* Adafruit IO Monthly newsletter was released with a few CircuitPython projects: https://io.adafruit.com/blog/notebook/2019/02/08/adafruit-io-monthly-february-2019/
* This Week
* ADT7410 CircuitPython Guide
* New Crickit CircuitPython Guide, Adafruit IO integration (of course!)
* Event Plug: come on down to the NYC Firmware Meetup to hang out and talk CircuitPython. I’ll have hardware and I’ll be doing a quick talk about the circuitpython community, circuitpython, and contributing to the project. It’ll be fun (I hope!) https://www.meetup.com/NY-Firmware-Meetup/
36:57 @cater
* Carved out some time to do CP stuff!
* Add/move const for ADS1x15 drivers, mode, couple of lines of code
* Add threshold functionality to TSL2561, thought would have more discussion, been merged
38:05 @cgrover
* Stayed in recording studio for extra week
* Broke free just in time for snowmageddon.
* Carved out time at height of the storm, to start coding instance method, turning it into a library. Encountered a few conceptual roadblocks, made steady progress.
* Next project, PCB designs around instance lib. Eurorack control voltage and scaling module
40:10 @charlesburnaford
* Experimenting with NeoTrellis for purposes of doing a autoharp type thing. Got it partially working - major and minor chords. Need to add other stuff. Strumming next. Air harp based.
41:39 @danh
* Just kibitzed on some issues due to vacation. Now back and will be finishing off some remaining bugs for 4.0.0, then adding more BLE functionality, perhaps BLE HID.
@dastels - lurking
42:38 @jerryn
* Took some time to play with particle mesh - non CP but lots of fun!
* Responded to a discord question, found/fixed a bug in the tinylora lib when large packets sent.
* Continued using BLE with crickit and Bluefruit Connect -- great combination
* Began testing ESP32SPI library -- great start
* Next week -- keep poking/prodding in general Especially ESP32SPI.
21:36 @kattni
* Last week:
* ADXL343 fritzing object created.
* 2.13” tri-color eInk fritzing object created.
* Started update to eink guide
* Finalised the ADT7410 guide.
* Ported MotorKit examples from the Python_Motor lib.
* My VCNL4040 boards came in!
* Driver with basic functionality working!!
* Updated `register` to work with multi-byte registers
* Built a breadboard harness for my Saleae
* Found a bug with the `register` update
* This week:
* Continue/complete driver for VCNL4040.
* Next up: VEML7700 driver
* Verify that my fix for the `register` bug is correct, push fix.
* Finish updating eink guide with 2.13” display, 2.7” display
* Finish up Getting Started with CP and BLE guide
* Write Prop-Maker FeatherWing Battle Axe code for Noe and Pedro
* Bundle/PyPI ESP32SPI
* Update OLED FeatherWing PCB files
* At some point:
* Update CPX lib to remove 2.x compatibility
* Finalise ServoKit guides
25:21 @MakerMelissa
* Last Week:
* Worked on Neopixel FeatherWing Library
* 7-Segment Display FeatherWing Library finished
* Did a bunch of reviews
* Fixed a couple issues with HT16K33 Library
* Started writing my first Learn Guide
* Next Week:
* More library work
* More work on the Guide
* Moving, so lots of packing
@mikebarela - lurking
@Mr Certainly - lurking
26:51 @sdw_nj
* Job at microcenter!
* Project: bought multimeter, has cables for USB & DB9 serial, only has windows software, trying to come up with something in Python that works cross platform
* Possibly make a CircuitPython mobile data logger that you could hook up to record
* One feature is graph over time
* Long term thing
28:00 @siddacious
* Last week - Guide published *wew!*, JPEG work/exploration
* This week- Working on JPEG decoding and board assembly (if it arrives)
29:18 @sommersoft
* Last Week:
* circuitpython-build-tools:
* Added `font5x8.bin` to library bundles for `adafruit_framebuf`.
* adabot:
* Just remained confused at how temperamental Travis is being. crons have now passed, but it doesn't appear to be related to any changes to adabot. :shrug:
* FrequencyIn:
* Added user configurable `capture_period` attribute. Has 1ms - 500ms range for now; will decide minimum and maximum after more testing.
* Removed EIC latency adjustment, and simplified the math. Hoping this allows me to approach adjustment from a fresh perspective. Getting about 10% fluctuation in readings from a min/max perspective. This is mostly the variation in the capture period, not EIC latency, since the period can be up to 900us beyond the set capture period. Note: I finally did the math on EIC latency; even with a 48MHz clock (GCLK_EIC), latency per event is in the nanosecond range.
* This Week:
* FrequencyIn
* Adding event counter overflow handling. Increases possible max frequency capability, so that `131,070` (65,535*2) events are possible. This will aid longer capture_periods.
* adabot:
* Work on newline issue for Google Docs transcription
31:05 @tannewt
* A variety of displayio improvements
* Introduces BuiltinFont and Glyph so the built in font can be used by libraries. For boards with a font it is available as board.TERMINAL_FONT. Fixes #1172
* Remove _load_row from Bitmap in favor of bitmap[] access. Index can be x/y tuple or overall index. Fixes #1191
* Add width and height properties to Bitmap.
* Add insert and [] access to Group. Fixes #1518
* Add index param to pop on Group.
* Terminal no longer takes unicode character info. It takes a BuiltinFont instead.
* Fix Terminal's handling of [###D vt100 commands used when up arrowing into repl history.
* Add x and y positions to Group plus fixes.
34:05 @tg-techie
* Long term - working on GUI, 14 days, done.
* Fixed white space breaking of font
* Try to release over the next couple of days
## 44:10 In The Weeds
* @tannewt - Translators: if we’re trying to get 4.0 out the door in 2 weeks, we’re going to minimise the string churn in the next 2 weeks. We can add after stable is released.
## 46:33 Wrap up
