## 8:45 Community News
### MicroPython Turns 9 Years Old
MicroPython Turns 9
The 29th of April marked the date on which the first line of MicroPython code was written, which is now 9 years ago! Via the MicroPython Newsletter, Issue 12, here are some highlights at this point:
In the past 12 months the main MicroPython code has seen:
* 1210 commits, up from 817 in the previous year (there are now 13393 total commits)
* 147 contributors, up from 93 in the previous year; thank you to all of you!
* And versions v1.16, v1.17 and v1.18 were released.
MicroPython also gained numerous new features, including f-strings, speed-ups, and many additions to ports. [Detailed list in newsletter]/
MicroPython was again part of Google's Season of Docs, for 2021, where there was a new technical writer who added documentation about the rp2 port, detail about the differences between MicroPython and standard Python, and other things.
GitHub Sponsors has been growing well over the past year, and MicroPython is now receiving USD $4150/month, up from USD $1250/month this time last year. This funding is greatly appreciated and goes towards maintaining the open source code. You can find the sponsorship page here.
### New MicroPython Version 1.19 Coming Very Soon
From Twitter: We plan to release v1.19 very soon, which includes a completely reworked .mpy file format to facilitate freezing Python code without rebuilding firmware.
### PyCon US 2022 Coverage
PyCon US 2022 CircuitPython Team
PyCon US 2022 was held this past week in Salt Lake City, Utah, US. With all the Python happenings, there were plenty of Python on Hardware moments. Above are Jeff, Kattni, and Melissa from the Adafruit CircuitPython Team and CircuitPythonista and library author Rose.
Kattni gave a talk "Simplicity and Fun Learning with CircuitPython". You can see the slides - GitHub (PDF).
Adafruit hosted CircuitPython Open Spaces. Circuit Playground Bluefruit boards were available to code during the events. The code, etc. is available - GitHub.
### CircuitPython 7.3.0 Beta 2 Released
CircuitPython 7.3.0-beta.2, the third published beta release for CircuitPython 7.3.0, is now out on circuitpython.org. It is relatively stable, but there will be further additions and fixes before final release - Adafruit Blog and GitHub.
### Project of the Week: The Boston College Physical Computing Presentations
The Boston College Physical Computing students demonstrated their class assistive technologies project demonstrations, with the projects coded in CircuitPython.
Assistive technology (AT) projects presented to Boston College Campus School by BCPhysComp students: a wheelchair mountable pinball machine, a color cube game for pre-schoolers, a haptic communication tool for a student who is deaf-blind, all powered by CircuitPython - Twitter.

23:04 ## Status Updates
23:30 @danh
* Released CircuitPython 7.3.0-beta.2 last week, to catch up on about three weeks of fixes and additions.
* Fixed a SAMD21 issue that caused displays not to work across VM instantiations.
* Continuing to work with an Espressif engineer on a fix for long delays between I2C transactions for ESP32-S2. The simplest test program worked, but CircuitPython showed timeout errors. I made a slightly more elaborate test program that adds a FreeRTOS task, and it’s now imitating the CircuitPython error.
* Will be systematically testing functionality on ESP32-S3. We have reports of various issues.
26:27 @david.glaude (lurking)
Last week:
* First working prototype of mouse emulation to encode a texture from an in-memory buffer into Game Builder Garage (a “game” on Switch).
Right now:
* Read data from a binary file “GTD” format, list all the GTD files in the flash and process them one by one.
This week:
* Display GTD image file in displayio, file has implicit palette, one byte for the most frequent color index and 4096 bytes for the 64x64 pixels of the image.
26:15 @foamyguy
* Last week
* Found out that I unfortunately deleted my work on the TabLayout that I had started a few weeks back (learn from my mistake and backup early + often and don’t do your development solely on microcontrollers, copy the code back to your PC after making changes!)
* Re-implemented the TabLayout up to the same point that I had it before. Code hopefully slightly better this time around as a silver lining.
* Testing and reviewing various PRs including some typing ones and a Blinka PR to get Blinka_Displayio working on PCs with my Blinka_Displayio_PyGameDisplay library.
* Watched many great talks from PyCon on the online dashboard.
* This week
* (remotely) Helping new contributors working on typing and other stuff during sprints at PyCon, will be reviewing PRs this afternoon after meeting.
* Finish up the TabLayout class and make a PR for it, main thing still needed is touch interaction and I don’t think it should be very difficult once I get into it.
* Implemented a Snake game using displayio primarily meant for PyGamer / PyBadger devices, but could be tweaked to run on others.
* Figured out how to use supervisor.set_next_code_file() to integrate the snake game (or any other script) with the standard PyBadger conference badge example.
31:48 @jepler (not at meeting)
* Last week:
* Floppyio merged! The capabilities are less than the Arduino library, but it still enables reading raw flux & MFM format floppies.
* Pycon! I attended Friday through Sunday for the talks, but sadly had to miss the sprints just due to scheduling.
* While at Pycon I helped each day with an Open Space, letting people learn at their own pace with a CircuitPlayground Bluefruit and helping when they had questions.
* This week:
* I’m exhausted.
* Release Adafruit_CircuitPython_Floppy library which takes care of things like running the drive’s motors
* Blog about some of the talks I attended and some of the things I learned in hallway track. If you have time to watch just one talk video once they go up, I recommend the keynote by Sara Issaoun about the Event Horizon Telescope, which wouldn’t be possible without Python to do the data analysis. However, many talks I attended were amazing, and I always heard that in the other room there was an amazing talk happening at the same moment.
* Soon:
* Taking time off from May 16 - June 24. I might drop in for a Weekly meeting somewhere in there, but being a lot less plugged in is among my goals.
* Learning more about jupyter notebooks, it’s on my list of things to do without hardware while taking time off
32:20 @jerryn
* Not much time available but struggled with rfm9x issues regarding non-default modem settings. The CP library does not play well with the Radiohead library for some settings. Still investigating and puzzled. According to the datasheet, there is good reason for confusion ;-). It will have to wait a few weeks for me to do any more.
* There is an open issue if anyone else is interested in taking a look. https://github.com/adafruit/Adafruit_CircuitPython_RFM9x/issues/70
* Will be away for the next two weeks with little or no internet/cellphone access :-)
5:41 @kattni
* Last week:
* PyCon prep
* Travel to PyCon
* Attend and give a talk at the Education Summit
* Host mini-sprints at the Edu Summit
* Host Open Spaces at PyCon
* This week:
* Host Sprints at PyCon
* Travel home
* No idea, I haven’t looked at my list.
6:44 @makermelissa
* Last Week:
* Finished up the capacitive and resistive Touch Drivers to a point they are basically functioning
* Prepped for PyCon
* Traveled to PyCon
* Attended PyCon
* Helped Kattni with the mini-sprint at the Education Summit
* Helped host the Open Spaces at PyCon
* This Week:
* Helping Host the Sprints at PyCon
* Traveling Home
* Not sure what else.
33:35 @tammymakesthings (missing meeting):
* Last week:
* Only one [Twitch](https://twitch.tv/tammymakesthings) stream this week because of a hardware issue with my computer which I hope has now been solved.
* Continued working on my displayio card deck library
* Submitted a PR for [piku](https://github.com/mraleson/piku) to allow it to work properly with boards that have a lot of flash storage space.
* Did my first [PR review](https://github.com/adafruit/Adafruit_CircuitPython_TPA2016/pull/10) and left comments. Hoping to do more PR reviews and join the review team soon.
* This week:
* Twitch streaming - hopefully Wednesday PM and Sunday AM (Pacific time) and maybe one more popup stream now that I’ve hopefully gotten the hardware issue sorted out.
* Continuing to work on the displayio card deck library. The easy stuff is out of the way, so now comes the hard part of actually displaying cards/groups of cards on a display device.
* Hopefully settling down to a more normal work schedule and regular cadence for CircuitPython-related activities.
34:35 @tekktrik
* Last week:
* Attended my first PyCon - an absolute blast, definitely learned a lot
* Finished moving out, can’t wait to do it again in a few months 🥲
* Finally designed my first open source hardware - the auto-lighting menorah I’ve put off
* Continued reviewing changes to PRs I hadn’t been able to get to
* This week:
* Refactoring the ATECC library
* Finishing up some feature additions to the MAX7219 library whose hardware I’ve been waiting for to arrive in the mail
* Also, unpacking everything in the new place
## 36:30 In The Weeds
@danh - implement auto-backup when writing to CIRCUITPY from an editor or IDE.
