I remember watching that a while back, really cool tool

gusty wedge
#

Yup, it is. My bad.

#

In wifi they call those two "suscriber unit" or SU, and AP.

#

Yeah, just by moving the tools out, it should shrink the lib a bunch.

strong acorn
#

UDP is not implemented properly / fully in current esp32spi, but can be used with workaround

gusty wedge
#

no problem with the image here.

strong acorn
#

e.g., battery level on co-processor

#

(GetAnalogRead)

#

Yes, PWMOut.py and digitalio.py are abstractions to make the API like circuitpython, using the underlying NINA capabilities

fair fulcrum
#

@rapid hornet What is your reason for choosing Sublime Text? it there particular things you like about the way it works?

gusty wedge
#

_esp instead of esp? (line 101)

strong acorn
#

We'll need pinouts for each variation of ESP32 co-processor, to be able to use native circuitpython digitalio, or does digitalio not really care?

#

Can add pins "34, 35, 36, 39" as inputs (maybe 37,38 on some boards)

gusty wedge
#

On twitch, you can "move" the users on your stream to Nina's (once you are done)

#

Good stream @rapid hornet, thanks. Yeah, keep doing them.

strong acorn
#

Looking forward to using the re-architected network stack 🙂

fair fulcrum
#

i would get lost so fast moving that much stuff around.

rapid hornet
#

totally covered this up and missed these chats. sorry all!

#

@fair fulcrum I like how sublime is fast. I don't use most of the fancy features

#

thanks @gusty wedge

fair fulcrum
#

=^-^=b

rapid hornet
#

@strong acorn native digitalio won't work with the coprocessor pins

strong acorn
#

that was my confusion

#

I thought there was a mention of using it

rapid hornet
#

just using the DriveMode and Direction values

Hello.

#

First off, Happy 4th!

#

I’m thinking of ordering the oshwa badge assembled. However, @wanton dome, you mentioned that is very similar to the Adafruit CLUE. So, I’m now wondering, what additional features does the badge have? And should I get a CLUE to play with for now, or should I just get the badge?

wanton dome
#

@cobalt harness The badge is a watch, so there's that. In terms of sensors they both have the same type of sensors, but I was wrong about them having the same exact sensors. Close, but not the same:

CLUE vs OHS2020 Badge
9DoF IMU
LSM6DS33 Accel/Gyro + LIS3MDL mag vs LSM9DS1

Temp/Hum/Press:
SHT Humidity+ BMP280 temp & pres vs. BME680 Temp, Press, Hum

PDM Mic vs. SPH0645LM4H-B Microphone

Buttons/Pins:
2+Buttons + Microbit conn., reset  vs 4 user buttons

Battery Connector:
JST PH-2 vs JST SH-2

Both:
APDS9960 Proximity, Light, Color, and Gesture Sensor
Quiic/Stemma QT Connector
#

You'll have to look up the datasheets to see what the functional differences between the sensors are but generally speaking they're all very similar and provide the same capabilities

#

@cobalt harness You said you were thinking of ordering the badge assembled; where from?

#

One of the designers, Michael Welling is going to do a crowd funding campaign for them but he's going to do some modifications to the design first

Hi.

inner spade
#

Music audio level is very low, -24db

#

Voice audio level is low, as well.

#

@haughty quiver Better, level is about -12db now. No clipping.

#

Board sound level is very low on this end.

#

No echo, though.

#

Much better! Putting the mic closer to the speaker helped significantly.

gusty wedge
#

Hi.

solid wyvernBOT
gusty wedge
#

Very cool way... using direct midi notes/ is the worst :).

wind spoke
#

Why not just do index+45 ?

inner spade
#

Relatively simple in CircuitPython: ```python

list of valid note names used by note_lexo, note_name, and name_note helpers

note_base = ['C', 'C#', 'D', 'D#', 'E', 'F', 'F#', 'G', 'G#', 'A', 'A#', 'B']

def note_to_name(note):
""" Translates a MIDI sequential note value to a note name. Note values are
of integer type in the range of 0 to 127 (inclusive). Note names are
character strings expressed in the format NoteOctave, such as
'C4' or 'G#7'. Note names can range from 'C-1' (note value 0) to
'F#9' (note value 127). If the input value is outside of that range,
the value of None is returned.
"""
if 0 <= note <= 127: # check for valid note value range
return note_base[note % 12] + str((note // 12)-1) # assemble name
else: return None # note value outside valid range

def name_to_note(name):
""" Translates a note name to a MIDI sequential note value. Note names are
character strings expressed in the format NoteOctave, such as
'C4' or 'G#7'. Note names can range from 'C-1' (note value 0) to
'F#9' (note value 127). Note values are of integer type in the range
of 0 to 127 (inclusive). If the input value is outside of that range,
the value of None is returned.
"""
name = name.upper() # convert lower to uppercase
if (name[:1] or name[:2]) in note_base: # check for valid note name
if '#' in name: # find name and extract octave
note = note_base.index(name[:2])
octave = int(name[2:])
else: # find name and extract octave
note = note_base.index(name[0])
octave = int(name[1:])
return note + (12 * (octave + 1)) # calculate note value
else: return None # string not in note_base

#

Note to frequency to note is fairly easy, too.

# 
def note_to_frequency(note):
    """ Translates a MIDI sequential note value to its corresponding frequency
          in Hertz (Hz). Note values are of integer type in the range of 0 to

Hi there!

tiny axle
#

is that whats known as rested development (sorry word puns)

#

Nope don't remember it

inner spade
#

Yeah. Multithreading in MakeCode is so much simpler!

tiny axle
#

Where is the speaker on the microbit, I haven't looked at mine in ages

cinder wind
#

actually... having a threading model in CircuitPython would be really useful (and doesn't have to be "real" threads, just coop multitasking with a "yield" construct)

tiny axle
#

Multiple voices

dense marlin
#

Multithreading must be supported by the language or by the microcontroller or both? In Open Roberta I can’t multithreading with microcontrollers also supported in MakeCode.

cinder wind
#

You can do cooperative multitasking without any language support with a timing library. This is how a lot of Arduino libraries work, they'll have an 'update()' method that should be called as frequently as possible. Not sure how this maps onto MakeCode. For CircuitPython, looks like this is the issue where people are talking about it: https://github.com/adafruit/circuitpython/issues/1380

GitHub
Simpler mechanisms for asynchronous processing (thoughts) · Issue #...

These are some strawman thoughts about how to provide handling of asynchronous events in a simple way in CircuitPython. This was also discussed at some length in our weekly audio chat on Nov 12, 20...

Clearly I love this stuff and could have gone on another hour or two :]

cinder wind
#

can't believe how easy it is to do MIDI on MakeCode

inner spade
#

It's a very well thoughtout extension.

haughty quiver
#

I looked up and was like "uh oh, I need to end this, there's usually another show scheduled right after!"

#

The biggest questions I have are: what would it take to add USB MIDI support proper (instead of serial over USB and a software bridge) and can we get the extension on MakeCode Arcade and CPX.

#

Hi @dense marlin !

#

Thanks @gusty wedge

dense marlin
#

Oh, Midi on Arcade and CPX would be nice.

Hey @haughty quiver I tried setting up serial midi but to no avail. Any suggestions?

haughty quiver
#

If you are using an os other than Catalina you can try Hairless Midi instead of that Python script.

I only have catalina

haughty quiver

And you can't rollback your time machine backups so I didn't wanna risk anything

@open girder What's the difference between I2C and SPI?

echo canopy
#

Question about Adafruit IO

This week there was an update to a certificate that the connection needs

Can you explain more about why this is needed ?

And if in the future if there would be a way to update the certificate with a “drag and drop drive” like Circuit Python so you don’t have to upload the sketch again (arduino)

wicked copper
#

that drag and drop stuff is actually using the bootloader, not circuitpython itself. Someone would have to write an alternative bootloader for arduinos

echo canopy
#

True

noble grove
#

Why does the i2c terminator need two connectors?

distant junco
#

Question - I'm dreaming of adding a second TFT (SPI) to the PyPortal. Unfortunately, there isn't a SPI hardware breakout. So I guess I could implement software SPI... if I use the D3/D4 with the SWDIO and SWCLK. Is that even do-able? Or recommended?

wicked copper
#

so I2C for multiple relays, SPI for live temp sensors (example use case, would this make sense?)

Are you still using the HDMI video capture adapter from the previous week?

Question: I just encountered my first set of bad NOR flash chips - And I thought they were basically fool-proof.... do you folks see bad flash chips on your boards? Do you flash test them?

Question: When a board has SMT components on both sides, is it just two trips through the same kind of reflow process, or does the second side need special handling?

junior hornet

which pcb board manufacturers do you guys like to use for large volume production (bare boards)?

Follow up question — so in theory I should not have to worry about a certificate as much on a ES32 vs ES8266 boards ? Less having to update 1-2 year timeframe .. thinking about expanding the number of WiFi devices

So I'm planning to use 15+ 18650 batteries in a 3s5+p config but I'm not sure how it will work out. Do you think this will be the best way of using them? (Load will be 5v 6+A.)

Yeah - fresh board, and small number of rewrites - the post has all the details, and I created a simple flash tester for Express boards --- posted in a gist

He's the first human-form cylon.

"Human form"

He is our ideal form, but that level of sophistication was impossible to mass-produce -- hence why we're in the form we're in currently.

So, Lars is what we are to become...

Traffic Jam

I picked up three giant traffic lights at a surplus store, because really, how I could I pass them up at $12 each? I thought it would be a great display item / game / piece of artwork for the Alpenglow Indsutries shop, and the perfect project to teach my team beginning Arduin...

Big Red Button Enclosure by alpenglow

Big red arcade buttons are great additions to any project, but they need an enclosure to be able to stand up on their own. This one has been designed specifically for 60mm buttons, with enough internal space for a wire harness that uses right angle quick connects, and has an ...

The cool thing would be to have something physical to control the webcam. Like a neotrellis...

Maybe linear motorized pots, or rotary.

This is wicked cool @azure halo

I'm getting some hardware from TingerGen, which is a spinoff of Seeedstudio. They have a microbit line, and I want to use them but with Clue.

Do you "sniff" (let's say on the ethernet side) the trafic you generate to debug your code?

Is it possible to do low level things like Scapy when using a co-processor and high level API like this?

you can certainly sniff wi-fi with Scapy from a separate machine, if that's what you're asking

Packet "forging and sniffing" in Python.
