Figure 35. SDRAM initialization
The SDRAM external memory must be initialized before the GUI initialization to allow its use
as LCD layers frame buffer.
The SDRAM is used also as DCMI output for camera module. The camera output is stored
in camera frame buffer address as 16 bpp (RGB565) and converted to 24 bpp in the
Camera converted frame before its stocking in the selected storage unit.
5.4.2
Touch screen configuration
The touch screen is controlled by:
•
the BSP TS driver that uses the BSP IO driver in case of STM32429-EVAL,
STM32446E-EVAL, STM32F479I-EVAL and STM32F469I-DISCO boards
•
the TS3510 component in case of STM32439-EVAL board
•
the ft6x06 component in case of STM32414G-DISCO board.
