# 8Bit/16Bit Parallel TFT Library for WiringPi
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.

3.95 inches is almost twice as large as 2.4 inches.
These are OPEN-SMART 16Pin-Parallel Products.

# Software requirement
- 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

# Wirering for 8Bit Parallel

|LCD_RST|--|Pin#7|

|LCD_D7|--|Pin#38|
|5V|--|5V(*)|
|3.3V|--|3.3V(*)|
|GND|--|GND|
\*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".

# How to find the TFT driver name
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](http://domoticx.com/arduino-shield-2-4-tft-lcd-touch/) of the 2.4 inch shield.
You can use [this](https://github.com/prenticedavid/MCUFRIEND_kbv/tree/master/examples/LCD_ID_readreg) 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.__

# Start Auto Demo
./demo
# Start Interpreter mode
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
```
## Take wallpaper from bing and display
To use this, you need python3 and imagemagick.
```
$ sudo apt install imagemagick
$ bash ./bing_wallpaper.sh
```

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

```
cc -o xpt xpt.c xpt2046.c -lwiringPi -lm -lpthread
sudo ./xpt
```
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
```

# 4-wire resistive touch screen
OPEN SMART products have 4-wire resistive touch screen, but Pi cannot use this because Pi cannot input analog.

# JPEG Decoder
This project uses [this](http://elm-chan.org/fsw/tjpgd/00index.html) JPEG library.
This can reduce the image to 1/2 1/4 1/8.
---
# PNG Decoder
I ported the pngle library from [here](https://github.com/kikuchan/pngle).
This can reduce the image to any size.
