Set up PiTFT Screen

Installing Pip

Like many programming ecosystems Python has a sophisticated package management system - [Pip] is the Python package installer.

We will be using Pip extensively in this course.

Let's make sure we have Pip installed for Python3:

sudo apt install python3-pip

Install the PiTFT

We are using Adafruit's 2.8" PiTFT display with capacitive touchscreen. Here is a link to the particular part we are using, the Adafruit PiTFT Plus 320x240 2.8" TFT + Capacitive Touchscreen.

cd ~
sudo pip3 install --upgrade adafruit-python-shell click==7.0
sudo apt-get install -y git
git clone https://github.com/adafruit/Raspberry-Pi-Installer-Scripts.git
cd Raspberry-Pi-Installer-Scripts

We can run the following command to configure the kernel and system for our needs. This will install the 2.8" Capacitive Display, rotated 180 degree (portrait) and configure FrameBuffer Copy (FBCP)

sudo python3 adafruit-pitft.py --display=28c --rotation=180 --install-type=fbcp

NOTE: this will take several minutes to complete.

Select Y when prompted to reboot.

Once the system reboots we'll chose a console font that reads better on the tiny screen. Run:

sudo dpkg-reconfigure console-setup

Select:

  • UTF-8
  • Guess optimal character set
  • Terminus
  • 6x12 (framebuffer only).

Save and quit. Run sudo reboot.
