I’m a newbie and have a question about UART libraries.

#1 Post by bataradena » 02 Jul 2008 15:16

I’m wondering what’s the big or small different between “Software UART Library" and "UART Library"? Is the different just
“The Software UART” is hardware independent and can be used with any MCU. Is that about it or is there more I should know about.
Thanks
Byron

Mainly-- the software Uarts run code that cannot be interrupted. The hardware Uarts use the internal chip modules to do the timing and buffering and can be interrupted without loosing sync.

Also,
you can program the SOFT_UART essentially on almost any pins of the MCU while the HARD UART is defined by the type of MCU and their PIN assignment.

You don't need to know the answer, you just need to know where to find it!
