclosure and mount. CircuitPython is fast enough to work nicely with the 8x8 thermal sensor array wing to produce a useful image and histogram. Teaming Displayio with PyBadger made it fairly easy to get the project working. +Finished all but one PCB build. Hoping to get to that final one between holiday meals and movies. +* Refining the PyPanel concept code. Used it to get a quick prototype of the Vent Monitor going. The PyPanel concept is very useful for project prototyping and proof-of-concept. Need to further evaluate its impact on performance for memory-constrained or time-critical projects. + +@danh +* Writing BLE bonding code. +* Debugging a number of issues with the UF2 bootloader, including fuse repair problems and spurious writes to internal flash. + + +@jepler +The last few weeks: +* Progress on SAMD DMA hang (PRd a possible fix in a submodule) +* Fixed allocation errors in jeplayer with mp3file enhancements +* Still getting scratchiness in specific MP3s +* Continuing with jeplayer development & the core improvements it is driving +* Light pipe digit display project: simple GPIO-based board design works. Had good success with my first stencil & hot air board soldering! +* Keyboard project: putting off bluetooth for now, going with itsy bitsy m4 -- tenkeyless easiest matrix needs 23 I/Os, will make a smaller matrix when it’s time for bluetooth + + +@jerryn +* Making progress on “reliable datagram” mode for the RFM9x + * I have a working (mostly) version that still needs lots of testing + * Encouraging start + + +@kattni +* Last two weeks: + * Complicated Fritzing objects - PyPortals Pynt and Titano + * Easier Fritzing object - Feather eInk Friend + * Updated eInk guide to include Feather Friend + * Added Pynt to the PyPortal guide with pinouts images etc + * Created, wrote and published the PyPortal Titano guide + * Tested and retested and tested again the Circuit Playground library update on Express with the stack size update etc. + * Started updating the CircuitPython Made Easy on Circuit Playground Express and Bluefruit guide to use the new imports for the Circuit Playground library so the guide will work with Bluefruit as well. + * This is a major overhaul as there are a lot of Mu screenshots and in-line code explanation. + * So far: Red LED and slide switch are updated + * Mostly off for the holiday +* Today and next week: + * Python on Hardware newsletter + * Plan to be back to the usual on 2 January 2019 + * Will be picking up where I left off with the CP Made Easy guide + * PR the updated sound meter code to work with both CPX and CPB + * Update the CPB NeoPixel Animator code to have streaming prints optional for Gizmo use + * CircuitPython Motor Party + + +@MakerMelissa +* Last Week: + * Worked on Fixing and testing issue with Arduino Deployments + * Worked on fixing an issue with CircuitPython Deployments and put a pre-installer script in place + * Worked on fixing some issues with the Adafruit GFX Library and the ST7735 Mini TFT + * Updated PYOA library to work on PyPortal Titano + * Worked on Porting Python Animated Gif Player over to working on a PiTFT +* This Week: + * Out on vacation all week + + +@PhilM +* Completed research and framework for the new adafruit_sphero library to allow Adafruit devices (focusing on CircuitPlayground Bluefruit) to control Sphero robots (focusing on RVR.) + + +@tammymakesthings +* Began working in earnest on a CircuitPython driver for the MAXIM MAX3010x Pulse Oximeter sensor. I’m porting an Arduino library rather than starting from scratch, but still a lot of foundational stuff I need to learn about, so it’s slow going. I’m sure once I get to the place of “debugging runnable code” I’ll have many questions for the group. :-) +* Prototyped all of the UI stuff for my next project so that when I get the MAX3010x library working, I can finish it + + +@tannewt +* Still a pumpkin. +* Two apple pies turned out well. +* Tackled re-organizing the office/desk on Thursday. Now lots of stuff is zip tied under the desk rather than on top. More reorg to do. +* Started testing out RS232 featherwing I made for interfacing with AV equipment. Having UART troubles on nRF and need to debug it and the hardware. +* Updated gameboy branch and need to swap to DMAing from backup RAM. +* Back to regularly scheduled email, reviews and bluetooth work on 1/2/2020 (next Thursday.) Figured out issue with Apple Media Service (write WITH response only.) So PacketBuffer will be ready for PR shortly. Also need to determine how to know if an AMS attribute is unavailable. +* Planning to do #circuitpython2020 kick off post for 1/1/2020 and will follow up with my own take by the ⅙ meeting. +## In The Weeds +**As this is a notes-only meeting, please save your In the Weeds topics for the next recorded meeting!** + + +## Wrap-Up +**Reminder: The next recorded meeting on Discord will occur 6 January 2019.** + + +**Thank you again, everyone, for your incredible contributions in 2019.
