Connect Touchsy HAT to raspberry Pi as shown in pin mapping section
-
Download this github into Raspberry Pi by typing following command into Terminal
git clone https://github.com/sbcshop/3.2_Touchsy_HAT_Resistive_Software/
-
Check if folder downloaded, then just rename folder Touchsy_HAT as shown in below images
-
Open Terminal and run following commands to setup
cd Touchsy_HATsudo chmod 777 *sudo ./Touchsy_HAT 0
Note: We have kept default angle of screen 0 degree, you can change as 90, 180 or 270 as per requirement. E.g.shown below
sudo ./Touchsy_HAT 90Raspberry Pi will restart after this command and screen resolution will be change as per HAT, 240 x 320 pixel, shown below.
-
You will find example python code as Button_Buzzer_demo.py in this repo.
-
Run this code using default python IDE or thonny IDE. This helps to check basic working demo of programmable switches, 5-way switch and Buzzer available on Touchsy HAT. So you can use them to build some automation or add additional functionality to your project.
