@crimson ferry I'm studying/reimplementing some sample code down in esp-idf's components/driver/test/dac_dma_test, since there's not an esp-idf API available.
From my internal notes:
To make their test, in tools/unit-test-app, run
idf.py -T driver flashcode lives at components/driver/test/dac_dma_test
One of the DAC outputs was weird (clipped?) on my Kaluga (in this test AND in circuitpython AnalogOut), while my Metro ESP32-S2 was fine with an AnalogOut test. I didn't test a 2nd Kaluga, but didn't find any reason in the schematic for this to be the case so it may be a damaged module.
that's about all I know, CP isn't building yet, let alone getting far enough to see if it "does anything". Cooperating with AnalogIn/Out and SPI(!) also needs to be written. DAC DMA somehow reuses the SPI3 peripheral's DMA function.
crimson ferry

@tulip sleet The Windows issue was a red herring. They figured out that if they press down on the USB connector while it's plugged in, it's ok 100% of the time. Multiple cables make no difference, so the connector is loose. They're debating on reflowing the connection or needing to replace the connector. And deciding whether it's worth the repair, or simply replace it. Anyway wanted to give you the final update. We can add "loose USB connector" to our lexicon of potential issues for future reference.

@onyx hinge I have a simplified version of the code, and I think I know how to explain it, but I'm uncertain. Had to redo all of these examples because of a complete refactor of the final example, and they all build on each other. Bleh. Better code, but still. Guide page needs to be redone. Anyway. Here's the code.
import board
import digitalio
pir = digitalio.DigitalInOut(board.D10)
pir.direction = digitalio.Direction.INPUT
while True:
if pir.value:
print("Motion detected!")
while pir.value:
pass
Ok, so when the value is first True, it prints, and then it waits though the rest of the signal before beginning the loop again?
Which has the same effect as the previous code?
onyx hinge
That sounds accurate. I'd call these two while-loops "nested loops".
idle owl
Oh right, that was mentioned, but I would have forgotten to include it.
onyx hinge
Since a while loop runs over and over again as long as its condition is true (and there's no "break" statement encountered inside it!), while pir.value: pass is a way to say "wait until pir.value is False", right?
idle owl
Should be, yes.

which seems a bit backwards but there you go ..

gloomy shuttle
I am listening back to the meeting from today as someone who has been hacking on the nunchuk library, I don't think the problem is completely understood. I think I had solved the speed read issue.
the i2c read was only delayed because in the library as it exists it reads the data for each property.
tidal kiln
@gloomy shuttle yep. that's the basic issue. the question was more best python-y way to return all the parameters from the single read.
thorny jay
I am afraid the discussion was done without watching the PR you did this week-end. I tried to explain that in the chat but that did stay theoretical discussion.
gloomy shuttle
I think my original PR solved both of the issues that Carter mentioned today. What it does is each property calls read_data and the read_data wont update the buffer if it had been updated recently. I introduced _I2C_BUFFER_UPDATE_DELAY for this reason. then the property parses out the sensor information accordingly.
thorny jay
For using the library for the tablet, I also want to make sure that X and Y are read at the same time, as I don't want the cursor to go to X from T1 and Y from T2. I need the X and the Y from the same I2C response from the hardware.
This is not a problem anymore.
Please @tidal kiln, have a look at the PR and if you have a better way or better API, document what you think would be best.
gloomy shuttle
I think I would like to do the PR over again for clarity and remove the values function as I don't think it is concise. I think the property method was better for parsing the buffer.

There is not a lot of shared code between the libraries. the only thing that is really shared is the read_register and read_data functions, but I do think there is some benefit to having them all in the same location like the WiiChuck library for Arduino is.
slender iron
either way is fine with me
my only concern is that each peripheral has it's own file to import

atomic summit
I have a question about this "pin in use" thing. Due to this I am unable to reference an IO from both DigitalIO and AnalogIO right?
slender iron
you can't at the same time
atomic summit
So if I wanted to have IO4 as an ADC input, pulled low I can't do it.
slender iron
are you going to rely on the value of the pull down resistor?
atomic summit
As there is no Pull on AnalogIO and I can't do them at the same time.
slender iron
what are you trying to do?
atomic summit
I'm curious to try, yes. I don't need exact.
I'm trying to remove a voltage divider on the Ambient light sensor which will always sink to GND and use the pull down on the IO instead, so I can set the pin to high impedance and have the Amb sensor suck no current.
slender iron
it's not possible from circuitpython currently
atomic summit
what the value of the resistor is, is really no important, from board to board...
Ok, I didn't think so, bummer. Ok 🙂
the Amb sensors sucks 30uA 😦
And that's with a 100k resistor - i can go higher, but then introduce more erratic results - and the ESP32's ADC's are already underwhelming as it is.
slender iron
this is the first time I've heard of someone doing that 🙂
atomic summit
Someone on my stream recommended it today... I have also never heard of it... 😉
The pull up/downs are "supposed to be" around 47k. I don't care if that is +/- 30% to be honest, so long as it's consistent on that pin on that specific chip.
slender iron
right
atomic summit
Ok, well something for the wish list then 😉
slender iron
yup, that's what issues are for
atomic summit
I found the 2 culprits on stream today that are keeping my FeatherS2 at 85uA in deep sleep (I'm totally find with 85uA as the FeatherS2 was never about best in class deep sleep) - but I was able to get it to 31uA
slender iron
nice!
ornate breach
Not bad
atomic summit
I can move the AMB sensor to LDO2 so it takes no current in DS, but I lose the ability to wake the ESP32 with it - as I deliberately connected it to an RTGPIO
But I have no idea if that is even a useful thing for anyone
atomic summit
@slender iron so if I was to do a "new revision FeatherS2" with some changes on it, how would that usually be handled in CP ? Would I have to introduce another board?
slender iron
it depends on what the changes are
atomic summit
Surely, Adafruit have had board revisions in the past pin changes or feature changes, and I don't see different boards for them.
slender iron
they are usually identical from the software side
we do allow multiple flash chips for that reason
atomic summit
So lots of folks are asking me for a VBAT voltage divider. That would be another pin definition, but would only work on new revision boards.
slender iron
if you are changing any pins around you'll want a new board
if you are using a currently free pin then you could probably just add it
but having it be clearly distinct will save you headache in the long run
atomic summit
Not changing pins, but adding new currently unused ones.
slender iron
if they are unused you could then just add the pin defines
atomic summit
How would I make it distinct? any advice would be welcome!
slender iron
clearly labeling it in silkscreen
atomic summit
but if someone uses that on an older board where the pin is not connected, they'll get weird/wrong results
slender iron
yup! that's why it need so to be obvious they are using an old rev
adafruit boards include a revision letter on them
atomic summit
Right, ok. Gotchya!
I have my P number. P1, P2 etc
Ok, this is great info, thanks. I'm not 100% sure I'm going to add anything new yet.
But great to know I can without having to make a new board definition@
crimson ferry
is there a P2 now?
atomic summit
P2 is current and P3 is coming... but no changes for the user on P2 (just some DFM changes for me) and P3 has fixed silk for IO14 (current has IO13 by mistake)
no functionality changes
crimson ferry
cool, I have P0 and P1, I won't confuse myself by getting P2 right now 😉
actually I'll get whatever Adafruit ships me o_O
atomic summit
I have to say - on my stream today I was showing my FS2 and CP on the PPK2 - looking at the deep sleep stuff - it may have looked like I bagged CP a bit about power cost in boot/wake/start USB time etc...
slender iron
in my ideal world circuitpython would be able to read what board version it is but that'd cost board $$$
I won't watch it then 😛
we know there is more room to optimize things
atomic summit
but I did state very clearly that CP on ESP32 is brand new, and deep sleep only just came in this version and there are stacks of optimisation opportunities still
slender iron
I'm more interested in bringing deep sleep to more ports
atomic summit
exactly... I didn't want to sound like I was bagging CP - but I was aware at the time it might have come across that way.
So letting you know here in advance incase it comes out in the wash 🙂
DS so far is excellent on the ESP32/CP - it's more about the 2.5 Seconds of boot time at "full power" before my CP code starts running
atomic summit
and the PPK2 really showed that as a concern as it look longer for that to happen, then for my actual code to run and go back to sleep.
slender iron
@atomic summit did you get to editing circuitpython code to partition the start up time?
that'd be the way to find the issues
atomic summit
Sorry, what do you mean?
slender iron
editing the circuitpython c code
atomic summit
make a smaller partition for faster boot ?
Oh, no.. focus was on DS and FS2 debugging...
slender iron
you could figure out how long it takes to enter CP main() for example
atomic summit
It was a hardware deep dive today... but I think it's due to the flash size. I think the bigger the flash, the longer it takes to boot.
The Q is.. when only running on battery, how do we detect that and stop the USB side from even starting up?
That would be the ultimate fix 🙂
slender iron
why do you think usb is the problem?
we do know the wake reason and try to skip normal startupy things when waking from deep sleep
(or at least we should)
we should only slow start on a power on reset
atomic summit
I can see on the PPK2 timeline when my LED turns on and kinda work back from there...
slender iron
right, that makes sense
atomic summit
LED on is the first ting that happens after imports- and LED on is about 60% of the way into the graph
slender iron
did you move it to before imports?
or after native-only imports
pulls up the stream
atomic summit
import board
import digitalio
import time
led = digitalio.DigitalInOut(board.IO13)
led.switch_to_output(value=True)```I could move time, & alarm after, but they should be smallish
slender iron
ya, they are all native so I would expect it to be fast
atomic summit
right, so anything pre first user code import is out of the users hands...
slender iron
yup, so we'd need to optimize it
atomic summit
and I know in MP for instance (no native USB) my TP gets to user space code in sub 1 second
with 4MB of flash
so I'm assuming the extra flash size and native USB is the overhead
slender iron
right, so the question is "what is slow"
and you could add pin level setting in the circuitpython c code to find it
atomic summit
I'm not overly concerned right now.
Oh, turn on the LED in c? see where that happens?
slender iron
right, I'd start by putting one at the top of main() so see how slow the bootrom and tinyuf2 are
atomic summit
Ok, I'll find some time to look into this! Thanks for the tips 🙂
slender iron
np. thanks for looking into it!
fossil gorge
Out of curiosity, where/when do you stream @atomic summit ?
slender iron
fossil gorge
Cool, thanks @slender iron! Always love seeing what others are doing and soak up what I can
atomic summit
3.5 hours today... that's about 1.5 hours too long... but lots of folks wanting to see the final solution to the DS probe
slender iron
🙂
that's why I do timecodes in the stream now
here is an example of what we should be doing: https://github.com/adafruit/circuitpython/blob/main/main.c#L473-L477
when starting on power on we want to be cautious and delay
likely we need more of those 🙂
or that one isn't working
common_hal_mcu_processor_get_reset_reason() == RESET_REASON_POWER_ON
atomic summit
yup, removed my comment, sorry
slender iron
np
atomic summit
I looked backwards to see how skip_boot_output was set, not forwards, sorry!
slender iron
🙂
atomic summit
Have we confirmed common_hal_mcu_processor_get_reset_reason() == RESET_REASON_POWER_ON actually works?
I guess I can light up my led in there.. to see if it fires
atomic summit
hahaha
so if (serial_connected() && serial_bytes_available()) { detects if USB is connected ?
slender iron
ya, that should do usb
atomic summit
so supervisor_set_run_reason(RUN_REASON_STARTUP); wont alter the VM wake reason?
slender iron
I'm open to not starting the usb peripheral when waking from deep sleep
atomic summit
If USB is connected it would be fake deep sleep right ?
slender iron
there are multiple reasons. one is why the vm ran and one is why the mcu ran
right, with usb you'll pretend to deep sleep
slender iron
@atomic summit when circuitpython resets pins it should disable all pulls and all buffers
we likely need to "deinit" pins for the rgb led though

E.g. ble_mesh, wifi_mesh, zigbee_mesh, etc. Do you expect there to be a Python helper library. _bleio might be the module: low-level impl whose API can change and is not guaranteed. We always use the adafruit_ble library on top of _bleio.
esp-mesh looks to be only wifi
analog bridge
thing about mesh is that the stack is capable of handling everything scan/connect/re-connect/self-heal... so supporting python library isn't needed
I am thinking of something like following :-
import mesh
wifi_mesh = mesh.wifi.WiFiMesh(...)
ble_mesh = mesh.ble.BLEMesh(...)
# common functions from here
mesh.start(wifi_mesh)
# or
mesh.start(ble_mesh)
also since you won't be doing two different mesh types simultaneously... there isn't a need for supplying that particular mesh object again and again in the subsequent calls
slender iron
I also don't think we need a hierarchy. they can still share APIs without it
analog bridge
@slender iron since you are here... question for you.
Is it possible to get the WiFi object with ssid, bssid, passwd... parameters so I can pass it directly into mesh.wifi.WiFiMesh(wifi_object)
slender iron
the wifi object doesn't have those items until you connect
does it make sense to connect before having a mesh?
analog bridge
ESP-MESH takes over the WiFi and LwIP stacks... the docs explicitly say that external calls will tamper mesh functioning... so no wifi simultaneously with esp-mesh
on power_on several devices broadcast with same mesh network parameters and start forming a network... they then choose a root node... the root is responsible for connection with WiFi...all of this is handled by ESP-MESH
slender iron
right, I'm not sure it makes sense to make a wifi object to start
analog bridge
I am trying reduce the number of arguments being supplied to wifi_mesh object constructor... its already 6... with wifi parameters added it would surpass 10
also there is a possibility of conflicts with things like password... is it for mesh or for wifi

ionic elk
Dumb core question, but can we add constants to a class in Circuitpython? Are there any classes that do that?
sacred blade
@ionic elk Depends on what you mean by "constants". If you mean "something that can't be changed", it's (very) hard. If you just want a bunch of values you can refer to elsewhere, you can define them as class members. Usually they are all upper case to mark them as 'constant'.
class Foo:
BAR = 42
If those constants are integer values, you can write :
class Foo:
BAR = const(42)
This is a micropython extension, and the compiler will be able to optimise references to Foo.BAR in the module, making it as fast as if you used 42 directly.
ionic elk
Thank you, but I mean within the C implementation of a Circuitpython module, is it possible to create non-function attributes within a class (I said "constants" because the ssl module has a large section of these under that label https://docs.python.org/3/library/ssl.html?highlight=ssl#constants)
I don't recall any examples of this in a C-implemented Circuitpython module in the shared-bindings domain that I've seen, but they might just not be present in the modules I've worked on.
sorry for being vague.
my Python vocabulary still isn't super amazing, I've only really started on that this year
sacred blade
@ionic elk no problem 😉 but I have no experience regarding the C implementation. However, I think something like MP_DEFINE_CONST_DICT could be used, like the one used in board.c to map pin names to pins. Don't know if it's usable for a class.

slender iron
@tulip sleet do you have a plan for making 6.1 stable?
I wonder if an mpy with an f-string works in a build without f-string
I suspect it does because I think it's a transformation to string.format()
atomic summit
It makes total sense for Espressif to offer PIDs for smaller companies making products using their USB enabled MCUs. Just like Microchip, Silabs and other vendors do.
This is going to make it much easier for smaller companies like me that might only make a small range of USB enabled products over a few years, so I'm glad Espressif have done this.

atomic summit
@slender iron I noticed you allocate a unique PID for CP, Bootloader and for Arduino. Any reason why they all can't use the same PID? It's not like a single board can be used in Arduino and with CP at the same time.

Not at the same time, but the host may want to behave differently depending on what is running on the board.
atomic summit
ok, but why can't they still share the same PID? So long as the PID is unique to that board in both environments?
I'm obviously going to grab some PIDs from Espressif for some upcoming boards and I'm trying to work out if I really need to ask for 2 (or 3) per board to cover CP and Arduino.
thorny jay
Let's wait for Scott, but I believe he discussed the topic in one of the Deep Dive video.
stuck elbow
I think they can, if you want to.
I mean, PewPew uses the same PID
because I only had one
atomic summit
@stuck elbow Yeah I know it can be the same, that's why I'm curious about why Adafruit assigning multiple. @thorny jay I remember Scott talking about ti on one of his streams, but can't remember which one 😜

I had removed them at some other point and ran into issues but that was without the update() function approach.
tidal kiln
yah. that does seem to work on qt py. let me play with that some more. i feel like there was some reason those delays had to stay in there. it would be great if they could go away.
gloomy shuttle
I just tested it on the featherS2 as well and it works.
tidal kiln
@gloomy shuttle it'll have to wait until tomorrow before i can test things. but if we can do the i2c read without those delays, we may not even need a fancy approach for speeding things up. dumping them is an instant 20ms savings.
gloomy shuttle
I think you may start getting bad data if you try to call the read_register too quickly in a single loop of a code.py.
tidal kiln
yah. i just did quick test like that and it seemed to work.
but i thought i tried that when i first wrote that library
i based the library on existing arduino ones, which had those in there
they were an obvious "why are these here?" aspect that i was never really happy about, but figured it was some nunchuk unique requirement
gloomy shuttle
I still think you may want to avoid calling the read_data more than once in a single loop. It takes about .016 seconds per read.

I haven't found anything related to that... it would be interesting to see how mesh would handle cross-platform.
broken coyote
that's exactly my hope - the lightbulb espressif make is cheap and really well done - but it is a self contained unit as you'd expect (running on mains power directly). ergo, no serial cable to debug and hence no easy way for me to use something other than their firmware on it. my desire is to use those bulbs as shipped, but interact with them entirely within the CP and 'stock' esp32 boards
i have no experience using C with python or i'd be happy to do the work 'on my dime' and then contribute it back
broken coyote
@analog bridge exactly as you state above, the button pcb reference design is meant to be run with battery. the PITA however for developers, which they seem to have missed, is that if you use that image with a usb connection (so you can have a serial console) it thinks you are exclusively in setup mode and prevents you trying to test the buttons. you end up in a catch 22 - which is what led me here - how can i stop using my 30 year old C skills and get even rudimentary access to their mesh network - just to turn the darn light on and off...

@marble hornet 56kB is used for BLE-related storage by the SoftDevice (nrf firmware). 8kB is used for an SPI buffer to work around a hw issue. So ~150kB sounds right. I just checked on one.

umbral dagger
It's for a forum question relating to optimizing memory use
mem_free before/after I suppose.. but that's not necessarily the object of interest.
tulip sleet
the minimum object size is 16 bytes, and they are allocated in multiples of that. But integers and floats, etc. are 4 bytes because of their encoding.

Hmm.,. for example I add an int to a list and 240 bytes are consumed.
tulip sleet
a list has a minimum size and has room to grow
umbral dagger
rather mem_free and mem_alloc change by that much

@onyx hinge That's the only bit I'm still excited about
thorny jay
Are those PIO used for RAM to pin signal only (screen, Neopixel, ...) or can they do pin to RAM and pin to pin?
onyx hinge
@thorny jay I don't want to risk incorrectly summarizing PIO to you so I suggest you check out chapter 3 of https://datasheets.raspberrypi.org/rp2040/rp2040_datasheet.pdf

@slender iron good grief, #3911 is still failing on xtensa build due to bad build cache. If yours builds, I will merge it and then re-run #3911.
slender iron

The PIO state machines can shift data in as well
and ya, you could theoretically DMA from one SM to another
onyx hinge
the PIO neopixel example seems to be adapted from 3.6.2 if you want more explanation of what's happening.. https://github.com/adafruit/Adafruit_CircuitPython_PIOASM/blob/main/examples/pioasm_neopixel.py
Although not designed for computation, PIO is quite likely Turing-complete, and it is conjectured that it could run DOOM,given a sufficiently high clock speed
…
A full 32-bit addition takes only around one minute at 125 MHz
thorny jay
So CP compile from Python bytecode for VM and that VM run on the MCU. Then in Python there is an assembler that produce the code for that PIO statemachine? Maybe I need to take a break and let my brain sleep before it blow up.
tulip sleet
pio "programs" are loaded dynamically; they don't need to be part of the CPy firmware
slender iron
So CP compile from Python bytecode for VM and that VM run on the MCU. Then in Py...
basically yes
tulip sleet
some we can build in advance, like NeoPixel
slender iron
PIO programs are very small. at most 32 instructions
and that 32 instruction space is shared between 4 state machines
individual instructions are pretty powerful though
blissful pollen
That's pretty wild, can't wait to check it out

Can it pull in replacement instructions from memory, i.e. self-modifyin code?

@simple pulsar it can run instructions out of the fifo but not store to the instruction memory

we need to change how Mu detects a CP board
and really 🏃
tulip sleet
it was changed to just use the VID, I thought
simple pulsar
Can Mu deal with multiple boards plugged in at the same time? (I only use it occasionally.)
tulip sleet
some people rename their CIRCUITPY drives to accomplish that. I don't the serial console does
crimson ferry
@simple pulsar the serial/plotter will get confused
also, depending on your platform possibly, it may get hard to tell which Mu tab belongs with which device
thorny jay
@split ocean frequently has difficulties because he use CP to run some controller for his camera and also want to demonstrate CP. There must be ways and trick to deal with that. Typically, my PyRuler, if I want to use it "permanently" and work on another board... I need a kind of feature to make the PyRuler not be detected as a CP board. I would love to know the trick. Some requested to have a way to disable the CP drive.
thorny jay
That would be great. When I think about my uDraw tablet to mouse... it's almost like a product, I want it to be a mouse and forget it is a QT-Py and that I could change the behaviour just by editing a file.

@onyx hinge SAMD51 has setting on its DAC where it can hold the output or not. Otherwise it starts drifiting down. Maybe there is similar on the ESP??
the default was not to hold, which was confusing
jaunty juniper
I think it would be kind of cool to change whether the drive is enabled or not (or other things) from the UF2 bootloader, but not like by droping a different build onto it, but with some small configuration file thingy
maybe have a UF2 that writes to just a few dedicated bits if that's a thing
jaunty juniper
the idea being that by using the bootloader, it's always recoverable
tulip sleet
yes, right now I just load a "regular" UF2 to edit
onyx hinge
a safe-mode boot would bypass such settings
pretty sure safe mode skips boot.py altogether
jaunty juniper

I don't have it anymore but I soldered up an 8bit DAC to a parallel power in my youth to play mod tracker files on a PC. Probably better than Espressif's efforts

jaunty juniper
in my opinion Mu needs a simple little serial ports menu to override the default auto detection when it fails or gets it wrong, but I made myself a python script that does it's best effort to detect boards, their name, associated serial ports and drives like I wish already existed, I wonder if building a library for that would be interesting for anyone else (there's still work to do, turns out it's very os-dependent)
like, it gives you that:

I need some pointers on pointers!
I'm trying to add the ParallelBus for the ESP32-S2. I need to write an 8-bit integer into the GPIO output register (32 bits). Following the other incarnations of ParallelBus, I take the GPIO output registers (g->out) and create a uint8_t pointer into it at the right location for the correct pins (self->bus).
The trouble I'm having is that I can't seem to write using the uint8_t pointer (self->bus).
Here's my trial code:
gpio_dev_t *g = &GPIO; /* this is the GPIO registers, see "extern gpio_dev_t GPIO" from file:gpio_struct.h */
self->bus = ( (uint8_t*) &g->out ); //pointer to GPIO output register (pins 0-31)
mp_printf(&mp_plat_print, "\n\nPointer addresses:\n");
mp_printf(&mp_plat_print, "&g->out: %x\n", &g->out);
mp_printf(&mp_plat_print, "self->bus: %x\n\n", self->bus);
mp_printf(&mp_plat_print, "Writing zeros to parallel output\n");
g->out = 0x0000;
mp_printf(&mp_plat_print, "Current output g->out: %x\n", g->out);
mp_printf(&mp_plat_print, "Current output *self->bus: %x\n\n", *self->bus);
mp_printf(&mp_plat_print, "Writing ones to parallel output\n");
g->out = 0xffff;
mp_printf(&mp_plat_print, "Current output g->out: %x\n", g->out);
mp_printf(&mp_plat_print, "Current output *self->bus: %x\n\n", *self->bus);
Here's the output:
Pointer addresses:
&g->out: 3f404004
self->bus: 3f404004
Writing zeros to parallel output
Current output g->out: 0
Current output *self->bus: 5a
Writing ones to parallel output
Current output g->out: ffff
Current output *self->bus: 5a
The GPIO pointer is uint32_t (g->out) seems to write zeros and ones just fine. But somehow when I try to use the uint8_t (*self->bus) to read it, it seems to be pointing somewhere else. I thought \*self->bus should return ff but it returns 5a (I assume some random value in memory).
I think this may be something to do with the 32bit vs 8bit but I can't figure it out. Anybody can "point" me in the right direction?
slender iron
@mental nexus you can also print the pointer itself with %p in printf
you can use that to confirm you are dereferencing the right location
tulip sleet
I would double-check the operator precedences
add parentheses to make sure
but I think those are ok

hey all, wondering about how the RPi pico works with the official micropython and circuitpython.
for the official micropython, do you download the UF2 file and drag a .py file with code onto a mass storage device to run? and the same with circuitpython, i assume that's how that's working too? just a bit of confusion on my end.
tidal kiln
@gilded cradle cool. thanks. yep. will do. i'll respond in pr thread.

@slender iron @tulip sleet ok I will take another look. I thought maybe I have a big/little endian confusion but I can’t trace it. I’ll try your debug tips and see if I can track it down.
slender iron
@zinc maple for official micropython you have to use Thonny to load code. They don't have the device show as a mass storage device (and use non-FAT filesystem internally)
CircuitPython acts as mass storage and stores files to FAT
basically works like all CircuitPython boards

tidal kiln
@gloomy shuttle @thorny jay I've been playing with Nunchuk code with delays completely removed from the I2C read and it seems to be working very reliably. The only thing I can think that made this not work before was that the I2C bus may have been clocked at 400kHz instead of 100kHz. At 100kHz, it seems pretty solid. The removal of these delays essentially negates the need for any fancy buffering or special reading. Please try the version of the library code here
https://github.com/caternuson/Adafruit_CircuitPython_Nunchuk/blob/speedup/adafruit_nunchuk.py
and see if that performs OK with current Nunchuk examples - with no other changes to the example code. Hopefully it's just fast now. And make sure whatever host you are using has I2C SCL set to 100kHz. It defaulted to 400kHz in some older firmware and maybe even library code.
thorny jay
I am not sure about the course of action: (1) fix the mouse hid (2) make the above the new version (3) change to module (4) add other device with simpletest. And most importantly who does what step and what device.
We have many cancelled PR and WIP.
tidal kiln
(2) and (3) sound like same thing? basically update library to something like that and (1) is just fixed.
(4) comes later
i can PR the suggested change, but was hoping you could also help test if you wanted to - for the nunchuk case
thorny jay
(3) is a folder with or without _ _ init _ _
tidal kiln
oh, is see. ok (3) comes later also.
thorny jay
I can test the new Nunchuck, but all the version I tested worked.
(5) rename to match (4)
tidal kiln
this should hopefully work with the current analog mouse code though
some of the other approaches required new code for that example
thorny jay
I try tomorrow (1 AM here).
tidal kiln

I will test the nunchuk version you just linked to tonight. I have something form 8:00 to ~9:00 pm est, so I'm not sure if I will get it tested before that.
manic glacierBOT
gloomy shuttle
@tidal kiln this version switches to the values approach which shouldn't change anything for testing, but are you planning on implementing it this way? Also, there is another potential sleep that could be removed in the __init__ method.
tidal kiln
i might change that in the final version. it would be functionally equivalent though. i'd probably remove values and move code back into each property.
yep, i saw that delay in __init__ also. that one's less annoying since it's just run on once. but i do want to look at that also and see if can get removed as well.
and no real need to hurry on the testing. just as you can. and then can ping me back here whenevs.
gloomy shuttle
I agree with all of the above. I didn't need it during my testing yesterday.

i really wish i knew why that didn't work before. the SCL freq is just a guess. may never know.

I figured out how we can get searching of code working in the CP Repo...
https://docs.github.com/en/github/searching-for-information-on-github/searching-in-forks
"Forks are only indexed for code search when they have more stars than the parent repository. You will not be able to search the code in a fork that has less stars than its parent. To show forks with more stars than the parent repository in code search results, add fork:true or fork:only to your query."
We need about 10,000 people to star the CP Repo for that to be true.
https://github.com/adafruit/circuitpython
slender iron
there is a code search sort of service that notro setup at one point
we could run one separately

I like the idea of 10,000 new stars. But yes. I mean I could search my filesystem too...

we'll get there 🙂
idle wharf
Someone run serverinfo.... CP has 2k stars... so I think about 24,000 people could help 😉

Regarding my pointer issue, I'm unsure if the ESP32-S2 will allow non-aligned access. There's a note here in section 10.3.3 of the ref manual:
I'm trying to access address 0x3F404004, right in the middle of this section that may cause an interrupt or exception.
Also, there seems to be a related issue here: https://github.com/espressif/esp-idf/issues/597
I posted a question about this on the ESP discord. I'll report back here if I get any good leads or clarification. In light of this stumbling block on single byte writes to the GPIO registers, I’ll craft a version with full 32-bit writes as a starting point for ParallelBus.

@tidal kiln it runs great on the QT Py, but not so well on the featherS2. I tested all the examples on the QT Py. I used the nunchuk_analog_mouse.py on both the QT Py and the feathers2. The QT Py averaged .0079 seconds per loop while the feathers2 averaged .059 seconds per loop. I know there have been some reported issues on the feathers2 with I2C, so that may be the issue - https://github.com/adafruit/circuitpython/issues/3894

Which FP libraries does CircuitPython use? I'd see the talk about "optimised libraries [for M0] in rom" for that new RP2040 Pico board but wasn't sure what they were referring to. According to an EEVblog forum post they are related to https://www.quinapalus.com/qfplib.html
simple pulsar
No, I haven't compared them. My plan is to move to the PPK2 simply because it's ...
The DevZone discussion indirectly raises the question of whether a (second-hand) version of the previous version or waiting for a "PPK2.1" would be better. I've just got some traction with Nordic via YouTube interaction so hopefully they'll be some clarity on the PPK2 behaviour.
