Firmata Unit?

[seaton]

Before I reinvent the wheel...

Does anyone know of a unit for the Firmata protocol that I can use in conjunction with an Arduino?

Many Thanks,

Stephen...

For future reference I've written a unit that uses the 5pdo serial component to talk to an Arduino using FirmataLite library and is available here.

Thanks for sharing. It would be nice if you make it public on Firmata official wiki so more people can find it.

I couldn't find any Firmata OPC server and for now I don't have time and motivation to write it on my own, so I will stick to MODBUS/OPC combination to bring AVRs/Arduinos to industrial PLC/SCADA world of control automation. PascalSCADA also has a lot of potential, but it talks MODBUS/S7 and not Firmata or OPC. Hopefully it will be expanded in the near future...

Btw, are you aware of Pascal compilers for AVR/Arduino? I use extensively E-Lab AvrCo Multitasking Pascal with HW debugger/programmer/simulator, but Mikroelektronika Pascal is good too. GCC and Processing are nice and I have used them, but you can guess where my hearth is...

Good idea, will do!

I had a play around with Pascal Scada and the Arduino Modbus library and got things working well when I was investigating protocols and GUI for this project, I do have it Pascal Scada in mind for another project in the near future.

No but am now   I'll have a look thanks
