Title: How to upload raw image into vram of FT8000
Post by: PK_hweng on November 20, 2019, 08:31:23 PM

Hi,

I try to upload some RAW graphic files to the GRAM of the FT800.
It is some old project that needs a gui update. Until now I had only one jpeg sucessfully loaded with CMD_LOADIMAGE, this works but now I need to place several graphics in raw (RGB565) format.

When using a jpeg there is the load_image command before loading the file into the command buffer.
But I can't find any command for raw :(

The commands to handle the image when its already in the ram are quite clear to me:

Ft_App_WrCoCmd_Buffer(disp_host, BEGIN(BITMAPS));
Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_HANDLE(id));
Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_SOURCE(RAM_G + offset));
Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_LAYOUT(RGB565, 100, 50));
Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_SIZE(NEAREST, BORDER, BORDER, 100, 50));
Ft_App_WrCoCmd_Buffer(disp_host, VERTEX2II(0, 0, id, 0));

But how do I put the bitmap to the position (RAM_G + offset) in VRAM?

I had tryed Ft_Gpu_Hal_WrMem(phost, (RAM_G + Offset), ....) but it doesn't work.

I will be grateful for any advice!

Best regards,
Philipp

I have found the solution  8) :

Code: [Select]

Ft_Gpu_CoCmd_MemWrite(disp_host, RAM_G+Offset, fileSize); // EVE upload with the filesize initialize

while()
{
...
Ft_Gpu_Hal_WrCmdBuf(phost, imageBuffer, blockLen); // write data in the command buffer
...
}

// END COPY FILE TO EVE
    Ft_App_WrCoCmd_Buffer(disp_host, BEGIN(BITMAPS));
    Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_HANDLE(0));
    Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_SOURCE(RAM_G+Offset));
    Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_LAYOUT(RGB565, 100*2, 50));
    Ft_App_WrCoCmd_Buffer(disp_host, BITMAP_SIZE(NEAREST, BORDER, BORDER, 100, 50));
    Ft_App_WrCoCmd_Buffer(disp_host, VERTEX2II(0, 0, 0, 0));
    Ft_App_WrCoCmd_Buffer(disp_host, END());

And to repeat myself here, you were actually looking for cmd_inflate(). :)
