Hello, We have a problem with creating a 2nd UART. The first UART is low speed, and we want to make a second UART with

--baud_rate=2_500_000

from the

toit-pixel-strip

package. We get the following error when creating the driver:

followed by ALREADY_IN_USE everytime it is called. The

After reading the docs at https://docs.toit.io/language/strings I don't understand the way to do string contains. In Python:

if "foo" in "foobar":
    print("String was contained")

Ruby:

if my_string.include? "foo"

Is there a way to check to see if a string contains a substring?

import ble

DEV_NAME  ::= "O2Ring"
SCAN_DURATION   ::= Duration --s=3

find_by_name central/ble.Central name/string:
  central.scan --duration=SCAN_DURATION: | device/ble.RemoteScannedDevice |
    if device.data.name and device.data.name.contains name:
        return device.address
  throw "no ring device found"

main:
  adapter := ble.Adapter
  central := adapter.central

  address := find_by_name central DEV_NAME
  remote_device := central.connect address
  print remote_device.address

I'm trying to communicate with a ring-based pulse oximeter which does not advertise any services. when calling

discover_services

I receive a NimBLE timeout error. I know the service UUID, and the UUID of the characteristics I'm interested in. Can I skip straight to exchanging write/notify data from the characteristics? Service data from LightBlue screenshots are attached

Following the tutorial from https://github.com/toitlang/jaguar on a mac. I can run jag monitor, and then jag run hello.toit on the simple Hello World program. When I

jag run hello.toit

the monitor spits out Hello World! as expected. When I run

jag watch hello.toit

the monitor spits out Hello World! but then any writes to the file after that does not do anything. I have tried appending to the file on cli using echo, vim and text edit

Hello, I'm trying to follow the " Quick Start Guide" in the Toit docs. I install as instructed for windows: winget install --id=Toit.Jaguar -e it runs telling me it found Jaguar [Toit.Jaguar] Version 1.8.1 it then downloads it and says the package was successfully installed. The problem starts when I try to type any jag command. I get back 'jag' is not recognized as an internal or external command, operable program or batch file. I have tried this on two separate windows machines but get the same issue. Does anyone know what I could be doing wrong?

is it still possible to provision using the console at console.toit.io? I used to have no issues provisioning, now none of my boards will provision there.

I flashed my ESP32 through the jaguar cli and now it is not being claimed in the console. The claiming process uses toit command though. I followed all the steps but the toit command does not seem to be working, the jeg command does. Do I have to add toit to my PATH manually? thanks

I've moved my ESP32 to a different position and I need to reconfigure the wifi SSID and Password. However I do not want to re-flash. Is there a way to do this over serial by any chance? Thanks.

Is there anyway to pass login-information to the "toit auth" command, instead of having to login using the web-browser?

After my device receives a "DEADLINE_EXCEEDED" error, the device gets stuck in this "DEBUG: Attempting to (re)connect" loop. It won't even reboot. It is set up with an MQTT-connection, and I think this somehow is the cause. How can I fix this?

Question for @MikkelD -- I'm trying to interact with a button via BLE, but I must be missing something. I've tried this both with an "AB Shutter3" button, and a "VR-PARK" joystick. I scan, discover, and connect to the device. Then I retrieve the relevant service, and the characteristic.The properties are 18 and 26 respectively, ie they support notifications. I subscribe to the characteristic, and then

wait_for_notification

on it. This blocks, and nothing happens, even if I press the button(s) to create events. (Actually, even reading out the characteristic without bothering with the notification doesn't yield any changed values). Any idea what I'm missing? For the VR-PARK, there is some sample code which I'm trying to replicate: https://github.com/BigJBehr/ESP32-Bluetooth-BLE-Remote-Control/blob/master/BLE-VRBOX.ino

Hello! I have an ESP32-LyraT v4.3 development board which has a ESP32-WROVER-E and ES8388 codec chip on-board. I am trying to get audio from the AUX_IN to the PHONEJACK. Using the I2S library, I'm trying to do basic reads/writes to/from an I2S bus but I guess I am missing something, because I only seem to be able to read 0x00 out of the bus. Here's what I have so far:

import i2s
import gpio

SCLK ::= gpio.Pin 5
LRCK ::= gpio.Pin 25
DSDIN ::= gpio.Pin 26
ASDOUT ::= gpio.Pin 35

main:
    // Initialize I2S bus

    bus := i2s.Bus --sck=SCLK --ws=LRCK --tx=DSDIN --rx=ASDOUT --sample_rate=44100 --bits_per_sample=16 --buffer_size=32
    i := 255

    while i-- > 0:
        bytes := bus.read
        print "Writing $(bytes.size) bytes"
        print "$bytes"
        bus.write bytes

Any advice would be much appreciated!

Values stored in RAM are retained between reboots, so long as power is maintained, right? I have tried this code on two ezsbc ESP32 boards with fully charged LiPo's and JAG monitoring via USB. If I use --flash, the storage count increases. I I use --ram, the storage count is always 1, nothing is retained after deep-sleep. Using JAG v1.9.1, I just can't see what I am doing wrong.

import esp32
import system.storage as storage


// RAM_STORE_       ::= storage.Bucket.open --flash   "/admin"
RAM_STORE_       ::= storage.Bucket.open --ram   "/admin"


main:

  RAMBuffer.add Time.now.s_since_epoch

  print "size after $RAMBuffer.size"

  esp32.deep_sleep (Duration --s=5)


class RAMBuffer:

  static exists -> bool:
    return null != (RAM_STORE_.get "buffer")

  static get_buff_ -> List:
    buffer := RAM_STORE_.get "buffer"
    if not buffer: buffer = []
    return buffer

  static add entry/any -> none:
    buffer := List.from get_buff_
    buffer.add entry
    RAM_STORE_["buffer"] = buffer

  static clear -> none:
    RAM_STORE_["buffer"] = []

  static size -> int:
    return get_buff_.size

  static remove_first -> any:
    buffer := get_buff_
    entry := buffer.first
    RAM_STORE_["buffer"] = buffer[1..]
    return entry

Hi, I'm trying to store some data on an SD Card. I have found the flash library, which provides

Mount

, which allows me to mount (and format, if necessary) an SD Card. But how do I read and write with it? Are there any examples that I could use as a starting off point?

I'm trying out the example code from the

Touch

class, but I'm getting an error when trying to run it:

******************************************************************************

  2: main                      touch-test.toit:21:18
******************************************************************************

The code I'm using is

while true:
    touch := Touch (gpio.Pin 0) --threshold=500
    print (touch.read --raw)
    touch.close
    sleep --ms=1000

(plus the relevant imports). I'm using a TTGO T-BEAM, and pins 0 or 32 bothe didn't work... Any ideas?

Hey im pretty new to Toit and Jag, but i would love some help. Im trying to connect to a mqtt brokker but when im trying to use the libary mqtt and follow the guides i keep getting errors with anything that relates to the mqtt. Im programming on the web console from toit.

Is there any documentation about how to use the various classes from the

monitor

package? Like Gate, Mailbox, etc?

Hi there, thanks in advance for any help I need to run some tests to evaluate the LoRa protocol, and i have been checking a bit on Toit language and i see it would be great to use it on the project. I dont see at a first glance any device ESP32 based that could be used, to run Toit on it and also with LoRa capabilities, is this possible? can you suggest any PCB that could be used for this purpose? On the other hand, i have some TTGO boards that implement LoRa and even are based on ESP32, i guess i cant run Toit over this kind of boards, this correct? Thank you, looking forward to an answer.. cheers

The defaul argument for

max_files

for formatting SD cards is 5; is that not a bit small? What exactly is the meaning of that value?

Hello, I noticed some varying Ota speeds on our toit devices, and decided to investigate the problem. The speeds would vary from 40 seconds to over 3 minutes. After i cleaned the SD card on the slow devices, it brought the time down to like 40 seconds. I made some tests with the SD-card, by making big files and many files to see the impact on the Ota speed. The files I made are in a folder being used by the device. I tried putting the files outside the working folder, but that did not change the Ota speed. In conclusion: The amount of files present in a working folder slows down the device. I have trouble finding out why this is the case. - We are appending to a single file 0-3 times a second - SPI clock is at 400 kHz - The

host

package is used to create a file stream to the 1 file - The Ota data is received with http client - Ota data is written with

firmware.FirmwareWriter

writer

can I still sign up online account? Went to the toit.io, can not find anything for opening a new account

Hello. I've updated to alpha 63 from alpha 47, but I have problems with OTA now. It looks like the esp32 completly freezes after writing ~350-400 times with the

FirmwareWriter

. The OTA process is spawned, but everything freezes when writing with

FirmwareWriter

. I will provide more details soon

I am trying to write code to get the acceleration values from MPU 6050, the code in arduino for this is:

#include<Wire.h>
const int MPU = 0x68;
float AccX, AccY, AccZ;

void setup() {
  Serial.begin(9600);

  Wire.begin();
  Wire.beginTransmission(MPU);
  Wire.write(0x6B);
  Wire.write(0);
  Wire.endTransmission(true);


  Wire.beginTransmission(MPU);
  Wire.write(0x1C);
  Wire.write(0b00011000);  //scale factor +/-16g
  Wire.endTransmission();
}
loop(){
  Wire.beginTransmission(MPU);
  Wire.write(0x3B);
  Wire.endTransmission(false);
  Wire.requestFrom(MPU, 14, true); // Solicita os dados ao sensor

 AccX = Wire.read() << 8 | Wire.read(); //0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)

 Serial.print(AccX / 2048);
 Serial.print(" ");
 Serial.print(AccY / 2048);
 Serial.print(" ");
 Serial.println(AccZ / 2048);
}

i have already started making the porting to toit, and i am stuck in this:

import gpio

    device := bus.device MPU9250_ADDRESS

can any one help me to finish this code in toit?

hi toit is really great! I'm having fun with it on multiple devices. It was no problem to get into it all. But I have problem to create a new driver for the Ina219 i2c sensor. I use other i2c drivers as blueprints. I get an I2C_READ_FAILED when I try to read the chip id.
