Customising the splash screen



  • Hello,

    I am trying to change the main logo of my PanelDue-5i.
    I upload the firmware with the logo that I want to show in the PanelDue but I think something is wrong.

    • I use bmp2c-escher3d.exe myimage.bmp myimage.bin -b-c to compress the file, but is always 751kb, and the original is 13kb.
    • I also try to compress a white picture and also is 751kb.

    In both cases, when you combine firmware and logo, it is too heavy.

    I have also tried a combination with firmware copy / b PanelDue-5.0i-7.0i-nologo.bin + myimage.bmp PanelDueFirmware.bin, this was OK, 131kb, but when I upload it the logo does not appear.

    Must the logo have a special name? Something that i am doing wrong maybe?

    The picture of the logo is 800x480 pixel in format .bmp of 24bits.
    I use the commands with a .bat file.

    I made with other picture sizes and formats and the same problem.

    try dropping the colour depth significantly?



  • Try making sure you have a space between the two command line switches
    bmp2c-escher3d.exe myimage.bmp myimage.bin -b -c and not -b-c.

    I have successfully converted a 1126kb 24 bit bmp file to a 106kb bin. My firmware bin after the binary copy is 224kb. The bmp file needs to have large blocks of colour. Too much detail will not convert successfully.

    I presume you are following the instructions on github for the PanelDue firmware.

    Thank you so much. That was the problem, the space.

    It was driving me crazy

    Thanks a lot again!



  • Glad I spotted it! Falling back on my original DOS 2 and 3 experience!
