difference between counter and digital output

[Emily_aeroeng]

Hello,

What is the difference between a counter and digital output? I may have to write my own I2C driver, and to start with, I know I need to send out the slave address. Would a counter or digital output be better for this?

Thank you!

Emily_aeroeng,

If you're going to be outputting a digital address, you should use digital output.

Counters are versatile devices that can be used to take various measurements on digital signals (frequency, edge count, pulse width, etc.).  They can also be used to output digital pulse trains.
