'DMX Sender (Serial port behavior)'

Hello all,

   my DMX Sender is almost ready, Just one more question:

   When I set TXEN (Transmit Enable bit) and SPEN (Serial Port Enable bit),
and do not set CREN (Continuous Receive Enable bit), I loose PORTC.7 (RX)?

   I'm asking this, because I'm not using the PORTC.7 for the USART (I'm
only sending DMX, not receiving anything) and wants to use it for the 7LED
display, but seens to be always in high impedance state.

   As we're talking a lot about pins in high impedance, I think I'll have
to pull this pin high (serial break) with a resistor.

   Best regards and thanks,

   Brusque

Yes, as soon as the SPEN bit is set, both pins (RX & TX) are reserved for
the UART.

I had this same problem with one of my projects.
