Reference boards with LCD-TFT panel

ST offers a wide range of reference boards such as NUCLEO, Discovery and EVAL boards,

many of them embedding display panels. For STM32 reference boards featuring an on-

board display but not embedding an LTDC, the DBI (FMC or SPI) interface is used to

connect the STM32 with the display.

For the other STM32 boards, the LTDC is used to interface with the display panel.

These reference boards can be used to evaluate the graphic capability in specific hardware

/ software configurations.

Table 17 summarizes the STM32 reference boards embedding LTDC and featuring an on-

board TFT-LCD panel.
