Скачать или смотреть ILI9341 with DMA and Optimization -O1

Just a short video with the latest library for the ILI9341 to be used on the SBMS100 project.
As you seen in my last video this test was taking 84.326 seconds no DMA and no Optimization (I used Optimization None -O0) and if I add Optimization Level -O1 I can get the same library without DMA at 47.207 seconds (that is really great).
Adding DMA without optimization -O0 gets the test done in 49.150 seconds while adding -O1 to the DMA version gets 33.712 as you see in this video.
Compared to original library this is about 30x faster and now really as good as it can get at 40MHz CPU and 20MHz SPI.
SPI is full there is nothing more to optimize at this point.
