Hi,
The result is the same, it has white pixels.
I think the display settings are correct because when a series resistor is connected to VSYNC and HSYNC pins, it displays the screens.
The settings parameters;
#define settingQVGALCDPARAMETER \
{ \
480U, /* Active width of LCD display */ \
272U, /* Active height of LCD display */ \
548U, /* Total number of clocks per line */ \
43U, /* Start of active line */ \
0U, /* Start of horizontal sync pulse */ \
41U, /* End of horizontal sync pulse */ \
292U, /* Total number of lines per screen */ \
12U, /* Start of active screen */ \
0U, /* Start of vertical sync pulse */ \
10U, /* End of vertical sync pulse */ \
5, /* Pixel Clock */ \
0, /* Define RGB output pins */ \
1, /* Define active edge of PCLK */ \
} \
Also, I enclosed the display parameters which in the datasheet of TFT.
