@kaidencoolkid tried to "erase" first? or try to install simple arduino sketch to it. Is com port detected by pc when Stic is connected to usb?

@mukul_100_ i would recommend to study some of YT VolosR examples of his approach to UI

open M5Burner, if you see comport detected when you connect M5Stick to usb then next step would be to burn CORRECT firmware to it as there are few versions for M5Stick

@nak750 said in Download shows 'Progress' but nothing happens:

Hi all, I am new to UIFlow and M5 Stack, I have done the Firmware flash using the M5Burner. Now using UIFlow, I can connect to the Serial Port, I can see the device sending default messages, then I press on Download, it shows 'Progress' but nothing happens. Can anyone please help?
I have tried the Download button on the right bottom of the UIFlow, this then shows Device Disconnected, but the webpage shows USB connected?

what M5Stack device do you have? some have to be in boot mode to allow programming, some accept new program straight away

@GreekAlex can you see comport being detected when you connecting usb in to it?

@MiguelM looks like rotation isnt right, what is displayed if you just burn easyLoader demo file or latest uiflow2 firmware from M5Burner?

@jorge5a using comms monitor in M5burner?

@Bzh2ant2 is M5burner detecting any comport while your device is connected to usb?

when you open M5burner and you connect USB to your M5StickC+2 can you see com port number popup in top right corner of M5burner?
if so then download latest firmware for your M5StickC+2, hit erase, then burn

@spectrad have you tried with the M5Stack example here?

he doesn't have M5Stack controller, only M5Stack sensor trying to read back to Arduino NANO so not esp32 board.

@spectrad said in AIN4-20mA Unit to Arduino Nano Every:

I am trying to talk to the module using a Nano Every using the standard wire example, I get no output at all. If I use a sniffing sketch, it detects the device on 0x55 so it is visible on the bus.

#include <Wire.h>

void setup() {
  Wire.begin(8);        // join i2c bus (address optional for master)
  Serial.begin(9600);  // start serial for output
}

void loop() {
  Wire.requestFrom(0x55, 8);    // request 8 bytes from slave device 0x55

  while (Wire.available()) { // slave may send less than requested
    char c = Wire.read(); // receive a byte as character
    Serial.print(c,DEC);         // print the character
  }

  delay(250);
}

I have a 4-20mA current source which I can measure, so I am confident I have a variable input.

I have not used I2C before, I am confident the Arduino libraries are correct, so any pointers to what it might be would be appreciated. Thanks.

not sure if you can marry M5stack sensor/module with diff MCUs than esp32? maybe I'm wrong here.

@guarthur said in Can't read ENV IV using UIFlow2:

I can't get my M5Stickplus2 to read any variables from my ENV IV. I've used the example and it doesn't work. Does anyone has a valid example that works? I'm wondering whether the ENVIV has a problem

have you tried EasyLoader file for ENV 4 unit?
have you tried Arduino example from ENV 4 documentation page? - Double check that I2C pins are correct

@mb check VolosR YT examples to his UI approach

@guarthur see below
sample from example and sample from uiflow

check that correct gpio is declared

@ioamas what is your code?

@gdbongle said in Writing serial output from sensor to USB stick connected by M5Stick's onboard USB-C port:

I'm trying to get data from a sensor connected to my M5Stick and put it in CSV format to be written to a USB stick for later processing (including timestamps) but I'm not sure where to begin, nor have I found anything of relevance on the forums/docs. Is there somewhere I can begin?

writing in to SD card would be one to start from I think

@ivosak when you left it connected to charger was on/off button in ON position?

@mb you can use hide/show/set based on condition for items on different screens,
I would recommend "VolosR" github/YT for UI design approach but this is arduino mostly, also there is block to run your code in blockly

@mb button, timer etc needs to be added in left hand menu below controller image "software/hardware" in manner you would add module or unit

@mb is device showing as connected still after first "run"? usually should be but if you use upload then wifi block should be included in the code so unit is connected to network, can you try same with uiflow2?
