Thanks for the tip @flypeek

I checked with my Hello World code and this worked.

I did not expect the AtomS3 to be that different to the original AtomMatrix. However I just confirmed if I change the "board" to just M5Stack-Atom all the original code compiles.

I would have expected big changes if we referred to the ESP32-C3 with the new RISC architecture, but the S3 was fairly similar I thought.

I presume it has a new board definition due to the LCD screen on the AtomS3. If I can get the Zigbee unit working nicely, I might port the example over and post up a PR in the AtomS3 library.

Many thanks again @flypeek you have unblocked me and I can keep moving forward (I hope).

By way of a follow up, I'm inclined to suggest the M5Stack library 0.4.2 is broken.

#include "M5Stack.h"

void setup() {
  // put your setup code here, to run once:
  printf("Hello World");
}

void loop() {
  // put your main code here, to run repeatedly:

}

Still produces the same exception above:

This is using Arduino IDE 2.0.4 trying to compile for M5Stack-AtomS3 board

I'm currently exploring the world of Zigbee and got the sample code here:
https://github.com/m5stack/M5Stack/tree/master/examples/Unit/Zigbee_CC2630/P2P_TEST

Although when I try to compile it in Arduino I get this error:

Hi Folks,

Just thought I'd try using UIFlow 2.0 with my Atom S3 before I go down the Arduino rabbit hole.
https://docs.m5stack.com/en/unit/zigbee

I noticed in the configuration panel on the left, it only had Pa.HUB, ENV, ENVII and ENVIII, not the Zigbee unit with the blue grove plug. So I might assume this unit is not supported in UIFlow 2 ?

I tried using the UART and got as far as:

from hardware import *

uart0 = UART(0, baudrate=38400, bits=8, parity=None, stop=1, tx=2, rx=1)

while True:
    if uart0.any():
        print("\nFound Data:", end="")
        print(str(uart0.readline()))
    else:
        print(".", end="")
    sleep(1000)

But given how proprietary the CC2630 is, I expect that's as far as I'm going to get.

I found these examples here in C:
https://github.com/m5stack/M5Stack/tree/master/examples/Unit/Zigbee_CC2630

.. which do not show how to pair sensor and read data from them. Has anyone got examples of how to do this with the UART interface ?

Finally got the notification today and put an order in.

I was tempted to order a heap of them, but given they are obviously in short supply I ordered a minimal qty so I hope others can get some too. They look fantastic!

Only place I could find them listed was on Mouser which cites 9-week lead time, earliest stock been 07-April-23.

@ajb2k3 Do you have a link to the pre-order as I cannot find anything ?

Site still says out of stock, so its still all hype for me. Promises to be a good thing, I just hope it delivers one day.
Until then, I'll keep doing projects with the Atom Matrix, its real and a known thing we can get and use.

@saitotetsuya said in ATOMS3 out of stock ?:

https://twitter.com/M5Stack/status/1607967462393511942

Jimmy-san says it is in Mid-February.

Looks like Jimmy-san is full of it. Still out of stock, feeling a bit like vaporware.

Anyone know when stock will be arriving for the ATOM S3 ?

I have had a lot of fun with the ATOM Matrix, but the S3 looks fantastic but no one seems to have any stock.

My question is around timing. Should I wait ? how long do you think it will take ?

@felmue Yes, I think you are absolutely right.

I just struggled to find any useful references to do this.
Today I came across this post:
https://forum.micropython.org/viewtopic.php?t=5320

So I will try this later today and see how I go.

Hi Folks,

I'm trying to get 2 M5Stack Atom's to talk together via I2C, or more specifcially, SoftI2C in Micropython.

I've flashed both devices with Micropython 1.18 and have code on device A that looks like:

import machine

i2c = machine.SoftI2C(scl=machine.Pin(26), sda=machine.Pin(32), freq=400000, timeout=50000)

data = i2c.readfrom_mem(2, 1, 10)
print(data.decode('utf-8'), end="")

Then on device B, I have the code to send data:

import machine

i2c = machine.SoftI2C(scl=machine.Pin(26), sda=machine.Pin(32), freq=400000, timeout=50000)

i2c.writeto_mem(2, 1, bytearray("Hello World"))

Nothing seems to come through, I have tried i2c.scan() however it just returns and empty list on both.

I realise these are not hardware I2C pins, but they are for the Grove cable I'm using to power the second Atom.

If anyone has any examples/reference/docs or general tips, that would be great.

I have the same issue when I use the M5Stack ESP32 Downloader.
However when I use a simple M5Stack Atom Matrix, its works fine.

I am on OSX Big Sir.

I feel like the issue is related to the CH9102 chip on the ESP32 Downloader where the Atom has the CP2104 I think.
This theory is supported by this article here:
https://blog.squix.org/2021/08/ch9102-driver-issues-failed-to-write-to-target-ram.html

Confirmed, installing the driver from this thread here worked for me
https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/issues/139

Hi,

This is not strictly M5Stack's issue, but I have started designing my own little device to plug into the M5Stack.

Does anyone know where to get the Grove sockets ?

I found a place called SeeedStudio which looks like 114020164 is right, but I cant fine a symbol or footprint file for them.

Does anyone else make them ? someone with libraries to put it in my design ?

Hi Folks,

I've been looking at thise C code here:
https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/ResetReason/ResetReason.ino

...and wonder if there is a way to get a more detailed message ?

I'm using the watch dog timer, which works great, but I loose any information about why it didn't complete the task in time, all I know is that it failed and the WDT rebooted, but I never know why.

It would be great if I can redirect the serial console output some how and persist it over the restart.

Awesome! Thanks, just ordered 20 of them. :)

The assembly part looks like fun, and its still consumer friendly with no soldering required.

If I have an M5Stack Atom Matix is there a simple add-on camera without getting a whole new ESP32 controller ?

Ideally, if there was an I2C camera in consumer ready package with a grove connector or something ?

I was looking at this one:
https://shop.m5stack.com/products/psram-camera-module?variant=31980593774682

But it seems to add a lot more than I need.

Hi Folks,

Wondering if anyone has a sample to draw a graph on the Atom matrix 5x5 LED ?

I have in mind to draw a line across the screen tracking temperature.
If I have a 25c range then I can round my values to fit into 1 row per 5 degrees.
I can then render the last 5 values horizontally across the screen.

I am optimistic someone has a library to do all the maths for this and I can just feed it 5 values ?

If not, I might have to come up with my own.

By way of extension, the bluetooth statck doesnt seem to be in the UI Flow 1.7.6 image for the Atom Matrix:

On the box is says BLE ...

Just not implemented in the UI

Hi Folks,

I'm new here, just picked up my first device, an M5 Atom Matrix.

I've spent a day watching videos about UI Flow which is a really neat way to get started. The only notable omission is - no Bluetooth!
It lists BLE as a feature on the box and it is supported by the processor, but just not exposed in UI Flow.

This is sad as its a big step from using M5 Burner and UI Flow to get started so easily to now compiling MicroPython and bundling packages into it that I can push down onto the device manually. I really hope I don't end up going to C with PlatformIO to use the device.

Even if Bluetooth wasn't exposed in UI Flow, but the python bluetooth module was installed in the UIFlow_Matrix image (currently 1.7.6)
