Simple question; what is a UART? Now for you Google happy people, that is getting old. I ask because i want a response here. I should not have to explain that anymore...
Anyways, i know that UART stands for Universal Asynchronous Receiver Transmitter, but what exactly does a UART do? And how much does it do? Since it is used in RS232 communications, how much of that does it do? For example, could i just send an 8bit number to it, and have it do all the work of sending it for me? Or would the sender (microcontroller) have to do more work than just send the number to it? Also, on the other hand, with a MAX232, could i just send data to it from my RS232 port (com) on my computer, and have it decode the number sent to it and put it into 8bit parallel?
