This is library for RaspberryPi.
You can use a TFT Shield for UNO R3.
This library can show a chart to TFT Shield.
Primarily, these TFT Shiled is the one for Arduino.
This may works with other boards like OrangePi/NanoPi.

These are all 2.4 inch, 320x240 TFTs.
3.95 inches is almost twice as large as 2.4 inches.
These are OPEN-SMART 16Pin-Parallel Products.
- WiringPi Library
This project uses the wiringPiSetup() function to initialize GPIOs.
If you use it on a board other than the RPI board, you may need to change the GPIO number.
As far as I know, there are these libraries.- WiringPi for OrangePi
- WiringPi for OrangePi Zero
- WiringPi for OrangePi3
- WiringPi for BananaPi
- WiringPi for NanoPi
- WiringPi for Pine-64

*When a regulator(It's often AMS1117) is mounted on the back, it's operated 5V.
*When a regulator is NOT mounted on the back, it's operated 3.3V.
NOTE
My R61509V has a regulator on the back.
Normally, a TFT with a regulator works at 5V, but my R61509V doesn't work unless I supply both 5V and 3.3V.
NOTE
You can change any pin.
Pin define is "pin.conf".
If you use a 26-pin header, you can use "pin.conf.26pin" instead of "pin.conf".

The information provided by sellers on Ebay or AliExpress is largely incorrect.
You waste time if you don't choose the right driver.
There are many variations of the 2.4 inch shield.
You can use this to find out your driver.
This is for Arduino UNO.
Do not use this on the RPI as the GPIO on the RPI is not 5V tolerant.
Never believe the seller's information.

You can change draw1.txt & draw2.txt & me.sh
./draw draw1.txt
./draw draw2.txt
bash ./me.sh
Take animal picture from www.365calendar.net and display.
To use this, you need python3 and Pillow.
And reduce the security level of OpenSSL encryption.
$ sudo apt install libtiff5 libopenjp2-7
$ python -m pip install -U Pillow
$ sudo cp /usr/lib/ssl/openssl.cnf /usr/lib/ssl/openssl.cnf.old
$ sudo vi /usr/lib/ssl/openssl.cnf
#CipherString = DEFAULT@SECLEVEL=2
CipherString = DEFAULT@SECLEVEL=1
$ bash ./365calendar.sh
To use this, you need python3 and imagemagick.
$ sudo apt install imagemagick
$ bash ./bing_wallpaper.sh

This module has SPI Touch Sensor.
So you can read touch position.
Use raspi-config to enable SPI.

And you can operate Pi using touch sensor.
cc -o touch touch.c fontx.c tft_lib.c driver/ili9341.c xpt2046.c -lwiringPi -lm -lpthread -DILI9341 -DP16BIT
sudo ./touch
OPEN SMART products have 4-wire resistive touch screen, but Pi cannot use this because Pi cannot input analog.
This project uses this JPEG library.
This can reduce the image to 1/2 1/4 1/8.
I ported the pngle library from here.
This can reduce the image to any size.
