@literakl so are you able to display current time and battery level at all...forget about sleep option for now

@dingfanshou said in key:

Why can't it connect even though the password is the same?

In the config I see "Start Mode" is "USB Mode". This means, your device is not connecting to WiFi at startup unless a previously stored program does. Change the mode and try again.

Hello @RubberDuck

I can confirm the shark fin like signals on my M5CoreS3. I am no I2C expert, but I think they might be marginal and so maybe just barely working on one M5CoreS3 but not on the other when talking to AXP2101. Maybe a stronger pull-up resistor might help?

BTW: I checked the I2C SCL line on an M5Core2 and it is much more rectangular, e.g. much more like I would expect it.

Thanks
Felix

@teastain good morning and hello,
I want to integrate the AXP2101 chip into esphome. I think my programming skills aren't sufficient.
and i cannot find a functioning example. thanks for your help and a nice day.

Hello @scroggyg

I modified my test program to use internal I2C, did a i2c scan w/o ExtIO2 connected and with it - there seems to be no i2c address conflict.

For me ExtIO2 works either connected to port A or to internal. What I noticed though is that I need to wait (after powering up M5Tab5) for the UIFlow2 screen fully being loaded before running the program.

If I do not wait long enough I occasionally see a crash too.

Thanks
Felix

@wavydavy
Yes, that resolved the issue, I am now using the
"M5Stack by M5Stack official 3.2.2 installed " board def.
The entire problem was that my pre-existing code AND the M5Stack Github examples by M5Stack use
#include <M5Stack.h>
instead of M5Unified.
Thanks for your help.
Also:
No one at M5Stack picked up on this, except you, not even the online M5Stack AI chat helper.

Note: The examples in the newer web based API work fine, just not the old M5Stack official Github.
Cheers, Terry

@hacxx said in rom/miniz.h error still occurs when compiling for Core with board def 3.2.x:

M5Stack isn’t abandoning older Cores, but newer SDKs drop deprecated APIs. If issues persist, stick with 2.1.x or modify the library.

Open source is great - until libraries get modified and changes are made that impact existing functionality... M5Stack isn't alone in this - it's a problem that spans the open source community.

I get that technology is always changing... But there must be a better way to manage libraries. If I didn't stumble on these websites, I'd never have found the solution and it's very likely that I'd toss my affected M5Stack gear in the bin because it's basically unusable. And then I'd move on to a competitor's products that work.

@Omurice Bump Thread,

There are three threads on the PWRCAN Module, and all of the say the demo does NOT work. I tried to use TWAI based code but it doesn't seem to work either.

Is it possible to get a working demo on a CoreS3

Ok, it worked finally. At least, I needed to use module_llm.melotts instead of module_llm.tts.

The model specification in tts_config doesn't matter for my case. It picks melotts-en-default somehow automatically even though the default value is melotts_zh-cn.

The module is very unstable when the controller is powered on. It requires several clicks of the reset button until it finally speaks. (The return value of melotts.inference is -97 when it's successful.)
