I wanted a high resolution graphics mode that would work on my 8.4" TFT LCD monitor - which can only sync to 640x480. Since the propeller does not have enough memory for a bitmap that size, I decided to modify the 512x384 driver to make a 640x240 bitmap mode.  I also modified the color tiles to be 32x16 so that the color blocks appear square on the monitor.

Memory usage:

  • 4,800 longs for the bitmap
  • 300 words for the color map

As this is only a minor mod of the Parallax driver, the copyright ofcourse stays with Parallax! 

Enjoy!Billhttp://www.mikronauts.com
