Deskripsi layar sentuh LCD TFT ILI9341.
Modul LCD TFT adalah salah satu perangkat yang paling populer
di sejumlah proyek mikrokontroler terutama modul port serial, karena
membutuhkan sedikit pin I/O dan penggunaannya umumnya sederhana. Dalam pembahasan
kali ini mencoba menghubungkan layar sentuh LCD 2.4″ TFT dengan driver ILI9341
dengan Arduino. Modul LCD ini bukan hanya layar saja, tetapi juga tersedia slot
untuk kartu SD. Lcd ini memiliki resolusi 240 x 320 piksel untuk layar LCD TFT
2,4 inci dan menggunakan driver ILI9341. Layar menggunakan antarmuka serial dan
dikendalikan oleh 5 kabel (CS, RS, SCL, SDA, RST). Kartu SD juga menggunakan
antarmuka SPI perangkat keras (CS/MOSI/MISO/SCK).
Berikut adalah bagian-bagian dari LCD 2.4″ TFT SPI

T_IRQ :Touch screen interrupt signal,
low level when touch is detected
Menghubungkan layar TFT 2,4 ”dengan Arduino
LCD ini bisa digunakan menggunakan layer sentuh dan tidak menggunakan layer sentuh. Mari kita gunakan layar sebagai layar TFT biasa tanpa fungsi sentuh. Untuk ini kami hanya menghubungkan sembilan pin pertama dari layar.
Catatan
:
Pin
modul SPI LCD hanya dapat memasukkan level tinggi 3.3V, sedangkan output
Arduino memiliki level tinggi 5V. Dan masalah utamanya modul tampilan LCD ini
tidak toleran dengan tegangan 5V.
Masalah ini dapat diatasi dengan menghubungkan Arduino dan modul tampilan melalui modul konversi level eksternal, sehingga output Arduino level tinggi 5V diubah menjadi 3.3V oleh modul konversi level dan kemudian dimasukkan ke modul tampilan. Jika Anda tidak memiliki modul konversi seperti itu, Anda dapat menggunakan beberapa resistor 10K seperti yang ditunjukkan pada skema di bawah ini.

Sejumlah library telah
dikembangkan untuk memudahkan penggunaan tampilan layar sentuh LCD 2.4″ TFT ini
dengan Arduino. Namun dapat ditemukan sejumlah library menarik dengan contoh
yang dapat membantu pemula memahami cara kerja tampilan ini di www.lcdwiki.com.

hasilnya kira-kira seperti dibawah iniMenggunakan fungsionalitas sentuh layar TFT ILI9341 2,4″.
Untuk dapat menggunakan fungsionalitas sentuh pada layar, kami menghubungkan lima pin yang tersisa sesuai dengan diagram skema di bawah ini.

Kita dapat menggunakan kode di bawah ini untuk menguji fungsionalitas sentuh. Ketika kode ini diunggah ke Arduino, kita dapat menggunakan pena sentuh untuk menulis di layar menggunakan teks dengan warna dan ketebalan yang berbeda.
