STM32H563 SPI LCD display interface

[PFlor.2]

I am trying to interface a STM32H563 to an LCD using the ST7789v controller over SPI.

To test I'm just sending the LCD initialization as specified by the datasheet shown below...

Which I can confirm all this SPI data with a oscilloscope decoder for SPI.  Then I just try to fill the 240x320 screen with red....

HAL_Delay(500);

ST7789v_Fill_Color(0xF800); // Fill with Red.

void ST7789v_SetWindow(uint16_t start_x, uint16_t start_y, uint16_t end_x, uint16_t end_y)

{

// Set Window

LCD_WR_REG(ST7789_CMD_CASET);

LCD_WR_DATA(start_x >> 8);

LCD_WR_DATA(0xFF & start_x);

LCD_WR_DATA(end_x >> 8);

LCD_WR_DATA(0xFF & end_x);

LCD_WR_REG(ST7789_CMD_RASET);

LCD_WR_DATA(start_y >> 8);

LCD_WR_DATA(0xFF & start_y);

LCD_WR_DATA(end_y >> 8);

LCD_WR_DATA(0xFF & end_y);

}

void ST7789v_Fill_Color(uint16_t color)

{

uint16_t i;

ST7789v_SetWindow(0, 0, ST7789_WIDTH - 1, ST7789_HEIGHT - 1);

uint16_t j;

for (i = 0; i < ST7789_WIDTH; i++) {

for (j = 0; j < ST7789_HEIGHT; j++) {

LCD_WR_DATA(color >> 8);

LCD_WR_DATA(color & 0xFF);

}

}

CS_L();

}

but do not see any change...just white display.

I've attached SPI .ioc configuration...any ideas what I'm missing?  Also attached shows MOSI and D/C signal lines

Thanks!
