I am using STM32F769I-Disco with LCD(BLCD40-DSI) and trying to get the initialization code of the LCD but am unable to get it. Please someone can let me know where I can get it.

Try install TouchGFX designer create example for Disco and in BSP folder ...

Hi Thank You, I got the c code but do you know why they include HDMI things because it is not connected through HDMI and has no HDMI connections.

The board comes in versions with and without the screen.

There is a board available which converts to HDMI, and that can be used in-place of the screen. It uses an ADV7533 chip.

Check the README.TXT files, there are build options for BOTH cases, use the one using the OTM8009 and the KoD LCD

Make sure USE_LCD_HDMI is **NOT** defined, on the command line or within the project

Thank you for response. So, it is for optional purpose right?

where I can find Readme.txt file?

[Tesla DeLorean · Accepted solution]

The README.TXT usually lives in the top level project directories, explaining usage, etc

Current code is supposed to auto-detect screen

STM32Cube_FW_F7_V1.17.0\Projects\STM32F769I-Discovery\Examples\JPEG\JPEG_DecodingUsingFs_DMA\readme.txt

Pretty sure you can find references in the code to USE_LCD_HDMI, grep..

The boards without the screen was an actual product
