Post by thread:[SX] serial data, inverted vs true...

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, FORD wrote:Hi all, When you send inverted data instead of true, are all levels inverted, or just the data bits ? The idle state is high and start bit is low for true data, are these also reversed for inverted data ? (dont have a stamp or tools here to check, but would like to know for some hardware design that i may be able to avoid in software).

I'm embarrassed that I asked, its obvious that if you invert the signal in hardware, everythings inverted.. it was 11 pm, i was tired, we won the footy by a point and i was still excited, ... cant think of any other excuses at the moment, but stay posted... oh, also been the victim of a slow optocoupler on an rx circuit (ok at 1200, not at 4800). Cheers, Chris.
