Color input format of HAL_DMA2D_Start()

[ShadowLee]

What should be the color input format for hal_dma2d_start()?
According to the function definition, it seems that only ARGB8888 format colors can be inputted.

static void DMA2D_SetConfig(DMA2D_HandleTypeDef *hdma2d, uint32_t pdata, uint32_t DstAddress, uint32_t Width,
                            uint32_t Height)
{
  uint32_t tmp;
  uint32_t tmp1;
  uint32_t tmp2;
  uint32_t tmp3;
  uint32_t tmp4;

  /* Configure DMA2D data size */
  MODIFY_REG(hdma2d->Instance->NLR, (DMA2D_NLR_NL | DMA2D_NLR_PL), (Height | (Width << DMA2D_NLR_PL_Pos)));

  /* Configure DMA2D destination address */
  WRITE_REG(hdma2d->Instance->OMAR, DstAddress);

  /* Register to memory DMA2D mode selected */
  if (hdma2d->Init.Mode == DMA2D_R2M)
  {
    tmp1 = pdata & DMA2D_OCOLR_ALPHA_1;
    tmp2 = pdata & DMA2D_OCOLR_RED_1;
    tmp3 = pdata & DMA2D_OCOLR_GREEN_1;
    tmp4 = pdata & DMA2D_OCOLR_BLUE_1;

    /* Prepare the value to be written to the OCOLR register according to the color mode */
    if (hdma2d->Init.ColorMode == DMA2D_OUTPUT_ARGB8888)
    {
      tmp = (tmp3 | tmp2 | tmp1 | tmp4);
    }
    else if (hdma2d->Init.ColorMode == DMA2D_OUTPUT_RGB888)
    {
      tmp = (tmp3 | tmp2 | tmp4);
    }
    else if (hdma2d->Init.ColorMode == DMA2D_OUTPUT_RGB565)
    {
      tmp2 = (tmp2 >> 19U);
      tmp3 = (tmp3 >> 10U);
      tmp4 = (tmp4 >> 3U);
      tmp  = ((tmp3 << 5U) | (tmp2 << 11U) | tmp4);
    }
    else if (hdma2d->Init.ColorMode == DMA2D_OUTPUT_ARGB1555)
    {
      tmp1 = (tmp1 >> 31U);
      tmp2 = (tmp2 >> 19U);
      tmp3 = (tmp3 >> 11U);
      tmp4 = (tmp4 >> 3U);
      tmp  = ((tmp3 << 5U) | (tmp2 << 10U) | (tmp1 << 15U) | tmp4);
    }
    else /* Dhdma2d->Init.ColorMode = DMA2D_OUTPUT_ARGB4444 */
    {
      tmp1 = (tmp1 >> 28U);
      tmp2 = (tmp2 >> 20U);
      tmp3 = (tmp3 >> 12U);
      tmp4 = (tmp4 >> 4U);
      tmp  = ((tmp3 << 4U) | (tmp2 << 8U) | (tmp1 << 12U) | tmp4);
    }
    /* Write to DMA2D OCOLR register */
    WRITE_REG(hdma2d->Instance->OCOLR, tmp);
  }
  else /* M2M, M2M_PFC or M2M_Blending DMA2D Mode */
  {
    /* Configure DMA2D source address */
    WRITE_REG(hdma2d->Instance->FGMAR, pdata);
  }
}

 But in stm32f429xx.h,  I can see some marco definitions for other colors input format. It seems that the input color format of HAL_DMA2D_Start() can be changed to RGB565 or something else, but there is no such a option in HAL_DMA2D_Start().
