Hi,
I need two chips within the same device to communicate via UART. The device needs to survive wild temperature variations. It is my understanding that temperature affects clocks, even crystals, and affect them differently. What will that do to my UART?
This may be a total noob question, but is there any way to synchronize two chip's clocks?
Also, I've heard that UART is decades old and not a great protocol. Is it true? And what are the alternatives?
