Expand description

@brief Allocate a draw buffer that can be used by I80 interfaced LCD panel

@note This function differs from the normal ‘heap_caps_*’ functions in that it can also automatically handle the alignment required by DMA burst, cache line size, etc.

@param[in] io Panel IO handle, created by esp_lcd_new_panel_io_i80() @param[in] size Size of memory to be allocated @param[in] caps Bitwise OR of MALLOC_CAP_* flags indicating the type of memory desired for the allocation @return Pointer to a new buffer of size ‘size’ with capabilities ‘caps’, or NULL if allocation failed
