1.7 -The VGAPIC32 project provides software and circuit information to generate an
1.8 -analogue VGA signal from a PIC32 microcontroller. More details can be found in

1.15 +This example demonstrates the generation of an analogue VGA signal from a
1.16 +PIC32 microcontroller using general output pins. It follows on from the work
1.17 +done in the VGAPIC32 project. The result is not entirely satisfactory:

1.24 + artefact of the DMA transfer mechanism.

1.32 +It might be possible introduce some kind of delay and even out the pixel
1.33 +widths, but this has not been investigated. However, unlike the vga-pmp
1.34 +example, there is no accompanying signal to potentially orchestrate the
1.35 +staging of individual pixels at a slightly delayed rate.
