  • do you have tested my with arduino ide?
    thank you



  • 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?
    I



  • Agreed, Following this myself and just get a blank screen with the image not loaded. This is my image 0_1529644400361_logo.jpg



  • @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?



  • 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.



  • I use a SD 4mo FAT32



  • and also
    I tested with a 32mo



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



  • @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!



  • 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.
