/* The timings need to follow the datasheet for your particular TFT/LCD screen (the actual screen, not the controller)
|
|
|
|
|
*** Datasheets normally use a specific set of timings and acronyms, their value refers to the number of pixel clocks
|
|
|
|
|
** Non-display periods refer to pulses/timings that occur before or after the timings that actually put pixels on the screen
|
|
|
|
|
** Display periods refer to pulses/timings that directly put pixels on the screen
|
|
|
|
|
HDP: Horizontal Display Period, normally the width - 1
|
|
|
|
|
HT: Horizontal Total period (display + non-display)
|
|
|
|
|
HPS: non-display period between the start of the horizontal sync (LLINE) signal and the first display data
|
|
|
|
|
LPS: horizontal sync pulse (LLINE) start location in pixel clocks
|
|
|
|
|
HPW: Horizontal sync Pulse Width
|
|
|
|
|
VDP: Vertical Display period, normally height - 1
|
|
|
|
|
VT: Vertical Total period (display + non-display)
|
|
|
|
|
VPS: non-display period in lines between the start of the frame and the first display data in number of lines
|
|
|
|
|
FPS: vertical sync pulse (LFRAME) start location in lines.
|
|
|
|
|
VPW: Vertical sync Pulse Width
|

|
