Hi,

Does GTT480272A support I2C now?

Hi,

Does GTT480272A support I2C now? I got this question because in one of the thread "232TTL or I2C ?" dated Nov 01, 2010, it was replied saying it does not support I2C yet.

I am planning to use I2C communication with GTT480272A. Is it possible now?

Thanks in advance...
