I have a plan to use a SC18IM700 in my project.
Actually My system was controlled I2C, But now i have to change that to TTL UART signal.
Data sheet for SC18IM700 is show me RS232 transmit & receive input.
My issue is that RS232 UART signals are inverted in polarity with respect TTL UART signal.
My system was controlled TTL level circuit. and, I have a control library already.
So, I don't want to change my library. Then, Do i have to add not-gate for my circuit?
I want to get answer clearly.
