Super. Thanks. Need to make a “mute/unmute everything” control for the media room.

Ah, I haven't delved into it on the Arduino side. I did manage to get a remote control fan working with signals from the CPX with the CircuitPython libraries.

I worry that porting everything could bloat it to the point of not working on CPX, but if it didn't, it's quite worth porting the best features over.

I have to echo foamyguy’s sentiment: Thanks Scott for taking time to explain things and to give me many nudges uphill. Sometimes there are too many daunting “mountains” of programming challenges that stand in the way of the climb of where I’ve wanted to go, and you’ve always been willing to spend your precious minutes point me the right way along the path. Especial thanks for the deep devices as a repository where I’ve been able to find and go back and rewatch (sometimes multiple times) to be able to learn. Many thanks!

Hey Tim!

Can you help me with a strange problem with my brain? It tells my fingers to type Python and it still comes out as Pythin every time.

🙂

inner spade
#

Resistive touch resolves to the lowest resistance point. I don’t know of a way to use eddy currents instead of first-order resistance to detect multiple simultaneous touch. mhomho

#

For resistance touch, it’s usually two layers of linear gradient resistance coating separated by minute spacing dots. The potentiometer analogy is good but doesn’t completely explain what happens when the two layers touch.

wind spoke
#

And one gradient is vertical and the other horizontal?

inner spade
#

^ yes

wind spoke
#

I think I get more or less how that work... but there must be tricks.

inner spade
#

Usually only one gradient is energized at a time. The proportional value is read using the non-energized axis.

#

That’s a great example for learning more about asyncio. It’s motivating me to try it on some projects that are already factored for non-blocking and state behavior.

#

Model railroaders will enjoy the traffic light example.

Is there a number of function parameters beyond which it’s better to pass a dict or kwargs to a function instead of individual parameters? Is that just a stylistic question, or is there a performance benefit to one or other approach?

modern night
#

As far as I know, I swap from lots of parameters as a function input to a class or dict as a function input when it becomes hard for me to keep track of and read lots of inputs. I don't do it for any program performance, but for 'keith is a programmer trying to read his own code' performance. But Maybe there are performance benefits for one or the other that I don't know about

inner spade
#

Function parameters rather than a dictionary is somewhat easier for beginning programmers to understand.

dim wigeon
#

@inner spade Oh for sure. And there’s also a the “when your function has 47 parameters, maybe it’s time to think about refactoring it” thing. 🙂 I’m just curious now if it matters to Python, or just to the programmer. 😉

Cooperative multitasking means you don't have to limit screen updates to one thread.

dim wigeon
#

I’d think you’d want to be careful about not updating the same screen object from more than one coroutine, to avoid race conditions and stuff.

nova totem
#

For my game timer I had a co-routine for each UI element (in this case LED segments) that updated constantly based on a data class. Then another co-routine that handled monitoring the button presses and the logic

dim wigeon
#

Or maybe not race conditions, necessarily, but UI inconsistencies caused by sequencing between the coroutines.

lilac salmon
#

I was thinking about race conditions with passing objects around, but a given async function has to yield to allow another task. So only yield at a point that you can handle objects externally changing.

Nice demo with the switches. I’ve got a lot to learn about async await!

rapid hornet
#

coroutines switch only when you await something

I can imagine that you could get weirdly hard-to-debug behavior depending on the sequencing between the coroutines, though.

But I don’t totally understand asyncio yet either, so I could be totally wrong. 🤷‍♀️

    await asyncio.gather(*tasks)```
async actually greatly simplified the original app.
nova totem
#

The bonus I have found with asyncio is I know when I am giving up control (with await). So then it is on me to ensure that things are in a good state (e.g. do not half update a shared object and await)

grand tusk

It is possible for one task to crash and your app keeps running.

nova totem

You can crash one co-routine only. Found that out the hard way!

I’ve been building a MacroPad MIDI controller in my stream. This discussion is encouraging me to restructure it with asyncio in an upcoming stream. Because I clearly don’t understand it yet.

@smoky island I created a project folder in MS Windows 11. Ran VSCode. Start a terminal. and ran the 'pip3 install circup'. This went successfully. Also 'circup install asyncio'. See the screenshot

I have seen in Arduino code this effect from a sensor and there was code that made a more usable scale.

light stump

I think we need to remember it's a voltage been read from the pin

grand tusk
#

dx/dt to the rescue.

turbid hill
#

it might not be a linear scale

inner spade
modern night
#

Isn't brightness hard to make it feel linear because the eyes are non linear? You could do a silly mapping of

raw_light = sensor.LIGHT 
low_light_adjust = 0.04
high_light_adjust = 0.3
adjust_light = min((raw_light - low_light_adjust)/(high_light_adjust - low_light_adjust), 1)

That way you can easy adjust the boundaries if the ambient light changes too much

#

I was too slow to type the example 😛 That makes sense for why you want to avoid this structure

Maybe just display the light sensor value, don't use it to change anything.

Trying to cement the asyncio concepts into the gray matter. Your streams have helped immensely. Thanks.

#

Sorry about yesterday’s light sensor distraction. FYI, the light sensor measures 1100 lux full-scale. For display brightness, I settled on 10 to 50 lux for brightness value range 0.1 to 1.0

#

Display brightness also contributes to board temp significantly.

inner spade
#

The objects are sensors; some are physical, some are on-screen virtual

Hi Tim. I got here late but I like what you're doing so far.

#

Hey cool people, will hang out a bit and see what new things I can pick up from foamyguy (while doing some minor CAD things)

grand tusk
#

Maybe recalibrate the touch screen.

inner spade
#

Path not important. All screens are different even along the edges.

#

No, don’t have one.

#

That’s a Seesaw internal ADC range limit?

grand tusk
#

That might be a bug in the learn guide code.

#

It would still work because of the way colorwheel works.

#

Hmm, actually I think it would go through the colorwheel multiple times. 🤔

upper sandal
#

hello

inner spade
#

That highlights an overarching issue of raw versus CircuitPython library values. For example, analog inputs are actually 12 bits represented as 16-bits shifted. The max value can only reach 65535 - 15 not 65535. Not enough to matter in the real world.

upper sandal
#

yeah Circuitpython's analogio scales values to the 65535 range, meaning the lower bits will all be 0 if the precision is less than 16 bits

inner spade
#

65520

upper sandal
#

CP colorwheel's input is modulo 256

#

ah I was writing the same thing as CGrover

grand tusk
#

JOHN PARK'S WORKSHOP LIVE 12/2/21 NeoSlider Controller
JP uses 0-1024 for the slider range in this project.

upper sandal
#

the seesaw doc does mention 65535 too

inner spade
#

Philosophically, I’d prefer to have both normalized (0.0 to 1.0) and raw values available if possible.

#

Would like it to be the same across libraries, but may be too idealistic.

grand tusk
#

Yeah, that looks like the same JPW project.

upper sandal
#

they should be normalized to 16 bits to match analogio

#

the seesaw firmware inline doc says
* @return the analog value. This is an integer between 0 and 1023

#

the actual C++ firmware

inner spade
upper sandal
#

1023 for a 12 bit ADC ? 🤔

inner spade
#

4095 like the M4

upper sandal
#

well I have a attiny 8x7 seesaw, so let's see

inner spade
#

Can you preset the slider widget position in code?

dim wigeon
#

Happy Saturday, all! 👋

upper sandal
#

well on the seesaw breakout it does go from 0-1023

grand tusk
#

Yeah I got the same result 0-1023.

#

I think Slider should implement (override) contains and selected.

modern night
#

Hi all, hope everyone's day is going well!

inner spade
#

map_range does the min/max for you

#

Different than Arduino map_range

#

case, slot, and knob perhaps?

dim wigeon
#

Whatever names you end up with, the documentation should include an image of a slider widget, with labels pointing to which color settings affect which parts of the widget, I think.

inner spade
grand tusk
# 
async def read_pot(buffer:RingBuffer):
    seesaw = Seesaw(board.I2C())
    # seesaw analog range 0-1023
    a7 = AnalogInput(seesaw, 7)
    while True:
        await asyncio.sleep(0.1)
        buffer.sleep_time=a7.value/1023.

Added a task to read the seesaw analog input.

inner spade
#

(Spent many years in a recording studio or two, so I’ve seen /operated quite a few slide pots)

grand tusk
#

:mixer: :console:

#

You could slow down the animation to make the pausing clearer.

modern night
#

I really need to spend a few days and explore the async stuff, that seems super useful for ui things

dim wigeon
#

@modern night As I’m starting to wrap my head around asyncio, it seems super useful for all sorts of things.

modern night
grand tusk
dim wigeon
#

I’m building a MacroPad-based MIDI controller in my current stream project, and I’m thinking about how to split the UI and sensor input pieces into async.

modern night
#

Is there an ayncio version of the wifi module? Or is that a question doesn't apply?

dim wigeon
#

It seems like asyncio can really simplify a lot of things I currently have to do with state machine-like logic.

modern night
grand tusk
#

Async wifi is a work in progress. But highly anticipated.

inner spade
#

Excellent example!

dim wigeon
#

@modern night My schedule’s been a bit inconsistent so far because I’m in my last few weeks before a job transition…but I think I’m converging on Wednesday evening and Sunday morning (MST).

modern night
dim wigeon
inner spade
#

With requests implemented in asyncio, I’ll have to up my debugging game significantly.

dim wigeon
#

I’m going to have more flexibility in my schedule once I start my new job, because then my workday will be aligned to EST, so I may adjust some things once I know what that looks like. But we’ll see.

#

Thanks, @smoky island - I’m really excited on both counts. 🙂

#

And my contribution to CircuitPython may not have made me a stronger candidate for the new job, but it definitely made me a more interesting one.

#

Nice! My new job is data engineering for a marketing tech company.

modern night
#

Oh that's a really nice design. I need to try making a board in kicad

grand tusk
#

That would probably work for an irrigation controller.

inner spade
#

Looks like a purple OSHpark PCB.

dim wigeon
#

FETs for switching, maybe? I think that’s how I’d design a circuit like that.

grand tusk
#

That's cool!

modern night
#

That's a super awesome use case

dim wigeon
#

That’s a really snazzy design.

#

My knowledge is patchy when it comes to hardware - I took an introductory electronics class in high school, but I have a ton of gaps in my fundamental knowledge. I’m slowly working my way through The Art of Electronics and trying to fill in those gaps.

#

I have gaps in my math knowledge, though, which makes self-study of a book like TAoE hard. 🤷‍♀️

My dad just told me about a guy he met recently who decided after a long career in medicine that he wanted to pursue his passions. He went back to college in his late 70s, and at 86 years old he earned a PhD in physics.

I like that @smoky island started with a working program, then added asyncio features. It's not the only way to do it but it worked well.

What's your best advice on making 3d printed holes intended to directly accept screws? Is it "give up and use a captive nut"? Personally I use heat-set inserts but for a guide I want to not require their use..

Could neo magnets work here?

On the magnet subject, do they affect WiFi reception?

the tolerances sometimes give me grief

@unreal bay never measured wifi. I suppose you could test before you decide

Wanted to attach a project box to a wooden pole with magnets but the WiFi in garden is already weak.
I'll have to test it properly at some point

upbeat coral
#

Not professionally speaking but I assume a neo magnet wouldn't interfere with the electronics too much or they wouldn't be used in hard drives. Again just my supposition.

unreal bay

That was my hope! In theory if the magnet field/flux doesn't change it won't affect things, or so my rudimentary understanding suggests
