# ST7735 library for Raspberry PI
 [](LICENSE.md)
A port of [ST7735 Arduino library](https://github.com/adafruit/Adafruit-ST7735-Library) and [ST7735 GFX Arduino library](https://github.com/adafruit/Adafruit-GFX-Library) to Raspberry PI using [wiringPi](https://github.com/WiringPi). The idea was to be able to control ST7735 TFT LCD on Raspberry PI using C++ instead of the regular Python libraries.
Supported screens are :
* [Adafruit ST7735 1.44'](https://www.adafruit.com/product/2088)
* [Adafruit ST7735 1.8'](https://www.adafruit.com/product/358)
Features implemented :
- [x] fill screen
- [x] draw rectangle
- [x] draw text
- [x] draw bitmap
- [ ] read bitmap from SD card
- [ ] draw vertical line
- [ ] rotate screen
- [ ] custom fonts
- [ ] all other features of Adafruit-ST7735-Library
## Prerequesites
* wiringPi
* cmake
## Install library
On your Raspberry PI :
```bash
git clone git://github.com/bertrandmartel/st7735-raspberry
cd st7735-raspberry
cmake .
make
sudo make install
```
* Check the testing example (you may need to edit RST and DC pin inside `examples/main.cpp` :
```bash
./out/examples/main
```
## Wiring
| description | WiringPi | Physical pin|
|---------------|----------------|------------|
| VCC | - | 2 |
| GND | - | 14 |
| DC | 5 | 18 |
| MOSI | 12 | 19 |
| RST | 6 | 22 |
| CS | 10 | 24 |
| SCK | 14 | 23 |
In the library only RST and DC can be configured :
Check the pin diagram with `gpio readall`
1.44' | 1.8'
:-------------------------:|:-------------------------:
 | 
## Using the library
```cpp
#include "st7735.h"
#include "wiringPi.h"
#define TFT_RST 6
#define TFT_DC 5
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_DC, TFT_RST);
void setup() {
wiringPiSetup();
//tft.initR(INITR_144GREENTAB); //for 1,44'
tft.initR(INITR_BLACKTAB); //for 1.8'
}
int main() {
setup();
//fill screen with color
tft.fillScreen(ST7735_BLACK);
//draw a rectangle
//tft.fillRect(10, 10, ST7735_TFTWIDTH_128 - 20, ST7735_TFTHEIGHT_128-20, ST7735_WHITE); //for 1.44'
tft.fillRect(10, 10, ST7735_TFTWIDTH_128 - 20, ST7735_TFTHEIGHT_160-20, ST7735_WHITE); //for 1.8'
delay(750);
tft.fillScreen(ST7735_BLACK);
//draw text
tft.setTextBackground(ST7735_BLACK);
char hello[] = "Hello world !\nHello world !\n";
tft.drawString(hello, ST7735_WHITE, 1);
delay(1000);
tft.drawString(hello, ST7735_GREEN, 1);
delay(1000);
tft.drawString("H", ST7735_BLUE, 1);
tft.drawString("E", ST7735_BLUE, 1);
tft.drawString("L", ST7735_WHITE, 1);
tft.drawString("L", ST7735_WHITE, 1);
tft.drawString("O", ST7735_RED, 1);
tft.drawString("!", ST7735_RED, 1);
//draw bitmap
//tft.draw_bitmap_st7735(0, ST7735_TFTHEIGHT_128, imageLogo, ST7735_TFTWIDTH_128, ST7735_TFTHEIGHT_128); //for 1.44'
//tft.draw_bitmap_st7735(0, ST7735_TFTHEIGHT_160, imageLogo, ST7735_TFTWIDTH_128, ST7735_TFTHEIGHT_160); //for 1.8'
return 0;
}
```
## Compile code linking to library
```bash
g++ main.cpp -lwiringPi -lst7735 -o main
```
## Cross compilation
Get the [raspberry-dev](https://github.com/bertrandmartel/raspberry-dev) submodule by issuing :
```bash
git submodule update --init --recursive
```
Use the `build.sh` script to cross compile the library :
```bash
./build.sh
```
This will invoke `cmake . -DCMAKE_TOOLCHAIN_FILE=./raspberry-dev/toolchain.cmake` which will automatically download the toolchain and wiringPI library
