Can I customize the Project and LCD on board STM32F429I-DISC1 to use other LCD?

I have studied using the STM32F429I-DISC1 board with TouchGFX and can already implement buttons, LEDs, and ADC. However, I have a project that requires using a different LCD that uses the SSD2119. Can I directly replace the LCD, or are there additional parts of the code that need to be modified? Please guide me.

Hello @NakornThree.

Which display interface are you planning to use?

It looks like your selected display does not support parallel RGB interface, which is what the TBS available in TouchGFX Designer is configured for. Therefore, you cannot directly replace the display with the current TBS setup.
However, TouchGFX Designer includes TBS examples demonstrating both 8080 and 4-wire SPI display interfaces. I recommend reviewing these examples if you decide to use one of those interfaces.

Best regards,
Johan
