I try to implement
Firmata protocol (plain java implementation to use in JavaFX apps and Android apps) and use Processing source code as an example.
I found that some "must-have" methods are not implemented: f.e. missing "report digital port" message:
private final int REPORT_DIGITAL = 0xD0; // enable digital input by port
In source code file (Arduino.java) the constant is introduced but is not used anywhere.
I have few more questionы and will be
grateful for the help.
