About TouchGFX frame buffer problem

TomBrown · ‎2025-11-04

Hello, I'm using TouchGFX on an STM32L452RET6 with an SPI screen. The screen has integrated GRAM, so I selected the partial buffer option in STM32CubeMX. STM32CubeMX generated the partial buffer code as expected, but it also generated code for a full frame buffer, which exceeds the MCU's RAM. I need to comment out this code to reduce RAM usage. How can I prevent STM32CubeMX from generating the full frame buffer code?

STM32CubeMX version: 6.15.0

X-Cube -TouchGFX package and TouchGFX Designer version: 4.25.0

STM32L4 Cube package version: 1.81.1
