@kuriko Why are there 2 UIFlows?
What is the difference between UIFlow1 and UIFLow2?
I see the occasional reference of UIFlow3?

@Bipman What sensor are you trying?

@leo-ninja-turtle said in Unable to burn firmware for Core device:
Not sure what you mean by:

it came originally from the factory with UIFlow

@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.

@PhilB79 Can you upload a small Arduino IDE test file?
Like a generic serial monitor test?

@brrainz Which part number such as "U016" do you have?
There are several 'M5 Thermal (MLX90640)'

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:

(Stamp-PICO require a separate Programmer.)

Also suggest The StampS3 (with built-in USB):
https://shop.m5stack.com/products/m5stamp-esp32s3-module

and the new very small mini OLED product.
https://shop.m5stack.com/products/mini-oled-unit-0-42-72x40-display

It 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!)

@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))

@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:

@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?

@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.

@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.

@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)

@leaguen How do you power the Stamp now? If you input 5V to either 5V pin, the Stamp will get 3.3V and the other pin will be 5V.
The Docs are here:
https://docs.m5stack.com/en/core/stamp_pico
What sensor needs 5V? (just curious as I am almost exclusively 3.3V now)

@leaguen OK! Curious thing about the Stamp pico is that 3.3V in from the programmer device is all that is available at the ""5V"" pins!

There is no Boost regulator on this one.

@leaguen You can solder directly to the Stamp Pico or install a Grove connector, I think it came with one?

@leaguen What stamp? Do you mean the USB?

@leaguen You can solder a grove connector to the side of the Stamp and get Gnd, 5V, and two GPIO that can be used for I2C sensors.
