About this app

FirmataMruby is an application program to be able to operate GR-KURUMI by using the Firmata protocol.
The program of GR-KURUMI can be written in the ruby language. A special command of digitalWrite etc. was prepared.
It is the same as Yamruby of another application program excluding a special command for GR-KURUMI.
In addition, the heading character of the class name becomes a capital letter as for the command of Yamruby though it is almost the same as Luarida of another application program.
Yamruby has opened the source to the public to github, and refer to fvmExec.c for details, please.
Still, please feel free to contact me when you want you to add the command for GR-KURUMI though the command for GR-KURUMI is insufficient.
There is ruby program complete set of FirmataMruby about the SD card/FirmataMruby/as follows.
Moreover, there are sketch.cpp file and kurumi_sketch.bin file for GR-KURUMI/FirmataMruby/sketch/KURUMI/as follows.
Please forward this sketch.cpp and do the build by the Web compiler or forward kurumi_sketch.bin to GR-KURUMI.
If GR-KURUMI that writes kurumi_sketch.bin is connected with Android by using the FTDI substrate etc. and FirmataMruby is started, the communication is begun.
The ruby program is only executed now. Program (lchika.rb) that lights LED as a sample for KURUMI is appended.

Firmatamruby.rb that exists in the FirmataMruby folder of the SD card is the main menu program. This is a selection menu in the script.
If the made script file name is added to the Menu table of firmatamruby.rb, it is OK to start the script of making by oneself.
Moreover, if the short cut is pasted to the home screen, the ruby script can be started directly because the short cut of the rb file can be made.
The explanation of a command is written on the Web site displayed at the end. Please look at the explanation of ruby because the syntax is ruby language.
The program can be written only with Android by using the editor. Jota Text Editor is recommended.
