STM32F429 Custom TFT Board With 4.3" TFT

Caan · ‎2025-01-24

I have designed a STM32F429 Custom TFT Board With 4.3" TFT it is based on 32F429IDISCOVERY MCU + RAM + 4.3" TFT in 16 bit mode and I'm using TouchGFX.

I have few questions.
1) It is possible to remove External RAM from the System.
2) How to limit RAM Usage so as to use the internal MCU RAM only

Ok. Need to tell that in the first post because the answer may differ and your question could be generic not specific (related to TouchGFX).

I'm editing it then ..

I did specified that " I have designed a STM32F429 Custom TFT Board With 4.3" TFT it is based on 32F429IDISCOVERY MCU + RAM + 4.3" TFT in 16 bit mode and I'm using TouchGFX ".
I would like to know your thoughts on using internal RAM as Frame buffer.
