Hi all,
I am aware that USART is commonly used with RS485 and RS232 as USART only implements the link layer and does not specify anything about the electrical wave form.
I would like to ask whether it is suitable to use I2C then a level shifter to RS485 or RS232? If no then why not?
I believe that I2C implements both link layer and physical layer? Please correct me if I am wrong.
Thanks heaps
