Hello @felmue,
I know the part M5CoreS3 Library and the examples. With some effort I would get it working for the Arduino IDE, but this means a lot of manual work.
I am looking for a working environment for easy examples.

@sgu
Yes, this is pure product placement with a few simple examples.

I use the Arduino IDE 2.1.0 and this standards:

• Additional boards manager URL: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5unified_index.json
• M5Stack Library: M5Stack from M5Stack, Version 2.07 (according to the description it should work with M5CoreS3:"Boards included in this package: ..., M5Stack-Core3,..." )
• Program with "#include <M5CoreS3.h>"
  -> The error is:

"/Users/*/M5Core3/CamToLCD/CamToLCD.ino:6:10: fatal error: M5CoreS3.h: No such file or directory
 #include <M5CoreS3.h>
          ^~~~~~~~~~~~
compilation terminated.

I looked at the Library at directory "/Users/*/Library/Arduino15/staging/libraries" and found no M5Core3-Code-patterns!

Hallo @felmue,
nice to meet you here again. What software did you use for your example? "Arduino IDE 2.1.0" and library "M5Stack V2.07."?

@ajb2k3 The factory source is not at the GitHub link " https://github.com/m5stack/M5CoreS3" or I didn't found it. I found their only utilities and little (!) examples, but not the whole "factorytest.ino"

@ajb2k3 I'm not looking for UIFlow 1 or 2, but "only" the one example that is also installed on the M5Core3. I am aware that a new product needs some time to create the documentation and software.

@ajb2k3 I know this standard resource. I found their only utilities and little (!) examples, but not the whole "factorytest.ino"

Hello, where can I find the factory test program for the New M5Core3? I am very interested in the cam Part of the software.

Hello,

after three years is it possible to show a static WebPage on the M5Stack/M5Core2?
Anyone has an idea?

Hello,

I used ESP-IDF v4.4-beta1, Arduino 2.0.2 for and M5Core2-Library ("0.1.0" = newest version, I also checked 0.0.3). The Arduino libraries I got from "https://github.com/espressif/arduino-esp32.git" and the M5Core2 Library I loaded from "https://github.com/m5stack/M5Core2.git".

I can initialize the M5Core2, write text on the screen and connect to wifi. If I activated the SD-Card I got an error: "A stack overflow in task main has been detected."

I looked for the cause and it are these calls:

bool SD_Enabler = true;
M5.begin(true, SD_Enabler, true, false, kMBusModeInput); 
   -> SD.begin(TFCARD_CS_PIN, SPI, 40000000);
      -> if(!sdcard_mount(_pdrv, mountpoint, max_files, format_if_empty)){
          -> FRESULT res = f_mount(fs, drv, 1);

The reason for the stack challenge is f_mount.
There are only two parameters for this function:

FATFS* fs;
char drv[3] = {(char)('0' + pdrv), ':', 0};

The value for drv is "0:" and seemed okay. The parameter fs was initialled some lines one before without an error:

  esp_err_t err = esp_vfs_fat_register(path, drv, max_files, &fs);
    if (err == ESP_ERR_INVALID_STATE) {
        log_e("esp_vfs_fat_register failed 0x(%x): SD is registered.", err);
        return false;
    } else if (err != ESP_OK) {
        log_e("esp_vfs_fat_register failed 0x(%x)", err);
        return false;
    }

I didn't know what happened. Have anyone a good idea?

Hello Felix,

thank you for your quick answer. I can ping sometimes and I cann't surf the Internet with my phone or with my computer and eth2ap-modul.

• I have changed the channel the softAP is using. Small changes in quality can be seen, but no significant improvement.

• I tried a different wireless client, for example my computer and my phone.

• I used a 12V/3A power adapter on LAN-Module with W5500. The M5Core2 and the LAN module also run stably with other applications and the same power supply.

Bye,
Uwe
