UI_Editor, released in December, 2018, is the latest software tool that supports assorted widgets such as pictures, buttons, gifs, and texts etc. UI_Editor provides a flexible platform that enables developers to easily edit their user interface and contents. Once the editing is done, UI_Editor can compile the result into a bin file. After the bin file is programmed to the SPI Flash of a UartTFT panel, developers may then control the UartTFT panel through simple instructions sent by the host MCU.
