[Arduino Project] Interface Joystick PlayStation dengan Arduino

Dapat project dari temen disuruh buat robosoccer. Dia punya ide memakai stick PlayStation yang wireless. Lumayanlah stick wireless sekarang sudah semakin murah dipasaran.

Browsing di internet ternyata stick PS menggunakan komunikasi SPI sebagai interfacenya. Bill porter ternyata sudah meriset ini dengan sangat baik dan membuatkan librarinya. Bill menggunakan SPI dengan software, artinya bukan pada pin MOSI MISO SCK pada arduino melainkan menggunakan pin bebas sesuai selera kita. Website Bill Porter dapat di buka disini. Librarinya bisa di didownload disitu juga. Apabila menginginkan program saya sekaligus library yang sudah saya edit bisa didownload disini

Saya menggunakan kabel untuk menjumper arduino ke connector PS tersebut. Konektornya wiringnya sebagai berikut:

Sedangkan pada arduino wiringnya sebagai berikut:

Saya mengedit software examplenya dengan mendeteksi tombol ditekan dan tombol dilepaskan sebagai berikut:

Program diatas hanya men-scan tombol dan mendeteksi perubahan tombolnya termasuk perubahan analog joysticknya. Saya juga mematikan beberapa fitur seperti getar dan analog pada tombol PAD(tombol arah). Akan tetapi program diatas agak sering beberapa kali tidak mendeteksi stick PSnya, wahhhh. Akhirnya saya browsing lagi menemukan beberapa stick PS menggunakan SPI clock yang lambat. Saya mengambil kesimpulan kalau library Bill Porter ini terlalu cepat buat stick PS punya saya (buatan china). Akhirnya saya terpaksa mengedit Librarinya akhirnya menemukan cara memperlambat SCKnya. Saya mengedit PS2X_lib.h sebagai berikut :

92 93 94 95 96 97

#ifdef __AVR__ // AVR #include <avr/io.h> #define CTRL_CLK 4 #define CTRL_BYTE_DELAY 3 #else

saya edit menjadi:

92 93 94 95 96 97

#ifdef __AVR__ // AVR #include <avr/io.h> #define CTRL_CLK 10 #define CTRL_BYTE_DELAY 10 #else

Akhirnya stick PS langsung terdeteksi setiap kali di reset Arduinonya. Tombolnya juga responsif, joystick analognya akan di print apabila ketika ada perubahan saja, jadi data tidak mengirim terus-terusan.

Selamat Mencoba.
