Ok, it seems that the problem was due to my version of ESP32 tools.
I updated my ESP32 framework and now the code is working fine.

Also, I used PlatformIO in VSCode which make things simpler since it enables the M5STACK_FIRE flag during compilation.

Thanks

That worked for me

Thanks for the tip. Will do!

Hi
I'm having the same problem with the M5Stack/Advanced/Display/TFT_Screen_Capture example just get white screen captures (0xFFFF for any pixel )

@julian Exactly what I need, many thanks

Thanks a lot Osmar.

This camera indeed works with the M5Stack, and is indeed very easy to hook up. This post is to document what I did.

Simply buy the cam at the link supplied and hook it up with the pin-socket-wires that come with the camera as follows:

Then clone https://github.com/ArduCAM/ArduCAM_ESP32S_UNO and copy the ArduCAM and ESP32WebServer libraries to your Arduino/libraries directory, add the client or AP data to the example script from the github (ArduCAM_ESP32S_UNO/libraries/ArduCAM/examples/ESP32/ArduCAM_ESP32_Capture/ArduCAM_ESP32_Capture.ino). Also make sure you uncomment #define OV2640_CAM and #define OV2640_MINI_2MP in the memorysaver.h file in the Arducam library dir, run the script and a webcam webserver works. (Surf to <ip>/stream or <ip>/capture).

@Calin Thanks!

I tried PlatformIO and didn't like it, maybe I should have tried longer. But if you're making something to be this easy to use, the Arduino IDE is where the users are, so I would always create for it as the primary way for people to use it.

I know the JPGs take up space in flash (but 1 byte per byte, not more than they need, right?) I'd also like to know what the space in the compiled image is used for, can you also list that? There were some weird jumps in how big the image got while I was developing.

What exactly do you call "normal code"?
Without a code sample, this community won't be able to help you...

I had no problem running any ESP32 code on M5Stack, after i made the proper modifications related to GPIO assignment.

@ajb2k3 I mean, isnt that exactly what the QWERTY FACES module would be good for?

@gabi 在 How I can run espruino / javascript on the M5 Stack? 中说：

how can I make the web IDE connect to the device?

You should change the Web IDE baudrate to 115200 (in the settings page)
