I tried a similar sequence on a 24FJ128GA106 and it worked as expected. The original TX pin is correctly deactivated by writing 0 it's RPORx register.
Either you have a simple case of crosstalk, be ... |

What I see is that, first time I run this loop, the first printf ("\n \r Now I use RB15"); is transmitted ok, in RB15 and RB0 stays mute. Then, I configure the RB0 as output and RB15 as def ... |

According to your observation, the problem is, that both outputs are transmitting the data?
But how do you see it? You're executing th ... |

I'll comment the piece of code so we understand each other ;)
//in the .h:
#use delay(clock=20000000)
#pin_select U1TX =PIN_B15 // I set B15 as first output. Later, I'll need to ... |

Hi!
I guess its a good suggestion...
setup_uart(FALSE); I tried with this... but still the same result :( |

Why don't people bother to read the datasheet?
Good question. Apparently also PCD compiler programmers at CCS don't. I missed your previous post,
because I was double checking the unlock code opera ... |

My answer was not an attack on you, rather that this forum is for real PICs, and NOT a Proteus simulator forum.
Simulator's are NOT reliable and are FULL of 'hidden' problems that cannot easily be di ... |

I will ask in other way so no one get offended...
I guess in this part of code im not doing well..
void lockIO(){
#asm
mov OSCCON,w1 //OSCCON defined in .h

What does your program do in the _real_ world? IE, a real PIC programmed with your code?
Gee...Proteus doesn't seem to work ???
I'm amazed at how many have blind faith in that 'simulator'.
I can ... |

I'm (still) writing code for an 18F46J11 -- they're a blast.
It's so nice to have 2 UART's on a small (<64 pin) package.
The re-mappable pins are fabulous (once they work).
Enjoy your 26J1 ... |

Hello, I'm currently writing a piece of code that should be able to change the output and input pin of the UART using the PPS feature. I need to do this while the program is running. So far I have tri ... |
