Has anyone used DMA with SPI to help with OLED display write speeds?
I am using a MEGA with a 1351 128x96 OLED.
The fill speeds in the standard libraries are slow and although I have found a few examples of speed boot functions in modified libraries they don't seem to be compatible.
Just trying to find ways to get a faster screen refresh.
Has anyone used DMA with SPI to help with OLED display write speeds?
I am using a MEGA with a 1351 128x96 OLED.
The Arduino MEGA does not have a DMA controller...
(Due and Zero do. The XMega AVR chips have DMA, but no arduino support.)
So is there any other way to speed up the OLED?. I am new to all this and have seen examples of fast graphics but my example of just writing numbers just flickers about every 1/2 second.
