To change the image of the STONE logo on your SWTI080WT-01 display, you need to make sure that your 24-bit BMP file is saved as “logo.bmp” in the “E:/STONE/logo/” directory. If you have already done this and the image still hasn’t changed, please make sure that you have properly connected your display to your device and that your device is configured to display the image correctly. As for changing the “STONE UART Parsing Library” to use TX3 and RX3 on serial port 3 to send and receive data from the STONE display, you will need to modify the library’s source code to support this configuration. This can be a complex task and may require a good understanding of both Arduino programming and the STONE display’s communication protocol.
