RS232 from T to N

Post by armagon29 »

Dear All:

Could you be so kindly to explain me how to change the Serial output, flowcode macro RS232 normally has a true output, but I have a LCD color Display, it works using an inverted output

Thanks

Hello,

How about using an inverting buffer chip or a diode to flip the logic?

Other then this you will have to use the bit banged mode and manually edit the C code to produce an inverted output signal.

Seems strange though most UART based devices will work with RS232 signal lines being logic high and the start bits being logic low.
