    in Support

    Posted · Edited by madhu

    No it depends on demo what we are running.For example if I run button demo it looks different and if i run widget demo it looks different.

    Note:And also my board got splash screen when I turn on the board it I'll come and it I'll remain until run any framebuffer demo

    Hi,

    whatever the keys  I'm using are gpio keys(Total 6 keys) . I have written a small  C application to print key events.

    Following are the keys with event codes.

    event type 0 (Sync)

    event type 1(Key)

    event code   1:Esc

    event code 28:Enter

    event code 103:Up

    event code 105:Left

    event code 106:Right

    event code 108:Down

    Here I have a bit confusion how to write a board file with these keys.

  16. Linux framebuffer problem

    Hi,

    Still I'm facing flickering error with my frame buffer demo. My display is 24 bpp with 320x240 resolution.

    I'm successfully running normal frame buffer application which is attached in the attachment. I'm suspecting there is a problem with pixel format.

    I'm setting GDISP_PIXELFORMAT_RGB565 at board file if it is not correct please let me know what is the correct value or I need to change any thing else?

    Hi,

    Sorry for the late replay.

    This problem(Text resizing) I'm facing only in visual studio.Follow the steps to recreate the scenario.

    1.Create a project in visual studio.

    2.Just add only text edit and key board widgets to the window.

    3.compile and try to write something into text edit  through keyboard.

    4.Try to resize the text by pressing backspace.

    Hi,

    I'm developing UGFX windows native application using visual studio.I made a demo with multilingual, screen transition and widgets. Everything is working fine except text edit widget.

    Actually I'm able to write data into text edit widget by using keyboard widget but when I'm resizing (Means while pressing back space in keyboard) I'm getting a exception(Invalid allocation size).

    seems some problem with gfxRealloc(). But in ubuntu I did not  face any problem with text edit widget there it is running smoothly . Please suggest me how to solve this issue.

    Hi,

    Initially I ran my demo in normal user so it didn't work. So later I have done some research regarding frame buffer  then I come to know that I should run my demo with root user.

    So I tried with root user and it started working...

    Hi,

    I solved "GDISP Framebuffer: Error opening the framebuffer device " and I'm successfully running ugfx with framebuffer in my host pc.

    But when I'm  running it in my target machine(armv71 with linux kernel 3.0.35) I'm  getting one more error "Gdisp framebuffer: dispaly is 24 not 32 bits per pixel ".

    How to enable 24 bits pixel format?
