Description

FirmataLua is an application program to beable to operate GR-KURUMI by using the Firmata protocol.
The program of GR-KURUMI can be written in the Lua language. Aspecial command of digitalWrite etc. was prepared.
It is the same as Luarida of another application program excludinga special command for GR-KURUMI. Please refer to the explanation ofthe command of Luarida.
Still, please feel free to contact me when you want you to add thecommand for GR-KURUMI though the command for GR-KURUMI isinsufficient.
There is Lua program complete set of FirmataLua about the SDcard/FirmataLua/as follows.
Moreover, there are sketch.cpp file and kurumi_sketch.bin file forGR-KURUMI/FirmataLua/sketch/KURUMI/as follows.
Please forward this sketch.cpp and do the build by the Web compileror forward kurumi_sketch.bin to GR-KURUMI.
If GR-KURUMI that writes kurumi_sketch.bin is connected withAndroid by using the FTDI substrate etc. and FirmataLua is started,the communication is begun.
The Lua program is only executed now. Program (lchika.lua) thatlights LED as a sample for KURUMI is appended.

Firmatalua.lua that exists in the FirmataLua folder of the SDcard is the main menu program. This is a selection menu in thescript.
If the made script file name is added to the Menu table offirmatalua.lua, it is OK to start the script of making byoneself.
Moreover, if the short cut is pasted to the home screen, the Luascript can be started directly because the short cut of the luafile can be made.
The explanation of a command is written on the Web site displayedat the end. Please look at the explanation of Lua because thesyntax is Lua language.
The program can be written only with Android by using the editor.Jota Text Editor is recommended.
