Yes.

The file would need to exist somewhere, be it an SD Card, eMMC or QSPI.

You'd need a file system, and a block driver. Something like FATFS or X-FILE

You'd need to read and parse the data in small amounts, or buffer and break into lines. Basic STDIO file handling type stuff, like on a PC application, but using f_open/f_read/f_close variants furnished by your file system

Hello @ab73 ,

Yes it is possible.

Just look at how to read a data file in C ("C read file" on Google).

From there you can fetch your data and display it on a textArea widget for instance.

Please find here our guide on how to display dynamic data on a textArea!

File IO seems like some that would need to be part of the TouchGFX builds or demos, given the value and foot-print of such a use case?
