Optimisations for RP2040

Open Bodmer opened this issue 4 years ago • 0 comments

These changes plus a companion pull request for Adafruit_ILI0341provide performance benefits for the RP2040 based boards when used in hardware SPI mode.

I suspect this pull needs to be refactored since SPI code has been introduced in Adafruit_ILI9341 which breaks the partioning with Adafruit_GFX library. Also, although this works with Earle Philhower's Arduino core and calls low level SPI code, it may not be compatible with the "official" Arduino RP2040 core.
