@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:
https://shop.m5stack.com/products/m5stamp-pico-mate-with-pin-headers

and the new very small mini OLED product.

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:
https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Application/Bala2

@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.

@ddhard Sounds good!

@geanner OK! Good detective work!
Keep us posted.

@Jonny-Spaceman No.
The sketch that I posted takes 20 seconds to compile and less that 15 seconds to upload. Apple M1 Mac.
It is a generic test program I wrote for this reason and to help debug Serial.print problems.
I suggest trying my diag sketch to test your environment.
VS Code will not help compile this sketch any faster.
The sketch that takes Tea Time is then the problem.

If you tell me what M5Stack device you are using and the exact code, I will try it here.

@Jonny-Spaceman Yes.
Just kidding.
What M5Stack do you have?
Are you using Arduino IDE ver2.3.2? It is very stable for last three or four months.
Try a simple sketch. Copy this sketch to a 'New Sketch', over writing the standard framework.

https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples/blob/main/Generic_tick_tock_serial_test/Generic_tick_tock_serial_test.ino

Try the standard upload speed 921600.
Try a slower speed and double check that your USB cable is a communication cable, not just USB charge.

A small sketch should take 15-20 seconds to compile and 15 to upload to the board.

@YigalB Two Joysticks would require a PaHub accessory from M5Stack:
https://shop.m5stack.com/products/i2c-hub-1-to-6-expansion-unit-pca9548apw
These work very well, seamlessly.
I don't know how to change the I2C address of the Joystick in this register, sorry.

@YigalB I2C is correct.
Here is the example:
https://github.com/m5stack/M5Unit-Joystick2/blob/main/examples/get_value/get_value.ino
The internal firmware is already installed and like most M5Stack Units it is 'permanent' and does not require your attention but could theoretically be updated in the future.
