However, it is important to remember that these are starting points. Fine-tuning orientation and color order is almost always required based on the specific PCB layout of your display module.
When working with TFT LCD displays (such as those driven by ILI9341, ST7735, or ILI9486 controllers), one of the biggest hurdles for beginners is initializing the screen. Without the correct initialization sequence, the screen will remain white, black, or display random noise.

void LCD_WR_DATA(uint8_t data) { LCD_CS_LOW; LCD_DC_HIGH; // DC High = Data HAL_SPI_Transmit(&hspi1, &data, 1, 100); LCD_CS_HIGH; } In your main application loop, call the generated function before attempting to draw pixels.
