Hi there,
I'm putting together a project that will use a 256x64 OLED using an SSD1322 controller, and achieving a smooth display refresh rate (30Hz or better) is of highest importance. I'm prototyping with a Teensy 3.1 but am considering the 3.5 or 3.6 down the line. The SSD1322 has 3- and 4-wire SPI, 6800 parallel, and 8080 parallel interface options, and I'm wondering which one would be the fastest?
I know that theoretically the parallel interfaces should be quicker, but I read the blog posts about the Teensy's hardware SPI capabilities and dedicated FIFOs and saw the impressive videos showing how fast that can be -- so now I'm wondering whether the SPI might be faster, since (in my understanding) the parallel interface would have to be driven in software.
For the record, I'm aiming to use the u8g2 library to handle the graphics.
Any tips? Thanks!
