    Meldavia,

    Thanks a lot for this ehancement.
    So, if I understand well, the only thing to do is :

    disp_SetReg(0x36, 0x00);
    gfx_Cls();

    And the RGB configuration will be updated ?

    What a good new for me !
    Waiting for PmmC R28 to be released.
    Thanks to the 4D team.
    Sincerly yours

    PmmC version 2.8 will be released some time this week.

    A solution to your requirement is included.

    The SSD1963_SET_ADDRESS_MODE register (0x36) may be written to prior to the next gfx_Cls function, and then the new register value (& 0x08) will stick.

    Note that only the RGB / BGR bit is read, the other register bits are of course manipulated with the gfx_ScreenMode function and will change automatically.

    We've decided to 'enhance' the PmmC rather than create a custom one

    HI,

    Thank you very much, that will solve (I hope ) my problem ...
    Can you please, give me the cost for this custom PmmC before you make it?


    Best regards

    We'll try and have a custom PmmC for you early next week

    Sorry, I found out after I posted that GFX2 was more complicated, so I edited my post.



    We will discuss this (custom PmmC) tomorrow and get back to you.

    ???
    Sorry have received a message wich is not the same as in the forum ???

    So, yes, I've tryed to change the 0x36 SSD register from 0x08 to 0x00, in a 4DGL program, and yes it works , but not very well, (see my previous posts), can be used for drawings?? , but not for images.

    You said that for the GFX2, it's more complicated, can you devellop ?
    I'm familiar with electronics and programmation (30 years experience), so ....

    In the final, if there is no simple issue, can you tell me if I can ask 4D systems for a custom PmmC file, and where should I ask for it ?

    Thanks

    Olivier

    Thanks for the reply,
    Yes, changing the circuit layout is an issue, but needs to re-route the board, and have prototypes of the panel board (TFT + SSD1963) on the hand ....

    I'll use the GFX2 PICASO, but have made investigations with the SGC one, to determine where the problem was, but the final product will use the GFX2.

    [ Forget the SGC workaround, as I'll don't use it ]


    So, if I understand well, using :

    disp_SetReg(Set_Address_Mode command [ who's Hex code is 0x36], 0x3E)
    in the initialization section of any 4DGL program
    will fix the problem as I don't alter the orientation of the display ?


    This is a great new, I'll try and leave you feedback ASAP.


    Thanks a lot for your products and your support.

    Maybe, probably, sorry.



    Why didn't you just fix your circuit board, seems like the easiest and best solution, for you?



    It is not possible from your post to work out whether you are using GFX2 or SGC, you use both words in your posts.



    If you look at the chip documentation you will see that all you need to do is change the value written using the Set_Address_Mode command. For SGC the Parameter needs to be changed from 0x08 to 0x00 (For GFX2 it's more complicated)



    So all you need to do is load the header file into DISP, change the value in the 'defines' tab and save it to the Picaso chip.



    But really, you should fix the board.

    Hello 4D team,

    I wonder if you have forgot me ?
    As I explain in my posts, I need a custom PmmC file ( or any workaround ) for my SSD1963 4.3" LCD, as the PmmC file you use in your 4.3" LCD have RED and BLUE channels inverted via the routing of your pcb.

    How can I have a custom PmmC file ? And is it possible ?And what is the cost of a PmmC custom file ?
    Please let me know your answer, as I'm develloping a product wich will use your Picaso GFX2 chip, and my developing phase is still in standby, waiting for an issue
    from your company.

    Best regards

    Olivier

    Atilla,

    Do you have some solutions for my SSD1963 LCD red and blue colors inverted ?

    Thank you for your response.
