If you try to compile a Sketch for ATSAMD21 Boards like Arduino Zero or Feather M0 it will Exit with an Error like:

In file included from /home/USER/Arduino/Game/v1/base_w_pdq/base_w_pdq.ino:38:0: /home/USER/Arduino/libraries/PDQ_ST7735/PDQ_ST7735.h:65:2: error: #error Oops! Currently hardware SPI is required. Bother Xark if you would like USI or bit-bang SPI supported.

error Oops! Currently hardware SPI is required. Bother Xark if you would like USI or bit-bang SPI supported.

I am not able to implement this but i think there is a way:

PDQ_GFX is mainly focused on AVR parts, so I think this is out of scope for the project. Many of the optimizations aren't as important on faster 32-bit CPUs. That said, if the low-level SPI communication was implemented the library can work on other architectures.
