[[File:Config-difference.jpg|config.txt difference | 800px ]]

[Update]:You can use this script tool to use this LCD now: https://github.com/geekworm-com/22LCD-script

or download this [[File:Config.zip |config.txt on on 2019-06-20 raspbian-buster]], then unzip it, and move it to /boot/

== How to use this screen for PI 3B+/3B/2B ==
We update the user method for the old raspberry pi board such as 3B+/3B/2B etc. Only append the following comment to the end of '''config.txt''' file;

We test it on the official Rasdpbian 2018-11-13-raspbian-stretch verson.

=== How to change the backlight, push the button ===
[[File:35inch-HD-TFT1.png]]

=== How to use 2 keys,like gpio ===
[[File:35inch-HD-TFT2.png]]

=== How to use the I2C master(I2C_3) ===
you can use this module by the following step

step 1.
Download the official firmware, then upgrade to the latest kernel
sudo rpi-update

step 2.
Config file to enable i2c_3
sudo nano /boot/config.txt

Add the following line:
dtoverlay=i2c-gpio,i2c_gpio_scl=24,i2c_gpio_sda=23framebuffer_height=480

step 3.
Make and install the pigpio
sudo git clone git://github.com/joan2937/pigpio
cd pigpio
sudo python setup.py install
sudo make
sudo make install

step 4.
install the I2C tools
sudo apt-get install i2c-tools python-smbus

step 5.
Config file to /etc/modules
sudo nano /etc/modules

Add the following line:
i2c-bcm2708
i2c-dev

step 6.
Config file to /etc/ rc.loacl
sudo nano /etc/ rc.loacl

Add the following line:
raspi-gpio set 23 pu
raspi-gpio set 24 pu

step 7.
Save then restart;

=== How to use the IR function ===
Description:
'''IR receiver function:'''
* Operating frequency: 38K HZ
* Receiving distance: 18-20m
* Reception angle: +/- 45 degrees
'''The infrared transmitter function'''
* Wavelength: 940nm
* Transmitting distance: 7-8m

Preparation: Burn into raspbian system;

1. Start the Raspberry Pi, login Raspberry Pi through SSH, the user name: pi, default password: raspberry

2. Update and install lirc software, run the following command:
sudo apt-get update
sudo apt-get install lirc
[[File:35inch-hd-tft3.jpg|600px]]

[[File:35inch-hd-tft4.jpg|600px]]

3. Edit the config.txt, and add configuration. use GPIO PIN 26;
sudo nano /boot/config.txt

Add the following line into the config.txt file:
dtoverlay=lirc-rpi, gpio_in_pin=26
[[File:35inch-hd-tft5.png|600px]]

4. Edit LRIC config file to enable infrared function;
sudo nano /etc/lirc/hardware.conf

Modify the following lines:
LIRCD_ARGS=”--uinput”
DRIVER=”default”
DEVICE=”/dev/lirc0″
MODULES=”lirc_rpi”

5. Run "sudo reboot" to restart the Raspberry Pi, then run "ls / dev / l *" to view the infrared device is enabled

[[File:35inch-hd-tft7.jpg|600px]]

It's enabled if you can view the above red mark;

6. Record Button
sudo /etc/init.d/lirc stop
sudo irrecord -n -d /dev/lirc0 ~/lircd.conf
Record your IR remote control Follow the prompts, such as “pause”，“nextsong”，“prevsong”，“stop”，“volumeup”，“volumedown” etc.

[[File:35inch-hd-tft8.jpg|600px]]
then you can get a lircd.conf file; override the old lircd.conf file;
sudo cp ~/lircd.conf /etc/lirc/lircd.conf

7. Startup lirc software;
sudo /etc/init.d/lirc start
[[File:35inch-hd-tft9.jpg|600px]]

8. Run the following command to view & check record result
sudo irw
Then press those record button;

9. You can view those button name to run irsend command;
irsend LIST /home/pi/lircd.conf “”
maybe it's following content:
irsend: 000000000000c837 pause
irsend: 00000000000048b7 nextsong

10. Now you can use the infrared transmitter, recorded before launching the remote control key coding, use that will extend the board as a rotary tool.Launch the command reference command:
irsend SEND_ONCE /home/pi/lircd.confpause
irsend SEND_ONCE /home/pi/lircd.confnextsong
irsend SEND_ONCE /home/pi/lircd.conf KEY_VOLUMEDOWN
irsend SEND_ONCE /home/pi/lircd.conf KEY_VOLUMEUP
