SDRAM capacity used by Touch GFX

[Ebun.1]

Thank you for helping.

How much SDRAM capacity does TouchGFX actually consume?

Please tell me the unit in bytes.

environment

board: STM32F769I-DISCO

TouchGFX: Ver4.15.0

Hi Ebun.1,

If you are using the application template available from TouchGFX Designer for the STM32F769I-disco board, the SDRAM is only used to store framebuffers. For this board, one framebuffer is set at the address 0xC000000. In general the amount of memory used by a framebuffer is equal to: the width * height * color depth in bits / 8 bytes, so in this case : 800*480*16/8 = 768000 bytes
