“The hardware itself is working fine, though it seems currently the drivers still are not fully fleshed out. I had to manually modify /etc/modules to get the console driver to work (seems like spi-bcm2835 needs to be on top, since the display driver depends on it). I was unable to get the HDMI mirroring functionality to work with the drivers supplied from Adafruit. Instead, I used fbcp-ili9341 (Luckily, the Adafruit documentation includes all information needed for figuring out the build parameters: -DST7789=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_BACKLIGHT=22, and I also needed -DUSE_DMA_TRANSFERS=OFF, otherwise the display would stay black). On a different note, I find the hat rather pricey considering how cheap these displays are if bought from China.”
