How do you install the latest version of octoprint with LCD TOUCH?

rass

Hi everyone, I'm a novice and I want to install the latest version of octoprint with 3.5 inch LCD touch
My board is an Opi Pc Plus
So far I have only managed to run Octoprint 0.12 without having to run LCD
Is there anyone who can help me ???
P.Š.
The display on the raspberry works with these drivers https://github.com/Elecrow-keen/Elecrow-LCD35

This is also something i would like to know.
Would love to have some advice in installing Octoprint with a touch display.

The make file below is wrong. I don't know what is wrong with it, thus we manually create it.
=========
obj-m := ads7846.o
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

all(MAKE) -C $(KDIR) M=$(PWD) modules

clean(MAKE) -C $(KDIR) M=$(PWD) clean

install(MAKE) -C $(KDIR) M=$(PWD) modules_install

ads7846_device

do a evtest after that to check if touch works.

I have made a working in progress guide to install OctoPrint+TouchUI to OrangePi plus with 7" waveshare touch screen. It is not 100% noob friendly yet, but should not be that hard with someone with some basic knowledge of Linux command line. It should work for other OrangePi's than plus as long as Armbian works. Find it here.
