Thanks, that helps a lot. This is my first use of the Unit devices. I've use the HAT on the M5
which obviously is only 1 at a time.
I'll get the PbHUB and the I2C version of the Ultrasonic Distance Unit.
I'm working on many sensors to help disabled users. These sensors help those in
wheelchairs where they might not be able to even touch buttons. So providing a multitude
of options (motion, tilt, distance, LUX, buttons) - even the touch of the Core2 is very sensitive
which is good.
Thanks,
I wanted to follow up on the power of OTA (Over the Air) update. With the USB wire plugged into the M5, and uploading a 'bin' via compiling, many times it gets a hiccup, and stops. Many times redoing works, but it's frustrating.
But with the OTA - In arduino I can sketch->Export to Compiled Binary. Then I copy that 'bin' to the cloud storage via 'ssh'.
Then I have various ways of telling your M5 to grab that new OTA file. It takes a minute or so depending on the size.
So this OTA process can many times be easier than uploading via the USB cable. I even use the Serial monitor to take inputs from the user, such as perform an OTA from that new daily build file.
Also, I can update devices throughout my deployed M5 units through a similar process (sending an MQTT message to them).
I have the Core2 working with almost the same display as the M5 and the 3 capacitive touch buttons are working (as M5.BtnA and M5.BtnB in my case). So I can mimic the M5's A and B buttons.
My question is whether the small circles can be colored so they can be seen, as this is outside the LCD display drawing.
Note: I had been trying to get the M5StackC-Plus to absorb the M5Display from the Core2 - but that was not going anywhere. Turns out the M5Core2 libraries had most of the M5Stack code so things compiled and worked (including MQTT, etc).
@robski not that I know of. As I mentioned, the USB-C works fine. It's the USB-A that is hit or miss on working. I think this is a mac issue as I search the net. Eg: here and here and mac ports
Just was wondering if anyone has had this issue as well. I'm not stuck but my co-worker (not a developer) couldn't get the USB-A on a mac dongle to work. I just wanted her to use the Serial Monitor - as I implemented commands the user can type is to do an OTA update or other things. So they just needed a Serial Monitor (and this issue crept in).
Thanks.
@robski I did some testing. When the USB-A is plugged into a PC (com4) it definitely works - is recognized, etc. But using that same cable (and a couple others) the M5Atom is NOT recognized on the MacBook (sometimes).
A teammate still cannot get the USB-A to work on her MacBook. (I'll mention the dongle issue stated below).
Now for the strange part: After testing the PC, I plugged the same USB-A into my Mac and it was working. So I thought the PC somehow altered the M5Atom.
But trying a brand new M5Atom - it works on PC, but not on the MacBook. (So that altered theory was debunked).
It's strange that looking at a post here from 2020 - the problem was reversed: the USB-A was the only one that worked on MacBook.
I just tried a non apple dongle, and it is working. Most interesting.
Strange, after working with that non-apple dongle, I re-tried the apple dongle,
and it works now (on this M5Atom).
Maybe the MacBook get's woken up after and recognizes that device once. I just tried a brand new M5Atom - and it didn't recognize it. Then started to recognize.
Recently with the M5Atom, only the USB-C to USB-C cable from my MacBook is recognized as a valid PORT. If using USB-A the port will not show up.
Some teammates were trying to just use the Serial Monitor- and did not have the USB C - USB C cable. Although in this case, they say the PORT shows up, but is just not selectable. I haven't seen that - it just doesn't show up for me.
I have tried many different USB-A to USB-C cables, and none work.
It would be nice for M5Stack to chime in and let us know what works.
@kuriko Dupont, that looks promising. Thanks. For the 4 pins of the HDriver to the 4 pins on the M5Atom (and 2 other pins too) - I would need a female at one end, and a male at the M5 end.
You gave me a good path forward.
Hi, we have a nice 3d printed unit to house the M5Atom, and HDriver, Buzzer, and a Stepper Motor. This replaced an earlier custom board with the ESP-32 chip.
This is an automated Dog Feeder called PetTutor that we can mount on a wheelchair or basically anywhere else.
Anyway, are there Plug like cables that are better than the Breadboard Jumper Cables? The pins on the boards and even the M5 Atom are wider than a Grove cable. Is there a term for them?
This shows the Grove cable on the bottom. Does the top cable have a name/standard? The pins are wider. These are from the Stepper Motor and plug into the ULN2003 HDriver board (the one not labeled HDriver) (turns out the M5 HDriver couldn't power the stepper motor with enough torque. Instead we use this ULN2003 driver.)
What we want are plugs like this that can plug into the M5Atom and into other pins (basically like the HDriver from M5 - on left). So a male plug into the M5Atom and a female into the raw pins of the Driver board (Upper middle).
This shows a finished version with those jumper cables (and I need shorter ones). The lid with the motor goes in right on top of the blue case. (The stepper isn't plugged in yet). There is a small black buzzer (optional sound) under than blue angled piece.
We are looking for any ideas on making these connections more rock-solid like the Grove or other plug-in wires.
@Jennyrich789 Good stuff. I've been integrating a lot of those types of sensors, and I use the Tailbat for the battery. We are centering all our work around the M5Atom now, such a powerful computer.
My biggest challenge is getting the IR and RF to work. I finally got volume to my TV to work (which was IR), but then these new remotes use RF for the rest.
If anyone has a good approach to getting these to work, learning the commands, etc. That would really help me out. I have disabled users that could really use this driven from my M5Atom.
I too have the ATOM_SPK and the sample programs run but create no sound, even with the earphone jack.
https://docs.m5stack.com/en/atom/atom_spk
The PlayRawPCM program runs but no sound.
Also the PlayMP3FromSD is missing files, such as AudioFileSourceSD.h.
I can get the beep program here to work
https://github.com/PaulskPt/M5Stack_M5Atom_EchoSPKR
But it seems this program makes a constant hum sounds always, and the beep when button pressed. I assume the battery will die faster too.
ps. What's up with tagging posts as being "OLD" - when it's a year ago, but the programs being tried are 4 years old. It sure seems to me that the "thread" of any issue, even decades old, should still be used to keep that context intact. Oh well..

@samlevy0515 I just got the $10 GPS Base 2 - and it works great. The M5Atom plugs into like all the others (QRCode, HDriver, etc). https://shop.m5stack.com/products/atomic-gps-base-v2-0-atgm336h
I've had the M5 with its display working for a few years. I'm onto other ways to share the information (over MQTT) and other apps (like iPhone apps, etc).
As for "cases" we are really into the 3d printer - and have some custom devices that house the M5 parts. We really like the small M5Atom. The amount of software that can be housed is impressive.
Look at some of our devices (eg. for Dog Feeding) mounted to a wheelchair, controller via BLE or MQTT.

@williamsmaith just let me know. I have over 700 clients using the system with a remote dog feeding application. I even have a client using eye-tracking to send messages to feed his dog (as the feeder is mounted to his wheel chair). - cheers.
