Then, install teh package for the touch function as well as copy a file:

 

sudo apt

-

get install xserver

-

xorg

-

input

-

evdev

 

sudo  cp 

-

rf  /usr/share/X11/xorg.conf.d/10

-

evdev.conf  /

usr/share/X11/xorg.conf.d/45

-

evdev.conf

 

Restart the Raspberry Pi:

 

sudo reboot

 

5. USAGE OF THE BUTTONS AT THE 3.2"

 

At the side of 3.2" display ais mounted three buttons.

 

 

These can be controlled and used via the GPIO.

 

If the button is pressed, the signal is pulled to ground (Active_LOW).

 

 

The buttons are connected like that:

 

TFT

 

Raspberry Pi

 

Key 1

 

GPIO 12

 

Key 2

 

GPIO 16

 

Key 3

 

GPIO 18

 

6. CALIBRATION OF THE TOUCHSCREEN

 

Calibration of the 3.2" displays:

 

If a calibration of the touchscreen should be necessary, it can be performed 

like  in  the  following  steps.  First  of  all,  you  must  download  the  calibration 

tool. Open the terminal and enter the following command:

 

sudo apt

-

get install 

-

y xinput

-

calibrator

 

 

Restart the Raspberry Pi, so that the display is  identified correctly:

 

sudo reboot

 

Now you can start the calibration with the following command:

 

DISPLAY=:0.0 xinput_calibrator

 

Four points will be light up after another which must be pressed to calibrate 

the display. Afterwards, the terminal issues four calibration values. To save 

the calibration, the adjustment must be saved in a file.

 

 

For that create a new folder:

 

sudo mkdir /etc/X11/xorg.conf.d
