Raspberry Pi with stroke and Gesture Recognition

If you are using a touchscreen with your Raspberry Pi, then this guide is for you.

Xstroke (Gesture recognition) is the perfect tool to help you get more out of your touhscreen. I am using a PiScreen

Gesture recognition allows you to draw “strokes” on your touchscreen, which get interpreted as commands or text. Xstroke allows these to be entered anywhere on the screen. In some cases, Xstroke can be used instead of a keyboard.

PiScreen – 3.5″ TFT(480×320) with touch control for the Raspberry Pi – Kickstarter launched

We have launched a Kickstarter campaign for a 3.5″ TFT (480×320) with touch control, we have given it the name of PiScreen.

PiScreen includes a 3.5″ TFT with touchscreen control, PCB and components needed to add this display to a Raspberry Pi.

PiScreen connects right on top of the Raspberry Pi GPIO pins


The TFT used is the best quality we have seen so far.

How to Control the GPIO on a Raspberry Pi with an IR Remote

In this post I demonstrate how to use an infrared remote to control the GPIO on a Raspberry Pi.

Normally a remote would be used to control a TV card or XMBC, however they also provide a good interface to control the GPIO on a Raspberry Pi.
Adafruit has a Mini Remote and IR sensor which are perfect for this.

In this example we will use the remote to control a number of LEDs connected to some GPIOs on a Raspberry Pi.

Connect the IR Sensor to the Raspberry Pi

Connecting the IR sensor to a Raspberry Pi is very easy as there are only 3 pins on the sensor, GND, 3v and Output. We will connect the output to GPIO 18. You can choose another pin, just take note of it as you will need to specify this pin when installing LIRC.
We will also connected up three LEDs to GPIOs 23, 24 & 25, and a 270Ω on the GND sound of each LED.


Here is my setup;
