Pixelstrip on ESP32S3

woody

02/23/2025, 11:02 AM

Hi, I got the ESP32-S3-DevKitC-1 and flashed it with

Copy code

jag flash esp32s3-spiram-octo

, I'm using SDK version: v2.0.0-alpha.174. I tried to get the RGB LED running with this program:

Copy code

import pixel-strip
import gpio

main:
  rgb-pin := gpio.Pin 38 --output=true
//  while true:
//    // sleep --ms=0 => 40 µs
//    // sleep --ms=1..9 => 10ms
//    // sleep --ms=10..x => 20ms..10+x
//    rgb-pin.set 1
//    sleep --ms=1
//    rgb-pin.set 0
//    sleep --ms=1

  rgb := pixel-strip.PixelStrip.uart 1 --pin=rgb-pin --invert-pin=false
  while true:
    rgb.output #[0xff] #[0xff] #[0xff]
    print "white"
    sleep --ms=1000
    rgb.output #[0xff] #[0] #[0]
    print "red"
    sleep --ms=1000
    rgb.output #[0] #[0xff] #[0]
    print "green"
    sleep --ms=1000
    rgb.output #[0] #[0] #[0xff]
    print "blue"
    sleep --ms=1000

Program compiled and downloaded fine, but on the LED nothing happened. I measured Pin 38 with an Oscilloscope an it stay permanently low. What do I miss in my program? Or is the package buggy?

Waiting for a list of tasks

Wifi Access Point - Auth Mode

crockedile

03/10/2025, 12:37 PM

Currently working on a project that involves using the the esp32 as a wifi access point with a captive portal. I have everything working at this point, but would like to be establishing an open network if possible, rather than one requiring a password: "wifi.establish --name="espfi" --ssid="espfi" --password="password" --broadcast=true" Per error codes, it seems the code above requires the "--password" argument. Is there a way around this? I tried --password=NULL, --password="" and even attempted --authmode="open" hoping it was undocumented. No luck.

too many DHTXX devices ?

kaxori

03/14/2025, 11:06 AM

For plant cultivation, I would like to use several DHTxx sensors to check the favorable germination environment. The prototype uses an ESP32 'wroom'. Four sensors can be configured in the application. An exception error is generated when initializing the fifth sensor:

Copy code

EXCEPTION error.
ALREADY_IN_USE
   0: gpio-use_                 <sdk>\gpio\gpio.toit:855:5

The Toit DHTxx package uses RMT-devices. ESP32 shout provide 8 RMT channels. Is it possible to use more than 4 devices on an ESP32-Wroom ?

jag flash raises EXCEPTION error.ILLEGAL_UTF_8

Hi, I am running into the above issue when running jag flash build/esp32c6/toit-firmware.bin --chip esp32c6. it works with idf.py flash though when running jag monitor afterwards the device doesn't connect to network

Is there a way to build / flash, while ignoring code sections

addshore

03/18/2025, 10:11 AM

I c++ I can do something like

Copy code

#ifdef FOO_BAR
    doStuff();
#endif

Is there a similar way to do this sort of thing with toit? The primary usecase for me would be to entirely avoid building verbose log lines, which in their call might create long strings etc, when there is no expectaiton for that log line to every be used? The only alternative right now I guess would be commenting and un commenting lines continually?

I2S on 2.0.0-alpha.175 causing panic

Rikke

03/18/2025, 11:20 AM

I have updated my toit sdk to 175, and I have changed the use of I2S to match the new syntax:

i2s_bus = i2s.Bus --tx=pin --sample_rate=100_000 --bits_per_sample=32 --buffer_size=(buf.size + reset.size) --use-apll=false

Copy code

i2s_bus = i2s.Bus
      --master=true
      --mclk=null
      --tx=pin
      --sck=null
      --ws=null

    i2s_bus.configure
      --sample_rate=100_000 
      --bits_per_sample=32 

    i2s_bus.start

But in 1 out of 20 reboots(ish) I get a panic when starting up the i2s:

DS3231 driver and package registry

pkarsy

03/30/2025, 6:17 PM

Hi I have recently found about toit and as I am working (as a hobbyist) on a project using the DS3231 real time clock I decided to create a driver for it. The driver has the github page https://github.com/pkarsy/toit-ds3231 Although with very limited testing, seems to work OK. The problems started when I tried to register the project to https://pkg.toit.io The name of the project was "ds3231-toit" (github name) and I registered the version v0.8.0 After reading a recommendation in the documentation, I renamed it to "toit-ds3231" (a bad idea it seems) Unfortunatelly now there are 2 ds3231 drivers appearing as separate projects in the package registry The old one of course is absolete and it should be removed How can I do this ? Also there are some revisions in the new driver I rather delete. I am not familiar with releases and semantic versioning and I messed up the release. Is there any way to delete some specific version ? Thank you in advance Panagiotis PS. The language is fantastic ! I never had any expectation such a good option will ever exist for embedded programming. This includes the very good syntax the jag and artemis tools and of course the VS-code plugin

I imagine the answer is either https://github.com/toitlang/envelopes or https://github.com/toitlang/template-custom-envelope I want to maintain a repo that will / can contain multiple envelopes / fw builds for use by us (containing a selection of pre installed containers) As far as I can tell template-custom-envelope is primarily setup for a single envelope For multiple, am I better of replicating the main envelopes repo?

However this isn't possible in toit, what would the closest thing be? Or is there an example of fluid / chained function calls

How to accurately capture fan speed (TAC Pin) on ESP32?

Arubinu

04/25/2025, 7:29 PM

Hello, I would like to measure the speed of my fan (12V) using the TAC pin. On ATmega microcontrollers, if I'm not mistaken, there's ISR support (interrupt service routine) that allows you to catch each pulse. What would be the equivalent approach on Toit.io for ESP32 devices? When I simply create a task with

(gpio.Pin MY_PIN).do:

, I don't get reliable results. But I suspect the issue comes from how

.do:

behaves inside a task, since it appears to be blocking...

Captive Portal + Artemis

bpmct

05/03/2025, 10:48 PM

I am hoping to run a fleet of devices that I can hand to friends and they can initialize on their own wifi after plugging in via a captive portal. From there, I'd love to push updates. Architectually, I'm still getting my footing here so I was wondering if anybody had any pointers on whether this is possible today/things to look our for or any recommendations on how to do this... I am assuming I could register it on my WiFi, and then have some "fallback" captive portal if the connection fails... seems the safest because it'd also allow people to move their devices but unsure what this means in practice or whether artemis supports this

Artemis - REST API & Offline Devices

bpmct

05/05/2025, 9:34 PM

I am interested in allowing devices to be offline for a large amount of time (e.g. hours, days, months) but when plugged in, they re-join the fleet and may even fetch OTA updates. I also want to be able to programmatically query an API to understand which devices are offline or offline? For the offline length, it seems like I just need to set

max-offline

to a very long number. However, I'm not sure if artemis has the built-in capability to query whether something is on or off, besides looking at

events

. Is there a REST API I should be programmatically querying, or should I be sending health to artemis via events, or using an external backend to keep track of devices and health? Thanks!
