怎么从外部闪存写入TFT_LCD

我有2个配置：-TFT，带有控制器（SSD1963）的480X222像素。带控制器的800×480像素的TFT（SSD1963）。480X22使用PIC32 MZ，I可以从外部闪存读取RAM并写入LCD，因为PIC32 MZ具有512K字节的RAM，全屏需要261120字节，但具有800×480。它需要768000个字节，那么什么是优化速度的最佳方法？1。-读取半字节（384000）并写入TFT，然后读取剩余的384000个字节并再次写入TFT。2。-从FLASH读取1个像素并写入TFT循环，直到完成全屏。也许还有另一种方法比这2最佳。感谢任何帮助。

    I have 2 configs:

- TFT with 480x272 pixels with controller (SSD1963).
- TFT with 800x480 pixels with controller (SSD1963).

With the 480x272 using a PIC32MZ I can read from external flash to RAM and write to LCD because PIC32MZ has 512Kbyte of RAM and a full screen needs 261120 bytes, but with 800x480 it needs 768000 bytes so what could be the best method for optimized speed?

1.- Read half of bytes(384000) and write to TFT then read the rest 384000 bytes and write again to TFT.
2.- Read 1 pixel from flash and write to TFT cyclic until full screen is done.

Maybe there is another method that is best than this 2. Any help appreciated.

Thanks.
Francisco.
