Coding Arduino Untuk Dot Matrix P10

Coding arduino untuk dot matrix p 10,untuk mnghasilkan karakter atau tulisan di panel dot matrix atau led matrix kalian harus mempunyai program  file hex yang di program menggunakan arduino jadi kalo kalian asal asalan tentang membuat kode file hex maka akan terjadi eror alias gagal program
oke kali ini saya akan ber bagi coding  kepada kalian semua,tapi ingatya coding ini kusus di program arduino dengan rangkaian led matrik p10 atau bisa di sebut 16x32, ingatya rangkaian arduino dan panel led p10 dan yang paling penting adalah kalian harus benar dalam perangkaian dari panel led dan arduino
silakan kopy code di bawah dan masukkan ke arduino

 dmd_test.cpp
   Demo and example project for the Freetronics DMD, a 512 LED matrix display
   panel arranged in a 32 x 16 layout.

 Copyright (C) 2011 Marc Alexander (info <at> freetronics <dot> com)

 See http://www.freetronics.com/dmd for resources and a getting started guide.

 Note that the DMD library uses the SPI port for the fastest, low overhead writing to the
 display. Keep an eye on conflicts if there are any other devices running from the same
 SPI port, and that the chip select on those devices is correctly set to be inactive
 when the DMD is being written to.

 USAGE NOTES
 -----------

 - Place the DMD library folder into the "arduino/libraries/" folder of your Arduino installation.
 - Get the TimerOne library from here: http://code.google.com/p/arduino-timerone/downloads/list
   or download the local copy from the DMD library page (which may be older but was used for this creation)
   and place the TimerOne library folder into the "arduino/libraries/" folder of your Arduino installation.
 - Restart the IDE.
 - In the Arduino IDE, you can open File > Examples > DMD > dmd_demo, or dmd_clock_readout, and get it
   running straight away!

 * The DMD comes with a pre-made data cable and DMDCON connector board so you can plug-and-play straight
   into any regular size Arduino Board (Uno, Freetronics Eleven, EtherTen, USBDroid, etc)

 * Please note that the Mega boards have SPI on different pins, so this library does not currently support
   the DMDCON connector board for direct connection to Mega's, please jumper the DMDCON pins to the
   matching SPI pins on the other header on the Mega boards.

 This example code is in the public domain.
 The DMD library is open source (GPL), for more see DMD.cpp and DMD.h

Perhatian:

• Teliti dan amati di dalam file hex nya jika ada yang kurang dalam meng copy kode maka saat di kompling tidak akan berjalan
•  jika terjadi eror maka akan ada tulisan berwarna kuning dan kalian harus menganti atau mengeditnya,hehe sambil belajar yA
• ganti tulisan ASSALAMUALAIKUM warna merah dengan selera kalian
