  1. it seems i have problem in “ RAM(g)[xyaddr(x, y)] &= ~xybit(y) ; ” because when I use keil bebug and running at this code,the mcu will goto“ void HardFault_Handler(void)” but I think the really problem is “ g->priv = gfxAlloc() ” yes that function. my configuration are : //#define GFX_USE_OS_WIN32 FALSE //#define GFX_USE_OS_LINUX FALSE //#define GFX_USE_OS_OSX FALSE //#define GFX_USE_OS_ECOS FALSE //#define GFX_USE_OS_RAWRTOS FALSE //#define GFX_USE_OS_ARDUINO FALSE //#define GFX_USE_OS_KEIL FALSE //#define GFX_USE_OS_CMSIS FALSE #define GFX_USE_OS_RAW32 TRUE //#define GFX_USE_OS_NIOS FALSE //#define GFX_USE_OS_QT FALSE // #define INTERRUPTS_OFF() optional_co // #define INTERRUPTS_ON() optional_co // Options that (should where relevant) apply to all operating sys // #define GFX_NO_INLINE FALSE #define GFX_COMPILER GFX_COMPILER // #define GFX_SHOW_COMPILER FALSE // #define GFX_CPU GFX_CPU_UNK // #define GFX_CPU_NO_ALIGNMENT_FAULTS FALSE // #define GFX_CPU_ENDIAN GFX_CPU_END // #define GFX_OS_HEAP_SIZE 0 // #define GFX_OS_NO_INIT FALSE // #define GFX_OS_INIT_NO_WARNING FALSE // #define GFX_OS_PRE_INIT_FUNCTION myHardwareI // #define GFX_OS_EXTRA_INIT_FUNCTION myOSInitRou // #define GFX_OS_EXTRA_DEINIT_FUNCTION myOSDeInitR // #define GFX_EMULATE_MALLOC TRUE so i dont know how to usb the gfxAlloc()
  2. It seems be stuck at the _gdispInit(); function.
  3. Hardware : NUCLEO-F302R8 library: STM32-CUBEMX, uGFX 2.7 compiler:KEIL MDK 5.2 I try to interated to my board,it can pass compile, when I use oled own dirver,it can work, but the ugfx do not work, i think i have something wrong in the configuration.any boby help? thx uGFX_OLED.zip
  4. oh,I make the mistake that I use the old version.then I trying the latest library. thanks Joel
  5. I use keil MDK 5.23 to build the project and my board is STM32F429 DISC. I can build the demo successfully ,but when I try to make a "hello word " case ,I use uGFX-Studio to generate the code,and copy to my project,unfortunately I met the error "..\widgetstyles.h(30): error: #146: too many initializer values",why ?how can i work out?
  6. I see,thank you! Now I'm trying to use it
  7. I'm new of uGFX,I have uGFX working in my STM32F429 DISCOVERY , and I want to use the uGFX-Studio to do something ?Are there some documents to help me learn to use it? thx
