@nefasto which end of the cable did you plug into the port?
IN or OUT?

RE: Python development in UIFlow
@sternj Well, the Arduino IDE ver2 IDE is very good.
Just type in C, C++ and download (it compiles automatically.)
This is NOT your grandad's Arduino IDE ver 1 !!!
Here is a sample program to test serial:bool ticktock; //declare ticktock as a boolean flag void setup() { //runs once on start up Serial.begin(115200); //open the serial port for USB cable delay(500); } void loop() { //runs in circles! ticktock = !ticktock; //every pass through reverse the flag if (ticktock) { //test current value of the ticktock flag Serial.println("tick"); } else { //prints one or the other to the USB port Serial.println("tock"); } delay(1000); //wait for a second and run again! }

RE: Python development in UIFlow
@sternj Hi!
You sound like you are too advanced for drag and drop.
I think you should stick to micropython for its range and flexibility.
Cheers. -
RE: Env Pro (BME688)
@dnd3ch Most Unit style sensors have a compatibility section, down at the bottom of the sensor's document page:
https://docs.m5stack.com/en/unit/DLight Unit
Go down to the FAQ section near the bottom.Having said that:
All of the unit sensors will work with any M5Stack controller.
The Dial is just a StampS3 for example.The M5 core bases are another story and require research or asking here if they are compatible.

RE: myCobot 320 UIFlow comunication problems
@kuriko Why are there 2 UIFlows?
What is the difference between UIFlow1 and UIFLow2?
I see the occasional reference of UIFlow3? -

Not sure what you mean by:it came originally from the factory with UIFlow

RE: Getting started advice needed
@ivanurwin The ESP32 S3 series is difficult to get into Download Mode. Once you learn the trick it is not too difficult.
They work fine in Arduino IDE , once you get it into Download Mode.
Also check your cable, it may be only a charging cable with no comm capabilities.
It can also be a driver issue, be sure you have the correct USB driver in your PC. -
RE: M5CoreS3: "ERROR Device type unknown" when trying to connect both CoreS3 and CoreS3 SE to Server.
@PhilB79 Can you upload a small Arduino IDE test file?
Like a generic serial monitor test? -
RE: Atom S3 Lite + M5 Thermal (MLX90640) Code Example?
@brrainz Which part number such as "U016" do you have?
There are several 'M5 Thermal (MLX90640)' -
Ported my 'Check Modem' sketch to all M5Stack products
Not sure 'Who Cares' but The Internet, especially on WiFi, has been flakey recently.
I made a Arduino sketch for the StampS3 and an aftermarket OLED last week.
So I ported it over to a Stamp-PICO:
https://shop.m5stack.com/products/m5stamp-pico-mate-with-pin-headers
(Stamp-PICO require a separate Programmer.)Also suggest The StampS3 (with built-in USB):
https://shop.m5stack.com/products/m5stamp-esp32s3-moduleand the new very small mini OLED product.
https://shop.m5stack.com/products/mini-oled-unit-0-42-72x40-displayIt is my first Dual Core sketch and I am now hooked.
It also made the porting much easier, just changed the graphics in the Core1 and left Core0 with the WiFi and Net tests unmodified.(that is a Canadian Nickel 5cent piece!)

RE: REQUEST FAILED CREATE NEW PROJECT
@Rango We are experiencing Internet outages here in Canada in the last few days due to Solar Flares. On and off, some sites worse than others and I think some parts of the world experience it differently.
Had 'Interac' difficulties trying to pay for gas!
This may be what you are experiencing.
(Ironically I am working on a WiFi and Internet Trouble detecting, cute little device, based on a Stamps3 and a matching sized uOLED (from Sparkfun)) -
RE: How to extract the current Flash and EEPROM data from M5Stack fire to Windows11 file ?
@RuriObb You cannot extract the source code from an ESP32 except a raw bin file.
But this is the example Arduino IDE source code (C, C++) on Github:

RE: thermometer with a 1-wire probe
@ddhard Sounds like a great starter project, good luck!
Are you planning on using Python, UIFlow or Arduino IDE ?
Plenty of good IOT examples on The Internet.
What controller?

RE: Need Module with I/O for connections...
@SirMichael They core basic has a lot of pins in the battery base, did you look at it? (about 15 GPIO)
https://docs.m5stack.com/en/core/basic_v2.7
Also you may can add the PaHub or PbHub to expand.

RE: Power needed
@leaguen said in Power needed:
The HC-SR501 is an old Arduino era sensor designed for 5V. Many people use it with an ESP32 3.3V with success.
But yeah, putting 5V to either 5V pin will power the ESP32 @ 3.3V and 3.3V will appear at the side 3.3V pin. And 5V will appear on the Grove 5V pin.
Very clever design. -
RE: Power needed
@leaguen Great, so you are supplying it with 3.3V.
If you supply 5V through the 5V connector on the left side, 5V will also be at the bottom 'Grove' connector...and the 5V will be stepped down to 3.3 for the Stamp ESP32 ckt...and 3.3 will be available at the 3.3v pin on the other side.
Win-win.
Do you have a part number for the IR sensor?
I would like to check it out, maybe runs on 3.3V? (Despite the rating)
