The rom/miniz.h error occurs because newer board definitions (3.2.x) removed legacy ESP32 support. Downgrading to 2.1.x works, but to fix it permanently:

Manual fix: Replace #include <rom/miniz.h> with #include <miniz.h> in pngle.c (as noted in the linked guide). Disable auto-updates: In Arduino IDE, go to File > Preferences and uncheck "Check for updates on startup."

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

@kuriko Thank you!
I will use 2.14 for now.

@felmue Works for me too!
I never thought of that for StickCPlus2 !!!
Thanks

@teastain looks like it is available to be used with Uiflow2 now
CoreMP135 with Uiflow2

@ajb2k3 Sure, here it is:

Here is the full example for all ESP32s using the OV2640 camera in Arduino IDE
(in the IDE board selection choose M5Stack UnitCamS3)
Remember to edit the .ino file to include your WiFi credentials!

The full sketch is here:
 https://github.com/espressif/arduino-esp32/tree/cf448906b3836fbe9368934713b697469254c62f/libraries/ESP32/examples/Camera/CameraWebServer

You can choose CAMERA_MODEL_ESP_EYE, and apply a little tweak in camera_pins.h like this: 
https://github.com/m5stack/UnitCamS3-UserDemo/blob/main/firmware/src/hal/cam/camera_pins.h#L21

Also in the library used in your sketch
app_httpd.cpp
I had to change Line 77 from ('1" enabled) to ('0' not enabled )

#define CONFIG_LED_ILLUMINATOR_ENABLED 0

Successful upload serial output reads like this:

20:48:24.952 -> E (516) esp_core_dump_flash: No core dump partition found! 20:48:24.952 -> 20:48:24.952 -> ...... 20:48:24.952 -> WiFi connected 20:48:24.952 -> Camera Ready! Use 'http://192.168.0.37' to connect

There is also people in the discord cardputer community looking into adding a second bigger screen.

Stick with M5Burner as you will get the latest version without the need to compile.

Same as?

Thank you for the update.

Hello @teastain

your example looks fine to me. Nicely done.

Regarding submission: you can create a pull-request for yourself, inside the M5Stack repository, which adds your example and M5Stack engineers eventually will check it out.

Thanks
Felix

@felmue Thanks for responding Felix!
I am looking to hack the library, or my bad habit of dismantling one and putting the needed components "in-line" with the other code of the Main Loop in the Arduino IDE, but I admit that I am "Underwhelmed" by M5Stack's firmware and GitHub examples!!!
I would LOVE to access the STM controller directly and make the ext IO2 be a sta
nd alone processor, but whoa!
I'll keep in touch...Terry

CH34X driver for the CP2102/CH910?
I'm using the the CP210x driver and have it working

Hello @teastain

getting it to compile is probably as easy as replacing #include <M5StickC.h> with #include <M5StickCPlus.h>. The bigger issue is the larger screen size which will need to be adapted properly. If and when M5Stack engineers will fix that I have no idea. Sorry.

Thanks
Felix
