Report STM32F303 and ST7789V with SPI 9 bit. in Support Posted February 23, 2018 Greetings, I am trying to integrate ugfx for my home project based on STM32F303 and ST7789V based LCD Display. ST7789V connected by SPI 9 bit. 1 last extra bit for D/C used. I started the display itself and with raw HAL functions the full fill was working. Now I am trying to integrate UGFX. IDE is Keil. Problem is: By calling gfxInit(); no calls to functions like gdisp_lld_init(GDisplay *g) and others. The display is not initializing. Is it missconfiguration of project/makefiles/include paths or something else? Looking to examples and documentation I wrote board file: #ifndef _GDISP_LLD_BOARD_H #define _GDISP_LLD_BOARD_H static GFXINLINE void setpin_reset(GDisplay *g, bool_t state); static GFXINLINE void init_board(GDisplay *g); static GFXINLINE void write_data(GDisplay *g, uint16_t data); static GFXINLINE void write_index(GDisplay *g, uint16_t data); static GFXINLINE void send_data( uint16_t data); static GFXINLINE void init_board(GDisplay *g) { // As we are not using multiple displays we set g->board to NULL as we don't use it. // g->board = 0; setpin_reset(g, TRUE); HAL_Delay(30); write_index(g, 0x011); HAL_Delay(30); write_index(g, 0x036); write_data(g, 0x000); write_index(g, 0x3A); write_data(g, 0x06); write_index(g, 0xB2); write_data(g, 0x00C); write_data(g, 0x00C); write_data(g, 0x000); write_data(g, 0x033); write_data(g, 0x033); write_index(g, 0xBB); //? write_data(g, 0x1A); //? write_index(g, 0xC0); write_data(g, 0x2C); write_index(g, 0xC2); write_data(g, 0x01); write_index(g, 0xC3); write_data(g, 0x0F); write_index(g, 0xC4); write_data(g, 0x20); write_index(g, 0xC6); write_data(g, 0x0F); write_index(g, 0xD0); write_data(g, 0xA4); write_data(g, 0xA1); write_index(g, 0xE0); write_data(g, 0xD0); write_data(g, 0x13); write_data(g, 0x1A); write_data(g, 0x0A); write_data(g, 0x0A); write_data(g, 0x26); write_data(g, 0x3F); write_data(g, 0x54); write_data(g, 0x54); write_data(g, 0x18); write_data(g, 0x14); write_data(g, 0x14); write_data(g, 0x30); write_data(g, 0x33); write_index(g, 0xE1); write_data(g, 0xD0); write_data(g, 0x13); write_data(g, 0x1A); write_data(g, 0x0A); write_data(g, 0x0A); write_data(g, 0x26); write_data(g, 0x3F); write_data(g, 0x54); write_data(g, 0x54); write_data(g, 0x1A); write_data(g, 0x16); write_data(g, 0x16); write_data(g, 0x32); write_data(g, 0x35); write_index(g, 0x29); HAL_Delay(30); write_index(g, 0x21); write_index(g, 0x2A); write_data(g, 0x00); write_data(g, 0x00); write_data(g, 0x00); write_data(g, 0xEF); write_index(g, 0x2B); write_data(g, 0x00); write_data(g, 0x00); write_data(g, 0x00); write_data(g, 0xEF); } static GFXINLINE void post_init_board(GDisplay *g) { (void) g; } static GFXINLINE void setpin_reset(GDisplay *g, bool_t state) { (void) g; HAL_GPIO_WritePin(GPIOB, GPIO_PIN_14, GPIO_PIN_RESET); HAL_Delay(120); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_14, GPIO_PIN_SET); } static GFXINLINE void set_backlight(GDisplay *g, uint8_t percent) { (void) g; (void) percent; } static GFXINLINE void acquire_bus(GDisplay *g) { (void) g; } static GFXINLINE void release_bus(GDisplay *g) { (void) g; } static GFXINLINE void write_index(GDisplay *g, uint16_t index) { (void) g; HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_RESET); uint16_t DC; DC = index; HAL_SPI_Transmit(&hspi2, (uint8_t *)&DC, 1, 100); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_SET); } static GFXINLINE void send_data( uint16_t data) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_RESET); uint16_t DC; // = 0x0001; DC = data | 0x100; HAL_SPI_Transmit(&hspi2, (uint8_t *)&DC, 1, 100); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_SET); } static GFXINLINE void write_data(GDisplay *g, uint16_t data) { (void) g; send_data(data); } static GFXINLINE void setreadmode(GDisplay *g) { (void) g; } static GFXINLINE void setwritemode(GDisplay *g) { (void) g; } static GFXINLINE uint16_t read_data(GDisplay *g) { (void) g; return 0; } #endif /* _GDISP_LLD_BOARD_H */ My GDISP LLD file: #include "gfx.h" #if GFX_USE_GDISP #if defined(GDISP_SCREEN_HEIGHT) || defined(GDISP_SCREEN_HEIGHT) #if GFX_COMPILER_WARNING_TYPE == GFX_COMPILER_WARNING_DIRECT #warning "GDISP: This low level driver does not support setting a screen size.

STM32F303 and ST7789V with SPI 9 bit.
in Support
Posted
Greetings,
I am trying to integrate ugfx for my home project based on STM32F303 and ST7789V based LCD Display.
ST7789V connected by SPI 9 bit. 1 last extra bit for D/C used.
I started the display itself and with raw HAL functions the full fill was working.
Now I am trying to integrate UGFX. IDE is Keil.
Problem is: By calling gfxInit(); no calls to functions like gdisp_lld_init(GDisplay *g) and others. The display is not initializing.
Is it missconfiguration of project/makefiles/include paths or something else?
Looking to examples and documentation I wrote board file:
