There are two peice of code that must be present:
- The driver, is the code that runs on Android and tells BRLTTY how to
communicate with the device.
- The firmware, is the "sketch" code that goes into your arduino and tells
the device how to behave.
If you use the arduino, you will have to compile BRLTTY with a driver that
is capable of serial USB interface with the arduino. You can use my driver
if you like.

The driver will be on the arduino itself?
The brltty code is ready and stored in the Android and i should design the
arduino to understand as a device from the devices mentioned , is that
right?

Hello,
I was recently sent this email about using brltty on android. I have no
experience with using brltty on android, so I'm sending it on.
Khaled, as to using an arduino. Yes, you can use an arduino, however you
will have to write your own driver for it, or modify my driver+firmware. In
any case, you will have to use a modified version of BRLTTY. If you use
another micro-controler and use a programmer, than you would be able to
emulate one of the existing braille displays. I don't know how experienced
you are in C, but in either case, you will need at least passable knowlege
of the language, and a relatively large ammount of patience with compilers.

Thanks for your fast response. I connected metec cells with arduino and
wrote code to control pins in terms of the receiving Charts from PC via
serial ports.
But i wish to make my device be compatible with android system (BackBraille
accessibility) or IOS (VoiceOver accessibility), i preferred android because
i saw BRLTTY in github . but till now i cant know from where should i
start, and how should my device be to work with this kind of code, should i
program it with arduino or i have to use other kind of micro controller. I
wish you accept a call from me.
Regards

Hello,
I do not have any experience with metec cells, but I may be able to put you
in contact with someone who does. What is your question?

wish that you can help me. I saw you in github and i want to ask simple
question to put me on the right track. I will call you if you dont complain.
