### CircuitPython Day is 8-6-2021, Set Your Calendars!
8-6-2021 is the Snakiest day of the year and it's also this year's CircuitPython Day!
### CircuitPython and MicroPython – Talk Python Live Stream
On July 8th, the Talk Python Live Stream host Michael Kennedy had guests Scott Shawcroft and Damien George to discuss how MicroPython and CircuitPython are working together to further embed Python onto all the small things - Adafruit Blog and YouTube.
### CircuitPython 7.0.0 Alpha 4 Released
CircuitPython 7.0.0-alpha.4, has been released. It is relatively stable, but contains a number of issues still to be addressed for 7.0.0. The Python API’s it presents may change.
Notable additions to 7.0.0 since 6.3.0 include:
* Support for the CircuitPython development workflow over BLE.
* Camera support on ESP32S2.
* The keypad key-scanning module.
* Run-time customization of USB devices.
* Merging in of MicroPython fixes and enhancements as of MicroPython 1.16.
* Simplifications to the RGB status LED codes.
* A clocking fix for a few samples of RP2040 boards.
### Mu 1.1.0-beta 5 is now out
Mu 1.1.0 Beta 5 is now available on their downloads page. It is a beta release so it may contain bugs or unfinished features. Bug reports or feedback via GitHub is solicited. The Mu Team had hoped for a regular (fortnightly) release tempo. Due to the voluntary nature of Mu’s development and because some of the updates in this release were quite challenging, this release is a LOT later than the developers had planned - Mu Blog.
### Python, C and Java all compete for the most popular programming language in TIOBE Index
The July TIOBE index shows C, Java, and Python are in a near dead heat for most popular languages - TIOBE and Adafruit Blog.
### 2021 Global IoT Trends Report
Newark reached out to their global customer base with an IoT survey between September 2020 and December 2020, compiling the results into their 2021 Global IoT Trends Report - Newark and Adafruit Blog.
### Sphero
Now that my Sphero RVR drives to specific coordinates on the floor, I can get my apartment delivery system online for use during quarantine in HCMC. Powered by an Adafruit Metro M4 running CircuitPython and elements of the SDK - Twitter.

Library updates in the last seven days:
**Updated Libraries**

* [CircuitPython_Community_Bundle](https://github.com/adafruit/CircuitPython_Community_Bundle)
Overall: We’re still working through all the currently open PRs, and continuing to try to get through the older ones. It’s great to see all the new contributions to both the Adafruit libraries and the Community Bundle. There have been a number of significant changes to the libraries (and in the core!) that are breaking changes. The plan is to aggregate a list of all the changes and prioritise in what order we should address them, in terms of updating code examples and Learn guides. I will be doing that this week, so we can get started on updating all the relevant code and guides. Thanks again to everyone who has been helping out with this!

## 19:41 Status Updates
@anecdata (lurking)
31:27 @danh (not at meeting)
* Released 7.0.0-alpha.4 last week, with a late fix for display glitches on MacroPad.
* Continuing to debug audio issues on RP2040.
31:48 @foamyguy (unable to attend today)
* Last Week
* Working on changes related to Group max_size removal
* This week
* Working on changes and reviews related to OnDiskBitmap pixel_shader
19:59 @jepler
* Last week:
* Calculator project: Guide Coming Together
* Space Savings by Splitting Type Objects: WIP
* Smaller space savings from string compression
* Immediately spent some of that space on adding `ticks_ms`
* Worked on the library that will become `adafruit_ticks`
* Learned enough about USB descriptors to make two descriptors that support NKRO, one of which is also compatible with at least one PC BIOS menu (dell) as well
* This week:
* Wrapping calculator project
* Hopefully wrapping type object split
* “Out of office” on Friday
* Publishing `adafruit_ticks`? This library will be targeted at pypi as well as circuitpython and I haven’t done that in the bundle yet
* Making plans for fixing guides that are incompatible between 6.x and 7:
* ulab
* OnDiskBitmap
* ???
* Soon:
* Working on capturing JPEG images from OV2640 camera
24:10 @jerryn
* Fielded some forum questions in regards RFM69 and RFM9x
* Need to “scrub” RFM69 comments -- some outdated
* RFM9x had CRC disabled by default. This is opposite of the RadioHead library used by Arduino.
* Will bring up “in the weeds”
25:04 @kattni
* Last week:
* Started the MacroPad library
* Created the new `rainbow` module in CircuitPython as a new home for `colorwheel()`
* Removed `colorwheel()` from `_pixelbuf`
* So far today:
* Finished and PR’d the MacroPad library.
* This week:
* Rename `rainbow` to `rainbowio` to avoid naming conflicts on PyPI for Blinka
* Ensure `rainbowio` is working with Blinka.
* Test and merge an outstanding PR on adafruit_pypixelbuf if possible
* Sort out renaming `_pixelbuf` and `adafruit_pypixelbuf`
* Remove `colorwheel()` from adafruit_pypixelbuf in the new adafruit_pixelbuf lib
* Start putting together a list of major changes in 7x and libraries, and prioritise what needs to be addressed first.
27:47 @MakerMelissa
* Last Week:
* Worked on Machine Learning Cat Detector guide
* This Week:
* Finish up guide
* Work on the WebSerial ESPTool some more
28:05 @tannewt
* Very short week last week. Went camping this weekend too!
* Last week got a serial console on code.circuitpython.org and hooked up usb serial and ble serial to it. Still very rough design.
* This week will be refining it plus bug hunting things in CP. Need to get caught up on mobile work too.
* Finishing up the micro:bit v2 PR
## 32:05 In The Weeds
@jerryn
RFM9x library has CRC disabled by default in contrast to the Arduino RadioHead library that has it enabled by default. If they don’t match, packets are ignored. This can be dealt with by documentation or a change to one of the Libraries. It could be considered a “breaking change” because any existing code would not be compatible with new code if the defaults are selected. I’m curious how folks suggest dealing with it. Enabling the CRC is trivial `rfm9x.enable_crc=True`.
33:38 @DaveP
The Pico SDK does not reset the StateMachine program counter when a pio_sm_restart() is called. Micropython has implemented their own program counter reset code during a restart. Which way do we want it to work?
## 35:27 Wrap-Up
Next week the meeting is on the 19th
