[Original] [serialization]. Simple Digital Photo Frame Based on the System-nioii sbte part (software part)-Optimization

In the previous article, although the image in the SD card has been displayed, the speed is not ideal. Therefore, a certain degree of optimization is required. In the ili9325 driver blog, I want to minimize the number of repeated changes in the direction of the Data Bus, chip selection switch, and so on. However, these are just a drop in the water and we still need to do more optimization. There are many optimization ideas. Now we only introduce one of the most direct ways: Disable the debugging level option and set the optimization level to level 3. Shows the settings.

It should be noted that the optimization settings have certain risks. We must go through repeated debugging to achieve the best results. After the above optimization, we can obviously feel that the screen flushing speed has become faster.

 

It is a pity that there is still great potential for improving the performance of the niosii soft core.
