TinyLCD Setup

Instructions to install the NeoSec 3.5" TinyLCD drivers on a Raspberry PI:

1. Enable SPI – comment out the spi blacklist line

    sudo nano /etc/modprobe.d/raspi-blacklist.conf
   

2. Install FBTFT drivers as loadable modules

     sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update
     sudo reboot
   

3. Register device (the driver will load automatically)

    sudo modprobe fbtft_device name=tinylcd35
   

4. dmesg will show the default pin assignements, and that the driver is loaded.

5. Tell the OS to load the driver on boot – edit /etc/modules

    fbtft_device name=tinytft35 verbose=0 rotate=90
   

6. Tell the driver to show the console – edit /boot/cmdline.txt

    fbcon=map:10
   

Is this still necessary to get a TFT running, particularly the TinyLCD 3.5"? Or is this outdated?

I rebooted on step two and now it wont boot back on. what should i do?
