to get the touchscreen working on a Pi 2 (only one i have tested this project on) i started plugged into an hdmi and did
sudo cp dt-blob.bin /boot/
then in /boot/config.txt
# Disable spi and i2c, we need these pins.
# enable the DPI display
# set up the hsync/vsync/clock polarity and format
# set up the size to 800x480
hdmi_cvt=800 480 60 6
for kali you need to edit config this way as it places the file differently
mount /dev/mmcblk0p1 ~/boot
FInally there is a python configuration tool adafruit has available but it crashes the Kippah!! dont do it from kali!! only from a normal raspian
Add florence virtual keyboard and youre good to go!
