    Smile Controlling a VGA Monitor

    I was looking on this site and and its shows how to control a monitor with a PIC mirocontroller. However, it is in ASM. Anyone know where I can find this in PICBASIC or how I can translate it?

    Here is the link

    Thanks

    Default You need tight timings

    Hi,

    To display video on a VGA monitor is relatively easy as against composite video since your RGB channels are independent. However it needs solid timing and fast code for the generation of the sync pulses it might not be possible to do it in entirely PBP. Thus asm is possibily the only answer. With the newer PICs like the PIC24 (not supported by PBP) use of the DMA makes it possible to generate QVGA on a graphics LCD using C30. Look for the appnote on the microchip website.
