Installing drivers?

[siblues]

I am trying to figure out how to use a cheap chinese 3.5TFT with Octoprint and Touch Ui.The screen has a link to a driver but I am unsure of how to install it.The directions are non existent.The driver is ILI9486 and I have tried dragging the folder into my sd card with no luck and I have tried 4 or 5 different ways of installing a desktop and web browser also with no luck.I may have two seperate problems because even after trying to install the desktop and web browser and setting up the RPi to boot to the desktop it doesn't show up either.How hard is it to get the official 3.5TFT working in comparison to one of the knock offs?I can give yo more detailed information if you need it.

The 'Official' Raspberry Pi Foundation display has a 7 inch monitor.

This might be thought too forthright and unhelpful, but here goes -

If your cheap purchase does not work as advertised and expected, perhaps you should return if for a refund and buy one that comes with support to get it to work?

The ILI9486 is a chipset used in many Chinese small screens, usually they are supported by NotroDriver..

I have tried 4 or 5 different ways of installing a desktop and web browser also with no luck.

The FULL version of Raspbian comes with a desktop and browser ready installed.

I understand that the Chinese bits aren't really liked and I get that but I picked one up to learn before spending hundreds on official parts without knowing if I will even be capable of getting them to work.I want to eventually purchase the 7 inch for a car pc I would love to make.

I am currently using Octoprint and I have a very limited knowledge of how any of this works so please bear with me.I Have the Touch Ui loaded because Octoprint has a very simple way to load plugins onto the RPi.I am trying to figure out how and where to load the driver first that way I can make sure it isn't just a driver problem first before assuming it is anything more involved.

Thanks for that link Fruitoftheloom

Where exactly are the drivers located?I am still getting my feet wet with the RPi so it's going to be a while before I know what I am doing.

May i ask if it was advertised for Raspberry Pi or Arduino ? link to web page ?

Here is a link to the screen and it was advertised as a Pi3 screen
https://www.ebay.com/itm/NEW-3-5-TFT-Ra ... SwcqBZxe1F

This is the link to the driver I am trying to use
https://github.com/palmerr23/STM32F01-I ... RPi-Driver

I took a look at the link you provided but I just don't have a grasp of what needs to be done.I have watched a bunch of videos explaining how to install drivers and I have installed a few different kinds of drivers with no luck.The videos all show that the drivers need to be expanded in the home folder on the Pi using the desktop but the driver the screen is specifically calling for doesn't give the option of expanding it.I tried placing it in the home folder with no luck and I also placed it in the boot partition on the sd card and neither worked.The screen is working because it turns on and just displays an all white screen.I am sorry for being such a lost cause.

The ebay pic states Waveshare Spotpear LCD either:

https://www.waveshare.com/product/3.5inch-rpi-lcd-a.htm

Which uses the XPT2046 Chipset, so am now totally confused.

Yeah that is the one and it says on the included paperwork that the ili9486 driver is to be used.I am downloading a Jessie image that is set up for these screens and I will see if that works.I really wanted to tinker with a few of these RPi's but they are looking to be little too complex for me to figure out.I don't mind doing research but I just can't seem to get the hang of it.

[siblues]

I finally got it working.I used the XPT2046 driver and it just rebooted and worked just as it should.Thanks for pointing me in the right direction.

How do I enter or bypass the log in or is there a way to enter the log in through SSH or VNC.The screen is showing a log in now.I can't type in the login name or password with the screen and even after I enter the name and password through SSH the screen is still asking for it.I have tried bypassing it a few different ways with no luck.I have tried setting up the Pi to boot to Desktop/CLI with and without auto login and that makes no difference.

Any insight on how I can get around the login?
