  1. Hi There, I know that there are quite a handful of other topics out there that talk about the same Problem. But somehow, I could not find a solution for me yet. For a few days I have been trying to get ugfx together with chibios and the STM32F429i to work. But so far nothing worked out for me. I found some older projects that actually worked with older ChibiOS Versions, but for the newer Version i never got it to actually display something. I use, ChibiOS-version 18.2.1 and I would like to use the up to date ugfx Version that i pulled from there: https://git.ugfx.io/uGFX/uGFX Then I basically tried to modify this example https://community.ugfx.io/files/file/22-stm32f429i-discovery-with-chibios-using-chibistudio/ to get it to work with the newer ugfx version. It would be nice if someone could share a running minimalistic setup... Otherwise, this is the compiler errors I get when compiling: In file included from ../ugfx/boards/base/STM32F429i-Discovery/chibios/stm32f429i_discovery_sdram.c:4:0: ../ugfx/boards/base/STM32F429i-Discovery/chibios/stm32f429i_discovery_sdram.h:89:25: error: unknown type name 'gU32' void SDRAM_WriteBuffer(gU32* pBuffer, gU32 uwWriteAddress, gU32 uwBufferSize); and before that I also receive some warnings: In file included from ../ugfx/src/gtrans/../../src/gfx.h:148:0, from ../ugfx/src/gtrans/../../gfx.h:7, from ../ugfx/src/gtrans/gtrans.c:9: ../ugfx/src/gtrans/../../src/gdisp/gdisp_rules.h:69:7: warning: "GDISP_HARDWARE_PIXELREAD" is not defined, evaluates to 0 [-Wundef] #if GDISP_HARDWARE_PIXELREAD Thanks for your help Greetings Kisle
