Description

At the moment only the #define LCD_FTDI_VM800B35A is supported.
Both Display does work with a FT800 Chip. But the 35A has a 3,5 inch display with a resolution 320 x 240 (QVGA) and the B43 480 x 272 (WQVGA).
I was thinking it is enough to change the resolution to 480 x 272 in the Board.h.
i tried also to use it with some of these display but it is every time the same issue.

  • //#define LCD_FTDI_VM800B35A // FTDI 3.5" with FT800 (320x240)
  • //#define LCD_4DSYSTEMS_4DLCD_FT843 // 4D Systems 4.3" (480x272)
  • //#define LCD_HAOYU_FT800CB // Haoyu with 4.3" or 5" (480x272)
  • //#define LCD_HAOYU_FT810CB // Haoyu with 5" (800x480)
  • //#define LCD_ALEPHOBJECTS_CLCD_UI // Aleph Objects Color LCD UI

i tested the display with a arduino mega and a libary from ftdi the display does defenitv work.
if i disconnect the the MISO Pin while booting there comes the message Release to begin screen calibration and with MISO Pin connected the Backround of the Screen is green and there is green rectangle. maybe that is a resolution error

Maybe somebody have the experience to find what also should be changed that the display works.
Many thanks in forwards

VM800B43 is compatible only have to change the resolution to #define TOUCH_UI_480x272 in config.adv and constexpr uint8_t Swizzle from 2 to zero
