Hi Ti,
follow VESA spec, we hope get hsync and vsync relationship as below
we hope Vsync rises when Hsync rises, but measure wave frame get Vsync rises when Hsync falls as below
My configure setting is
static struct lcd_ctrl_config lcd_cfg = {
&disp_panel,
.ac_bias = 255,
.ac_bias_intrpt = 0,
.dma_burst_sz = 16,
.bpp = 32,
.fdd = 0x80,
.tft_alt_mode = 0,
.stn_565_mode = 0,
.mono_8bit_mode = 0,
// .invert_line_clock = 1,
// .invert_frm_clock = 1,
.invert_line_clock = 0,
.invert_frm_clock = 0,
.sync_edge = 0,
.sync_ctrl = 1,
.raster_order = 0,
};
How can I modify to meet my request? thanks
