  1. I am developing ugfx_2.9 for a DIY product. Keil uVision is used and the main MCU is nRF52840. 1. The display uses E-ink's ET011TJ2. Is the driver IC correct for UC8173? 2. However, g->priv = 0 in the initialization function of <gdisp_lld_UC8173.c> as follows. So return gFalse; proceed with As a result, the initialization routine does not proceed. sizeof(UC8173_Private) = 14412 How can I initialize normally? 3. I tried changing HESP_SIZE in various ways as follows. But in all cases g->priv = 0 . #define GFX_OS_HEAP_SIZE 14412 //0 //4095 //20480 // 30720 //10240 //10240 //40960 4. I have set it up like this: #define GFX_EMULATE_MALLOC GFXON Still, g->priv = 0. Since g->priv = 0 unconditionally, the initialization function cannot proceed. How to solve it? <gfxconf.h> /////////////////////////////////////////////////////////////////////////// // GOS - One of these must be defined, preferably in your Makefile // /////////////////////////////////////////////////////////////////////////// //#define GFX_USE_OS_CHIBIOS GFXOFF //#define GFX_USE_OS_FREERTOS GFXOFF // #define GFX_FREERTOS_USE_TRACE GFXOFF //#define GFX_USE_OS_WIN32 GFXOFF //#define GFX_USE_OS_LINUX GFXOFF //#define GFX_USE_OS_OSX GFXOFF //#define GFX_USE_OS_ECOS GFXOFF //#define GFX_USE_OS_RAWRTOS GFXOFF //#define GFX_USE_OS_ARDUINO GFXOFF //#define GFX_USE_OS_KEIL GFXON //#define GFX_USE_OS_RTX5 GFXOFF #define GFX_USE_OS_CMSIS GFXON <<<======= //#define GFX_USE_OS_CMSIS2 GFXOFF //#define GFX_USE_OS_RAW32 GFXOFF //#define GFX_USE_OS_ZEPHYR GFXOFF //#define GFX_USE_OS_NIOS GFXOFF //#define GFX_USE_OS_QT GFXOFF // #define INTERRUPTS_OFF() optional_code // #define INTERRUPTS_ON() optional_code // Options that (should where relevant) apply to all operating systems // #define GFX_NO_INLINE GFXOFF // #define GFX_COMPILER GFX_COMPILER_UNKNOWN // #define GFX_SHOW_COMPILER GFXOFF // #define GFX_CPU GFX_CPU_UNKNOWN // #define GFX_CPU_NO_ALIGNMENT_FAULTS GFXOFF // #define GFX_CPU_ENDIAN GFX_CPU_ENDIAN_UNKNOWN #define GFX_OS_HEAP_SIZE 14412 //0 //4095 //20480 // 30720 //10240 //10240 //40960 <<<======= // #define GFX_OS_NO_INIT GFXOFF // #define GFX_OS_INIT_NO_WARNING GFXOFF // #define GFX_OS_PRE_INIT_FUNCTION myHardwareInitRoutine // #define GFX_OS_EXTRA_INIT_FUNCTION myOSInitRoutine // #define GFX_OS_EXTRA_DEINIT_FUNCTION myOSDeInitRoutine // #define GFX_OS_CALL_UGFXMAIN GFXOFF // #define GFX_OS_UGFXMAIN_STACKSIZE 0 // #define GFX_EMULATE_MALLOC GFXON <<<======= // #define GFX_MEM_LT64K GFXOFF <gdisp_lld_UC8173.c> LLDSPEC gBool gdisp_lld_init(GDisplay* g) { UC8173_Private *priv; printf("UC8173:gdisp_lld_init - 1 HEAP = %d\r\n", GFX_OS_HEAP_SIZE); // Allocate the private area g->priv = gfxAlloc(sizeof(UC8173_Private)); <<<======= printf("UC8173:gdisp_lld_init - 2 memAlloc = %d, sz = %d\r\n", g->priv, sizeof(UC8173_Private)); <<<======= if (!g->priv) return gFalse; priv = (UC8173_Private *)g->priv; gfxconf.h
