Function esp_idf_sys::esp_lcd_panel_io_tx_color

pub unsafe extern "C" fn esp_lcd_panel_io_tx_color(

    color: *const c_void,

@brief Transmit LCD RGB data

@note This function will package the command and RGB data into a transaction, and push into a queue. The real transmission is performed in the background (DMA+interrupt). The caller should take care of the lifecycle of the color buffer. Recycling of color buffer should be done in the callback on_color_trans_done().

@param[in] io LCD panel IO handle, which is created by factory API like esp_lcd_new_panel_io_spi() @param[in] lcd_cmd The specific LCD command, set to -1 if no command needed @param[in] color Buffer that holds the RGB color data @param[in] color_size Size of color in memory, in bytes @return - ESP_ERR_INVALID_ARG if parameter is invalid - ESP_OK on success
