How to transform the picture more than 320x240 pixels. I have a display 480x272 pixels.

[David John Barker]

I have uploaded a new install

which increases the resolution to 640 x 480 pixels.

How to transform the picture more than 320x240 pixels. I have a display 480x272 pixels.

Hi,
Are you using 4.3 inch tFT with a SSD1963 controller?

If yes, I am curious to find out if you have ran it already?

I have one, but still cannot initialize it. Interesting, because I have another tuft 5' with better resolution 800x480 and it runs on the same board.
It also feature the SSD1963...

Ok, would you specify the values of:
Hdp, vdp and so on...

[demanik]

excuse, I forgot
HDP = 479, ' Set HDP
VDP = 271, ' Set VDP
HT = 531, ' Set HT
HPS = 43, ' Set HPS
HPW = 10, ' Set HPW
LPS = 8, ' Set LPS
VT = 288, ' Set VT
VPS = 12, ' Set VPS
VPW = 10, ' Set VPW
FPS = 4 ' Set FPS

Still nothing TFT doesn't initialize. Any other suggestions? Tips & Hints?
