These displays do not work through a USB to UART converter, only through a special connector. Use Stone Designer to design the interface, then click the Debug -> Download menu in it and specify the place where to put the created project, there the program will create the “default” directory and write all the project data into it. Create the directory “STONE\Project” in the root of the USB flash drive and copy the “default” directory with the project data into it. That is, if you have the name of the connected flash drive E:, then you should get E:\STONE\Project\default . Well, several directories with project data inside this path.
Set the switch on the display to the “Host” position, turn on the display and insert this flash drive into it.
