    Hi I can see that ILI9486l is supported. Is the ILI9486 supported as i can not see the GCLD_ili9486.ini file.
    I already have running ILI9341 works perfect. Looking to use a 4.0" tft. Pins are identical.
    Thanks

      glcd_ili9486l.h is the latest build. Looking at the change log is was updated last month.

      Get the latest build and all should be good in terms of the .h file.

      In terms of GLCD. If they both use SPI then the performance per pixel will be the same.

    currently using build 1247. When GC auto updates at start are the ini files updated as well?

    I am puzzled. What ini file? There is the library and there are demos.

    Sorry. Should have said include 'h' file. C:\GCstudio\Greatcowbasic\include

      Please check but the file should be there. It is shown in the Gold Build on GitHub. https://github.com/GreatCowBASIC/GCB_Gold/tree/master/Build/GreatCowBASIC/include

      The easy way to check .. test compile a demo that has that GLCD. If it compiles then all the prerequisites are present. If it fails, then, we need to figure out why that file is missing.

      Yes it does, the libraries are updated as well of the rest of the tool chain.

      also glcd_ili9486l.h is available on build 1247

      If for any reason you still don't have it (ie: if deleted accidentally), simply do a force update and GC Studio will repair your build and place it again.

    glcd_ili9486l.h is in the include directory. This display has the ILI9846 chip. If i use the attached GCB with the ILI9341 display works perfect.

    here's the GCB.

    I think that you are sharing that the glcd_ili9486l library is not working with the specific display. Are you saying this?

     
  • Mikam

    Mikam - 2023-05-17

    9341.

    Sharing? saying... yes

    As there is no marking on the GLCD .. how do you know it is an ILI9486L ?

    The ILI9486L I have do not look like that.

    First job is to review the sale listing. Please post.
    Second job. Operate the WHOLE solution at 3v3
    Third job it does not work. Try without HardwareSPI at 3v3
    Fourth job... Try the ILI9341 library. Wont do any harm to try at 3v3
    Fifth job. I would recommend I stop guessing and adapt .... C:\GCstudio\GreatCowBasic\demos\GLCD_Solutions\GLCD_Discovery_for_MCUFRIEND_devices\GLCD_Discovery_SPI_Data.gcb for you chip/config. Then, share the results displayed on the terminal.

    ebay listing: 275576588073 4.0". The display supply and data lines are 3.3V. will try your other recomendations.

      The listing is for a ILI9486 which may be different.

      You need to determine what this using the SPI discovery program.

       
  • Mikam

    Mikam - 2023-05-17

    This is what the ILI9341 driver does. I doubt if its the 9486.

     
    • Anobium

      Anobium - 2023-05-17

      ok. Good. You have comms.

      You need to run the GLCD discovery. The dump of the registers will inform.

       
  • Mikam

    Mikam - 2023-05-17

    I gather i can only run GLCD discovery with the 328, which i don't have.

     
  • Anobium

    Anobium - 2023-05-17

    No. Use the pic one or convert.

     
  • Mikam

    Mikam - 2023-05-17

    Finally. Thought the 9488 driver was only for 320*240

     
    • Anobium

      Anobium - 2023-05-17

      Clearly not... looks OK.

      Job done. :-)

    Spoke to soon. Still not right. Colors are not correct.

     
  • Anobium

    Run the discovery program. I am not guessing the CPU of the GLCD. We need the datasheet and the correct datasheet.
