drawJpgFile / drawBmpFile

[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.

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 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

[ajb2k3]

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.
