Free graphics display designer tool for PICs

MicrochipRTCfr

Looking for faster & free embedded GUI design ?

 

The Graphics Display Designer tool enables graphical design of the user interface and generates C code which can be directly compiled into libray calls using the free Microchip compilers.

Code can then be tested using the Graphics development kits based on PIC24F/H, dsPIC33 or PIC32 processors.

For highest integration, PIC24F family with on-chip graphics LCD controller can be used and developed with the new PIC24FJ256DA210 Development Kit

  • Dear Sir or Madam,

     

    I'am new in Microchip graphic library and I have one  question. If I would use a PIC24FJ256DA210, according to the datasheet  it is possible to achieve a resolution of 640x480 with 16bpp. This ist  only achievable with further external SDRAM.

     

    I have read in the description of the graphic library that:

    "The Microchip graphics library supports the following features:

    Up to 480x272 (WQVGA) resolution
    Up to 16-bit or 65K colors"

     

    Is  that the limitions of the graphic library (480x272) or is it possible  to design a window with a larger resolution like 640x480 or 800x480?

    I read in chat room that a larger resolution should be possible. It's a little confused!

     

    best regards

    Hi,

     

    You should not confuse the chip capabilities and the graphics libraries specification.

    As far as the PIC24FJ256DA210 microcontroller is concerned, the specification clearly states :

    "Resolution up to 640x480 @30Hz, 16 bpp, or 480x272 @60Hz, 16 bpp"
    So VGA is achievable but with @30Hz / 16bpp because the controller is at the limit of its throughput.
     
    Even though there is no project example yet in the graphics libraries using VGA, they are not limited in resolution.
    In fact I believe that a Pictail plus board with a VGA display is in preparation and should be available in 2011 from Microchip.
    There is a dedicated forum for graphics libraries questions here.
     
    The external memory is not SDRAM but standard SRAM. You can find the schematics of the graphics display board in the graphics demoboard user manual
