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 and the answer I received on the facebook page to run the display
I have not yet tested it

1) LegacyKERNEL
[Only for LCD Display, no touch]
modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:2,dc:71 txbuflen=32768

modprobe flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3

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
=========

MANUAL CREATION
make -C /lib/modules/4.11.3-sun8i/build M=/root/ds7846 modules
make -C /lib/modules/4.11.3-sun8i/build M=/root/ds7846 modules_install

depmod
cd ..
git clone https://github.com/notro/fbtft_tools/
git clone https://github.com/.../fbtft.../tree/master/ads7846_device

cd fbtft_tools/ads7846_device
make
make install
depmod

nano /etc/modprobe.d/ads7846_device.conf

nano /etc/modules-load.d/ads7846.conf
ads7846
ads7846_device

do a evtest after that to check if touch works.
---------- END OF TOUCH-------------

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.
