fine, but does not work on ide arduino.
can you send me your code in espi setup?

Richard

do you have tested my with arduino ide?
thank you

Richard

i have install PlatformIO and load my projet:
Wrote 230992 bytes (123957 compressed) at 0x00010000 in 11.0 seconds (effective 168.6 kbit/s)...
Hash of data verified.

Leaving...
Hard resetting via RTS pin...
====================================================== [SUCCESS] Took 23.68 seconds =======================================
I still have the problem!
hardware problem?

Agreed, Following this myself and just get a blank screen with the image not loaded. This is my image

@richard No. i didn't tested with arduino "ide". I uninstalled that from my PC because is mostly useless...

I use Visual Studio, Eclipse or PlatformIO.

I uploaded the PlatformIO project for your code to github: https://github.com/botofancalin/M5StackJpgtest
The M5Stack library is already installed local into project.
All you have to do is to download the repository and compile the code.

Maybe a stupid question (or two) but I'm going to ask anyway.
Is there a hardware limitation for this i.e. is there a card size limit and a formatting requirement?
Is there a specific image limitation for the image?

Richard

I use Visual Studio too.
i have just tested your programm and i still have the problem.
I think it's a hardware problem.
I'm waiting for another device
Thank you.

I think there is no limitation on card size.
There might be a limitation on card read/write speed and that depend on the sdcard manufacturer and model.
As i know, the cards formatted as FAT32 are preffered.

That problem can be caused by the ILI9341 controller from the TFT.
If that is the case, the only solution is a replacement.

Richard

I use a SD 4mo FAT32

Richard

and also
I tested with a 32mo

ajb2k3

I have a 32gig Class 10 sdhc formatted as fat32 MBT.
How do I tell if I have the ILI9341?

Calin

@ajb2k3 ILI9341 is the LCD driver used by the M5Stack TFT display: https://cdn-shop.adafruit.com/datasheets/ILI9341.pdf

Ok, failed to get it to work with the jpgdraw script but if I convert to array it works, But!!!!!!

I had to reduce the image to a 256bit Indexed image!

Richard

I tested my programm and my file jpg (sd 4go) with IDE Arduino 1.8.5 on another M5Stack .
It works very well.
The first M5stack doesn't work propely.
I hope the M5stack store will change it.

Thank you Calin!
