Hi, All

 

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.

 

Thanks,

Dongsoo
