I think M5Stack should consider rewards vouchers - like a 10%-15%-20% off discount code after someone spends $800 USD on products, or something like that :D

I wish there was a battery module for the AtomS3 , of the same size as the AtomS3, that fit on the back instead of how the TailBat attaches. So it would be more cubical. An AtomStack.

I know it would be smaller capacity. Maybe 24mm x 24mm but thicker than the AtomS3

@ajb2k3 Ive never spent that much at once.. no more than $200 USD per order, but Ive spent over $800 USD in the past month :/

Ive only really discovered the M5Stack ecosystem recently, and have become addicted. Initially I was dismayed by what seemed a lack of activity in the forum, but I now see it is a very lively, active community - but seemingly focused on twitter as the way to interact, rather than a forum?

Anyway, I am trying to compile a list of possible upcoming M5Stack products, as mentioned on tweets from @M5Stack on twitter, and just from the past few weeks, these have been mentioned:

Some sort of "M5Stack S3 Uno"? (M5Letter?)

Question: Is there another source of info about upcoming products, other than cryptic (to me) tweets? Any pre-release developer channels or beta/insider programs?

They added support for "ENV IV" in the latest UIFlow2 Alpha 23 - as if they expected it to be released at the same time, so... I am assuming it is going to be very soon. [Although Twitter/X mentions ENV "Pro" which looked Gray, not white.]

Im waiting for at least one of the following "soon" products to be available before my next big order:

MStickS3
M5NanoS3
M5Dial
AtomS3Echo
StampFly/StampS3FPV

Though I wish they would release them all at once, instead of one per week. Shipping to NZ has skyrocketed, so it would be helpful if they were all available so I could buy them all in one order :(

@bram Did you self-solder connectors and pins?

Ive seen this a few times with tiny solder bridges to vcc or gnd that varied when they heated up/cooled down and acted exactly that way. (Or similarly when I took too long soldering pins, and damaged an internal component from the heat of the pin/solder pad)

@robot_alf "need to connect sensors to 1,2,3 ports of pahub, not to 0,1,2"

There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors :D

@ajb2k3

When I add the ENVIII unit to my CoreS3 on port A, and start it, I get the exception at line 98 of qmp6988.py (the call of reset() )

The issue seems to have been noticed and fixed 8 months ago though, by some guy named Gandro:

https://github.com/gandro/micropython-m5stamp-c3u/commit/fe3ddc3d0c09cca4096dcfc37bbbf57e7b4a1271

It was (seemingly) caused by the QMP6988 chip in the ENVIII resetting in the middle of an I2c transaction during a requested reset (from line 97 of drivers/qmp6988.py), and the driver file not handling the timeout exception causing the exception/crash.

The fix was to just put a try/except around the transaction in reset(), and if the timeout is generated, ignore/handle it.

I found this with 5 minutes of googling. Not sure why M5Stack hasnt fixed it yet for all products that use the QMP6988

@isoeek M5Stack is different. For now at least, it does take a lot of data-mining effort to find information - which is a barrier to those of us with ADD/ADHD obviously.

Also, a lot of what exists is in non-english, as M5Stack's initial focus, going by social media, seems to be on Japan. And so there seems to be a heavier focus on cute "-chan" robots and "-neko" ears and that sort of japan-style "cute" stuff than stuff that would be generally helpful to your typical developer. But it seems to be financing their other development stuff, so whatever works, right? They are releasing new products every week now, so something is working.

Dont give up though. We are all struggling with lack of information/documentation, but I think things are heading in the right direction. UIFlow2 is growing, is a much better system, and eventually should replace UIFlow1.

Truthfully, I would have suggested they didnt release all the hardware before there was good documentation for it, but Im not in marketing, and it may not have been feasible. I guess all I am suggesting is "lots of us understand your difficulties trying to get accurate and usefull info/documentation, but dont give up."

We should also definitely support those people that are working to fix the documentation problem, like ajb2k3

and insaneLX's trick is very helpful

Also, see the readme text at https://github.com/m5stack/M5Unified

@werner_g
One comes withe the ATOM controller, one does not.

Where are the more current release announcement threads, for alpha 18 through alpha 29?

I cant find them anywhere.

@ajb2k3
They have responded and are cancelling the order at my request.

~~i placed an order with m5stack before their holiday shipping cutoff deadline, but they still didnt fulfill the order (just took my money) and now wont respond to questions.

what are my options?~~

They did contact me, apologized for the issue resulting in the unexpected delay in shipping, and agreed to refund me, so this is resolved.

@dawncold I also would like to know of any hid docs for the esp32s3

@ajb2k3 Can the stampS3 act as an hid device?

Does anyone know a way to have the Cardputer generate HID keyboard events to a PC, preferably via USB? Preferably driverless?

The reason I ask, is that physically, it would be great for something like the Duckypad programmable macropad style of tool.

https://www.tindie.com/products/dekunukem/duckypad-do-it-all-mechanical-macropad/

Each key could trigger a macro, and the info could be displayed on the display, like the duckypad, but you would have many more keys, and all the additional functionality if the stamps3

Any way to use the usb connection and have the device ack as a usb keyboard/macropad?

@ajb2k3 said in Core2 - Pullup resistor:

If 5v hits the GPIO pin it will kill the IO pin.

Well...poop. That explains a lot!

It is woefully out of date (from before any S3 products) but there is this:
https://docs.m5stack.com/en/products_selector

This is brainstorming and may be a stupid idea, but that doesnt usually stop me...

You could use one of these

https://shop.m5stack.com/products/grove2grove-expansion-unit

and run your charging cable through it. Every few seconds, your program could briefly disconnect the charging cable programatically through this unit, read the voltage from the battery internally while the charging has stopped, then resume charging. You would have complete control for an extra $4.50 USD. And you would also be able to display the incoming current/amps from your charging source during charging as well (since the unit can provide that info)
