Functions

lv_display_t *lv_st_ltdc_create_direct(void *fb_adr_1, void *fb_adr_2, uint32_t layer_idx)

Create a direct render mode display bound to a LTDC layer.

参数:

  • fb_adr_1 -- The LTDC layer's framebuffer memory address.

  • fb_adr_2 -- An additional framebuffer-sized buffer to use for double buffering, or NULL.

  • layer_idx -- The LTDC layer number to bind the display to. Typically 0 or 1.

返回:

The display.

lv_display_t *lv_st_ltdc_create_partial(void *render_buf_1, void *render_buf_2, uint32_t buf_size, uint32_t layer_idx)

Create a partial render mode display bound to a LTDC layer. The layer's framebuffer is flushed to internally. Enable LV_ST_LTDC_USE_DMA2D_FLUSH for parallel flushing.

参数:

  • render_buf_1 -- A render buffer.

  • render_buf_2 -- An additional render buffer for double-buffering, or NULL.

  • buf_size -- The size of the buffer(s) in bytes.

  • layer_idx -- The LTDC layer number to bind the display to. Typically 0 or 1.

返回:

The display.
