Looking for Factory Test Source code for Core2

jdonth

Hello,
Where can I find the source code for the Factory Test Project for the Core2 under arduino?
I just bought my first M5Stack Core2 and am trying to get my head around the programming environment.
Thank you in advance.

Hello @jdonth

try this link.

Thanks

jdonth

Thank you very much!!!
It worked. Now I can start learning what the Core2 can do.

jdonth

I spoke too soon.
The microphone doesn't work (at least the Sound FFT display does not indicate any sounds being picked up.)

The compile gave the following warning:
C:\Users\jld\Documents\Arduino\Core2_Factory_test\Core2_Factory_test.ino:292:33: warning: 'I2S_COMM_FORMAT_I2S' is deprecated [-Wdeprecated-declarations]

Any thoughts?

Hello @jdonth

my best guess would be that the code has not yet been adapted to Arduino framework 2.0.1.

Thanks
Felix

jdonth

@felmue
Thanks for the assist. Any idea what version of the framework does work? That will save me itterating backwards through the install list looking for the "winner".
Thanks,
Joe

Hello @jdonth

probably the last of the 1.0.x versions.

Thanks
Felix

jdonth

@felmue
No joy. I installed and tried the following versions:
1.0.6
1.6.0
1.6.13
1.8.0
1.8.18
Some of the earlier versions would not let me add external boards (M5Stack) but the later versions that did, still gave me the i2s error (which may or not be related to the no microphone).
Thank you for your effort.

Hello @jdonth

what I meant by Arduino framework version 1.0.6 is the arduino-esp32 framework version 1.0.6 (instead of 2.0.1) and not the Arduino IDE. Sorry if I wasn't clear.

BTW: when I run the app compiled with 2.0.1 I see this error in the log:

E (2888) I2S: i2s_check_set_mclk(253): ESP32 only support to set GPIO0/GPIO1/GPIO3 as mclk signal, error GPIO number:6
E (2895) I2S: i2s_set_pin(314): mclk config failed

I was able to fix this error by adding this line in function InitI2SSpakerOrMic():

tx_pin_config.mck_io_num = GPIO_NUM_0;

Thanks
Felix

jdonth

@felmue
I'm lost and am sorry to take up so much your time.

I tried your fix to InitI2SSpakerOrMic and it threw so many errors I knew I lost.

How do I tell the IDE to load the 1.0.6 framework?

Here is the compile log. If you can see what might be wrong?
(I edited the ...Writing lines before the 100%)

Thanks,
Joe

@felmue
I just tried the Speak project and it will not "speak" the Dongdong code.
Perhaps knowing that both the microphone AND speaker do not work might point to where the problem is???
Thanks,
Joe

Hello @jdonth

No worries. I am sorry it still doesn't work for you.

How do I tell the IDE to load the 1.0.6 framework?

That I don't know. I am not an Arduino IDE user. I suggest you ask this question in an Arduino forum.

I do get those warnings in the compile log as well, they are not (yet) critical. Depricated only means that in the future this part of the code will be removed / modified and them most likely lead to an error / non working code. I guess if you'd like to get rid of these warnings you could replace I2S_COMM_FORMAT_I2S with I2S_COMM_FORMAT_STAND_I2S.

Do you have the run log? Maybe there is a clue in there.

Thanks
Felix

Hello,

Just to be sure this is not a problem with your unit, I would suggest you download the EasyLoader tool you can find the link on this page: https://docs.m5stack.com/en/core/core2

This tool allows you burning your Core2 with the stock demo program so that you can test it without having to compile it.

Should be a good start

jdonth

@erich
Thank you for your suggestion. I downloaded and ran the EasyLoader code and my unit runs the Core2_Test with the proper microphone (per the FFT bar graph).

Compiling the code at https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Core/M5Core2/Arduino/Core2_Factory_Test

When I run the Core2_Factory_Test I get no microphone indication (and the speaker is silent during the scrolling test phase).

I am assuming I have some misconfiguration in my Ardunio IDE but I don't know where. The following is the compiler messages from when I compile the test program (sorry for the size, I don't know what I can safely edit, except for [many] repeated warning:excess elements in array initializer):

Hello everyone, I have several M5Stack Core2s and since the last update of the M5Stack boards in Arduino it stopped working for me.
I don't know where to go and the error I get is:

The precompiled binary factory test if found in the M5Burner firmware download program.

Thank you Felix! I'm glad I found your solution for this error. It finally works. I'm using version 2.0.2. I can now run the EchoSTT on my Core2.

@jdonth I'm not sure if you fixed your error. I have the same deprecated error. But it still can get compiled. My suggestion is to update the M5Stack libraries. This is what I did.

Hello, I'm getting a similar error, trying to use the arduino samples for the M5 echo. Please let me know how I could resolve this. Thanks!
