-- Detected this Pi to be one of: Pi 2B rev. 1.2, 3B, 3B+, CM3 or CM3 lite, with 4 hardware cores and ARMv8-A instruction set CPU.
-- Enabling optimization flags that target ARMv8-A instruction set (Pi 2B >= rev. 1.2, 3B, 3B+, CM3 or CM3 lite)
-- Scaling source image to view. If the HDMI resolution does not match the SPI display resolution, this will produce blurriness. Match the HDMI display resolution with the SPI resolution in /boot/config.txt to get crisp pixel perfect rendering, or alternatively pass -DDISPLAY_CROPPED_INSTEAD_OF_SCALING=ON to crop instead of scale if you want to view the center of the screen pixel perfect when HDMI and SPI resolutions do not match.
-- Preserving aspect ratio when scaling source image to the SPI display, introducing letterboxing/pillarboxing if HDMI and SPI aspect ratios are different (Pass -DDISPLAY_BREAK_ASPECT_RATIO_WHEN_SCALING=ON to stretch HDMI to cover full screen if you do not care about aspect ratio)
-- SPI_BUS_CLOCK_DIVISOR set to 16. Try setting this to a higher value (must be an even number) if this causes problems. Display update speed = core_freq/divisor. (on Pi3B, by default core_freq=400). A safe starting default value may be -DSPI_BUS_CLOCK_DIVISOR=40
-- USE_DMA_TRANSFERS enabled, this improves performance. Try running CMake with -DUSE_DMA_TRANSFERS=OFF it this causes problems, or try adjusting the DMA channels to use with -DDMA_TX_CHANNEL= -DDMA_RX_CHANNEL=.
