Software

Build and transfer

Clone the source code and open the project file "ArduinoX2PAV.ino" with Arduino IDE.

You can build the source code with following configuration.

• Board: "Arduino Nano"
• Processor: "ATmega328P (Old Bootloader)"

Then, you can transfer binary data to Arduino Nano by usual way.

Append new scenario

You can design new scenario using Arduino X2PAV Scenario Editor.

This tool outputs a header file as scenario data.

To append the scenario you designed, edit "ArduinoX2PAV.ino".

• Include the header file.
• Add SEQUENCE_DATA macro to the sequences[] array.

 #include "data/sample1.h"
 #include "data/sample2.h"
 #include "data/sample3.h"
+#include "data/foo.h"

     (ellipsis)

 PROGMEM static const SEQUENCE_T sequences[] = {
     SEQUENCE_DATA(sample1),
     SEQUENCE_DATA(sample2),
     SEQUENCE_DATA(sample3),
+    SEQUENCE_DATA(foo),
     NULL
 };
