PAKAI SD CARD
1) Pin header solder untuk kartu SD. Ada empat pin yang berlawanan dengan pin tampilan, seperti yang ditunjukkan pada gambar di bawah.
2) Layar dapat memuat gambar lebih besar atau lebih kecil dari ukuran tampilan (160 x 128 px), namun untuk hasil yang lebih baik, edit ukuran gambar Anda menjadi 160 x 128 px.
3) Gambar harus dalam format .bmp . Untuk melakukan itu, Anda dapat menggunakan perangkat lunak pengedit foto dan menyimpan gambar dalam format .bmp .
4) Salin gambar ke kartu SD dan masukkan ke slot kartu SD di bagian belakang layar.
5) HUBUNGKAN PIN DENGAN WIRING BERIKUT:
| Kartu SD pada layar TFT | Pengkabelan ke Arduino Uno |
| CS | 4 |
| MOSI | 11 |
| SUP KEDELAI JEPANG | 12 |
| SCK | 13 |
Layar dan kartu SD berfungsi dengan komunikasi SPI, jadi Anda akan memiliki pin di Arduino dengan dua koneksi.
6) Di Arduino IDE, buka File > Contoh > TFT > Arduino > TFTBitmaLogo .
7) Edit kodenya, sehingga mencari gambar Anda. Ganti “ arduino.bmp ” dengan nama gambar Anda:
// sekarang kartu SD dapat diakses, coba muat file gambar logo = TFTscreen.loadImage(" arduino.bmp ");
8) Upload kode
Dengan Library adafruit ST3375
1) INSTALL LIBRARY ADAFRUIT st3375
2) Klik file>>Example>>st7735>>graphictest
3) atau bisa pakai kode ini

Check out the links above for our tutorials and wiring diagrams.
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional).
