supported? 7 pins -> without CS pin? #178

hi, i trying to get fbcp-ili9341 running. but no success. instead this python code runs on the same wiring perfectly: https://github.com/solinnovay/Python_ST7789 seems to be a 7789 driver with the CS-Pin missin on my display. this python-lib works.

i tried all this without any reaction on the display. maybe there is a foolproof way to get an image on the display while this fbcp-ili9341 is running?

this is my wiring. works with the python-example. but with same wiring not with the fbcp-ili9341. i am on an old rasperry 

cat /proc/device-tree/model
Raspberry Pi Model B Rev 2

appreciate any hint/help. thanks
