I am interfacing to a 320x240 pixel TFT with a Himax HX8238-A controller.
I have difficulties understanding the timing relationships between
VSYNC, HSYNC and DOTCLOCK.
One problem concerns the vertical and horizontal front/back porches.
What signals are needed here?
I have AN3493, which is helpful but not detailed enough when
it comes to timing issues.
All comments and pointers to litterature are most welcome.
