GD32f50 in (144 feet) can drive. Rgb565 GD32F450I (176 feet) can not only drive rgb65 can drive rgb888,
1. Now I want to choose GD32F450Z (144 feet),
2. My current screen is a LVDSDE vertical screen resolution of 480 * 1280. Check the information GD32 biggest can drive 1028 * 768 resolution,
I want to ask is, if I use GD32F450Z drive rgb565, then use the rgb565 turn an LVDS chip, access to an LVDS screen, then GD32F450 can drive the LCD screen, because the resolution of the two is a little difference, (and this is the vertical screen when the time comes I will need to character flip)



Is there another who knows rgb565 turn an LVDS chip, I found a GM8283. See his input is 18 and 24, didn't write rgb565 16, don't know whether receive rgb565 mode of access

CodePudding user response:

Good thinking, can realize, need to pay attention to a few places
1: check the CPU manual, see if the LCD maximum vertical resolution can meet (greater than 1280, general register number is greater than or equal to 11),
2: RGB565 can direct connection to the RGB666 (18)/RGB888 (24),
3: according to your LCD screen, choose 18/24 of an LVDS chips,
4: need software to do the work, vertical screen to display character flip
