hey all
i need some help please
i know that UART is a h.w device represents a communication protocol
but
1 - what is RS-232 ? is it protocol ? or just interface ? what is meant by interface ?
2 - if Rs-232 is interface for serial communication why we can't use it with SPI , I2C ?
3 - if it is an interface to map MC voltage Level to communicate with other devices such as PC's
so why we still use MAX-232 ?
thanks
