CircuitPython related events coming up
PyCon 2019 returns May 1–9, 2019 to Cleveland, Ohio. Adafruit + Digi-Key is a swag bag sponsor (Special edition red CPX), we’ll also be doing open sessions and more, stay tuned for the blog / Discord for more.
March 11th, London, UK. Meet, learn and share ideas about MicroPython. Nicholas Tollervey will be telling us about the latest features of Mu - a free code editor for Python, MicroPython and CircuitPython devices.
KiCon is a KiCad user focused conference. Held for the first time ever, April 26th and 27th 2019 in Chicago IL. Adafruit is a sponsor - kicad-kicon.com
Send in yours! - @adafruit (pt)
Good PyPortals projects already, thanks ya’ll!

## 25:20 Status Updates
35:00 @brentru
* Last Week:
* Release/bugfixes for CircuitPython Adafruit IO
* NEW CircuitPython Guide: PyPortal IoT Data Logger with Analog Devices ADT7410, Adafruit IO and CircuitPython Using the Analog Devices ADT7410 and CircuitPython to create an IoT Temperature logger
* https://learn.adafruit.com/iot-pyportal-data-logger-adafruitio-circuitpython
* This week:
* Been working on a building a PyPortal IoT weather station
* LOTS of i2c sensor breakouts - SGP30, BME280, VEML6075, and even an anemometer (using the analogin adc)
* Hopefully will serve as an example/reference for using Adafruit IO CircuitPython and DisplayIO together.
* Working on another guide, non-circuitpython related.
@cater - lurking
37:00 @cgrover - text only
* Wrapped up the Range_Slicer CircuitPython library yesterday and am celebrating the successful completion of my first multiple-instance class today (with coffee and speculaas cookies). The class was derived from a synth project that needed to emulate a rotary switch with a potentiometer. It evolved into a general-purpose analog value converter that compresses or expands the input value then quantizes it into a collection of precise output slice values. The class detects input value changes and applies selectable hysteresis when slice edge thresholds are reached to eliminate noisy dead-zone issues, all without any internal delays in the code.
* Applications include converting rotary knob position to MIDI control or note values, analog signal noise processing, as well as level detection and display. Have successfully tested up to 6 simultaneous instances with one of John Park’s projects and will be using it as the primary processing algorithm for a new Eurorack module.
* Next step is to test it with 16 simultaneous instances on the Grand Central M4 Express board. I also want to try replacing the linear algorithm with some non-linear processes that could be used for things like decibels, dew-point, and pH. I may get distracted by using it to create a NeoPixel strip/array color organ with multiple analog inputs and overlapping color zones. No – Must. Finish. GitHub. Documentation. First.
39:20 @charlesburnaford
* Finished MIDI ocarina. Going to build mouth organ
39:28 @danh
* Fixed PWMOut TCC bug (thanks to @kevinjwalters for spotting it)
* Fixed displayio refresh hang when trying to auto-reload
* Reviewed lots of PR’s
* To do: finish cleaning up and fixing a few more issues for next 4.0 beta release
40:20 @dastels (text only)
* PyPortal alarm clock project is done, guide is written. Just putting finishing touches on it and prototyping a case in cardboard. All CP. It turned out nicely, although faster/optimized screen update will make it nicer.
40:28 @deshipu
* Cleaned up and merged the pewpew 10 code and board
* Working on a version of PewPew for a large conference, secret for now
* Got the PewPew working as a USB gamepad
* I finally got the Hallowing going and will test displayio
@jasonp (lurking but may post text)
41:19 @jerryn
* Spent lots of time trying guide examples on the PyPortal.
* Found an issue concerning SPI conflict with displayio
* Impacts use of SDCard on Py Portal
* Impacted test of STMPE610 with displayio and tft featherwing.
* Released updated ATControl with Wifimanager
* Next week -- keep trying things
@Josh - lurking
26:17 @kattni
* Last week:
* Finished writing VEML7700 driver
* Finished writing VCNL4040 driver
* Finished PyPortal guide
* Finished code for Noe and Pedro’s project
* Completed driver for the MCP9600
* This week:
* Library Monday!
* Potentially get hardware for MCP9600 and test driver
* Make Fritzing objects for VEML7700 and VCNL4040
* Update CharliePlex guide to work with breakout/FeatherWing/Bonnet
* Write CharliePlex Bonnet guide
* PyPortal project?
@KingerNorth (lurking)
@ladyada:
* pyPortal and Graphics stuff. Created lib for shapes in ladyada repo - Display_Shapes
* Display button UI element, text with different outines etc, basic UI elements, hypercard buttons - live with it!
* PyPortal demos - soundboards
* Update to Display Text in ladyada fork - to center text and create text bounding boxes - adjusted text entry point - right justified etc. - calculate width of string of font - Text Area and Display Bitmap Font - kind of breaking, needs testing!
28:00 @MakerMelissa
* Last Week:
* Didn’t have much free time last week due to moving
* Made some progress on my RA8875 Guide
* Fixed some bugs in the RA8875 library and got those merged in
* Did a few Code Reviews
* Found a bug in CircuitPython that was crashing it into Safe Mode
* Made some changes to the FeatherWing library to avoid I2C conflicts, but haven’t committed code yet.
* Played around with PyPortal for a bit
* This Week:
* Still won’t have much free time
* Try to actually finish guide this week if time allows
* Do finish up FeatherWing library changes and commit code
* Work on some new FeatherWings as time allows
29:17 @MikeBarela
* Not had as much Python time. If y’all might know the Python on Hardware newsletter comes out Tuesdays, means Mondays are busy.
* A little time with PyPortal - images from Star Trek (mainly ToS) - will be adding to FAQ that display cable came disconnected.
* Guides!
@Mr Certainly (lurking)
@petrofang (lurking)
@quantumobstruction (lurking)
32:30 @siddacious
* Last Week:
* BMP bitdepths
* Mushroom farm datalogger & AIO integration
* This Week:
* Driver work
* More IOM (Internet of Mushrooms) work
* Finally assembling the new board. Boooooo USPS
@sommersoft
* Last Week:
* adabot:
* added import checks for renamed `ure`, `ujson`, and `uerrno` modules.
* updated `-v` command arg to ensure `validate_contents` is always run [first], so that bundles that are in-work are not included in validator results. Does not run/output full results unless explicitly included as a validator.
* FrequencyIn: PR is in!
* This Week:
* circuitpython-build-tools:
* Work on folderizing example files
* adabot:
* Look into library insights results showing zeroes
33:24 @tannewt
* Still very much on vacation so no work since before pycascades.
* Folks in town for a couple more days
*
34:28 @TG-Techie
* A lot of little things - tricorder is unofficially done, works, all the things are doing the things. In a functional state. Revision to MoBo want to make, but don’t need to
* Commit the GUI since it is from all testing stable - release as beta.
* Another kid at school hooked on CP, been wonderful to see
## 43:10 In The Weeds
43:40 @jerryn -- only if time and if considered appropriate since this is not an Adafruit boards
* Ran into issue with using EN pin on particle Xenon
* 3.3 V only drops to 1V when EN grounded
* Would appreciated if someone can reproduce/confirm
* Seems to impact CP startup -- goes to Safe mode if EN used for power control
* No problem if just using USB for power
