how can i tranfer a file to sd card to use in tjc usart hmi?
when i copy a file to sd card and put in lcd tjc it don`t recognize
I tested a lot SD-Cards on Nextion 3.2 Inch and 3.5 Inch.
Most work at 3.5 Inch but 3.2 Inch does not accept newer types. So i ordered “old slow” max 4GB. Hard to find as they become all faster and bigger 
Don’t know why there is a difference but 3.2 seems to be more sensible than 3.5 Inch Displays.
